Abracon announces ASMPH family of compact multi-layer chip inductors for power applications

AUSTIN, TX. (19 January 2017) Abracon, LLC. (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components announces the ASMPH family of miniature multilayer power inductors for use in small form factor or battery powered solutions. The compact size, high self-resonant frequency (SRF)  and high efficiency, makes these inductors ideal for DC/DC conversion in space limited designs, including IoT and wearables. Standard operating temperature of -40°C to 85°C and robust construction is ideally suited for industrial applications. Constructed using low loss ferrite material, these inductors support high-speed switching frequencies used in power supply controllers in advance-miniaturized applications.

This family of power inductors offers multiple footprints and inductance tradeoffs. The space saving ASMPH-0603 footprint is 1.6×0.8×0.8mm with current ratings from 1250mA to 300mA and inductance values from  0.22µH to 2.2µH. With inductance values up to 4.7µH, the ASMPH-0805, ASMPH-0806 and ASMPH-1008 offer current carrying capabilities up to 1500mA, enabling a wide range of DC/DC power supply applications.

“Small form factor solutions benefit from the use of DC/DC power conversion,” comments Syed Raza, VP of Engineering with Abracon. “Switch mode, unlike linear power supplies, can remain efficient while operating over a wide input-to-output voltage conversion range, extending battery life. This family of miniature inductors from Abracon are instrumental in miniaturizing these designs.”

“These inductors hit the sweet spot of size, inductance, current carrying capability and maximum DC resistance enabling miniaturization.” states Juan Conchas, Director of Marketing for Abracon. “In conjunction with Abracon’s other product lines, these inductors address Abracon’s strategy of providing solutions across multiple technologies for growing applications such as IoT and wearables.”

Other applications for this series of product include medical monitoring, portable instrumentation, drones, robotics, battery powered equipment,  asset tracking devices, wireless connectivity modules and power supply modules.

Abracon Pierce Analyzer System (PAS) validates quartz crystals in-circuit

PAS-BC1WK/ PAS-BC2WK/ PAS-BC3WK

(Austin, TX) Abracon, LLC (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components announces the availability of an advanced proprietary Pierce analyzer system that validates quartz crystal performance in-circuit. The ability to sustain oscillation for a given quartz crystal oscillator design depends heavily on crystal’s motional parameters, board parasitics and oscillator circuit characteristics. The oscillator circuit is a closed loop system that sustains oscillation at an operating frequency, depending on the crystal plating capacitance (CL), crystal equivalent series resistance (ESR) and Oscillator Amplifier’s gain & phase response. Lower CL and lower ESR at the crystal level, enables the circuit to operate with adequate gain margin and improves the closed-loop stability; ensuring sustained oscillations across all variables, including variation in bias, loading, temperature and over time. Integrated circuits that use external quartz crystals do not always account for these key limiting factors. For instance, estimating or simulating the effect of board parasitics is not always possible. In-circuit testing of the quartz crystal while connected to the oscillator IC and attached to the board reveals design errors and inaccuracies that may cause over-drive, under-drive or center frequency deviations; or even the ability to sustain oscillations.

“Overdrive on the crystal causes long term reliability concerns due to microfractures within the crystal lattice. Under-drive may lead to complete oscillator loop failure, and center frequency errors as high as +/-500 parts per million may be completely out of range of acceptable frequency drift for a given application,” says Syed Raza, VP of Engineering with Abracon. “To conserve power, next generation IC’s must lower the gain in the oscillator loop requiring quartz crystals with much lower ESR at lower plating load. With next generation ultra-low power circuits used in the Internet of Things (IoT) and wearables, fabricated in <14 nanometer geometry; it’s no longer safe to assume that the oscillator will operate with sufficient gain margin, especially over temperature and time.

“The quartz crystal oscillator,” says Juan Conchas, Director of Marketing with Abracon, “sets the beat of the entire system. As oscillators are starved of power, failure to operate or operation off-center frequency is much more likely and more challenging to correct. For this reason, the ability to verify the performance of the crystal oscillator loop in-circuit, has become a necessary step in validating the overall system design.”

The service provides a comprehensive report outlining the functional parameters of the oscillator circuit and recommends changes when necessary. This service is conducted by Abracon and can be ordered through any franchised distributor, with multiple turn-around times from 2-week to 4-weeks.

Abracon, LLC introduces robust RFID tags designed for metal surfaces

(Austin, TX) Abracon, LLC (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components introduces a broad family of fully integrated passive RFID tags operating in the UHF band optimized for use on metal surfaces. These devices offer FCC compliance over 902MHz to 928MHz with multiple form factors that cover read ranges up to 9 meters. The tags are optimized to be directly attached to metal surfaces without limiting the available read range. Unlike fragile inlay tags used on consumer applications, these devices are robust and durable designed for long term use in harsh demanding environments, and are not de-tuned by the metal surface. This extends asset tracking and asset management capabilities into a new class of applications previously unattainable with lower performing tags.

The devices integrate and Alien H3 IC and high performance antenna that enables support for ISO 18000-6C/EPC Class1 Gen2. The family offers multiple form factors with small space saving 5x5mm footprint up to 9meter long read range 25x25mm footprints. Two operating temperature ranges of -30C to 85C and -40C to 85C are available for wide temperature industrial applications.

“With the ability to significantly improve operational efficiency and curb losses, asset tracking and asset management is now playing a wide role in applications as varied as industrial automation, transportation, cloud computing, agriculture, smart building structures and heavy machinery,” comments Juan Conchas, Director of Marketing for Abracon. “Because RFID is a non-line of sight technology that can achieve a substantial range, passive RFID tags are an important component within asset tracking and asset management solutions.”

“Developing RFID tags that respond well when directly attached to large hunks of metal is necessary given that antenna performance is influenced by the environment in which they are sited.” says Dean Clark, Senior Technical Manager with Abracon. “Thin In-lay RFID tags are affected by the metal areas that de-tune them, these ceramic tags were designed for use directly on metal, large metallic objects like shipping containers, vehicle chassis and heavy machinery can be easily tracked.”

The RFID tags are in stock and available through any of Abracon’s franchised distributors.
