AVX Launches New TCO Series High-Temperature, Automotive-Grade Polymer Chip Capacitors

Rated for operating temperatures up to 150°C at category voltage, the new TCO Series capacitors meet AEC-Q200 requirements, exhibit low DCL and a benign failure mode, and are ideal for use in low- and medium-power automotive, industrial, and telecommunications applications.

FOUNTAIN INN, S.C. (September 16, 2021) – AVX Corporation, a leading manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, released the new TCO Series high-temperature, automotive-grade polymer chip capacitors, which are rated for operating temperatures up to 150°C at category voltage and meet AEC-Q200 Stress Test Qualification for Passive Components requirements, which ensure stable performance at 85°C, 85% relative humidity, and rated voltage for up to 1,000 hours. Based on AVX’s field-proven TCQ Series automotive polymer capacitors, the new TCO Series chip capacitors are manufactured in an IATF-16949-certified facility and feature robust J-lead constructions comprised of tantalum anodes, tantalum pentoxide (Ta2O5) dielectrics, and conductive polymer electrodes that exhibit a benign failure mode under recommended use conditions. The series also exhibits low DCL (0.1CV) and basic reliability of 1% per 1,000 hours at 85°C and rated voltage with 0.1Ω/V series impedance and 60% confidence, and is ideally suited for use in high-temperature, low- and medium-power automotive, industrial, and telecommunications applications.

TCO Series capacitors are currently available as D-case (EIA Metric 7343-31) components rated MSL 3 per J-STD-020 and for 10µF ±20% tolerance, 50VDC at 105°C, a maximum of 50µA DCL, 150mΩ maximum ESR at 100kHz, and operating temperatures extending from -55°C to +150°C, but several other codes are actively in development. They are also RoHS compliant, lead-free compatible, and capable of withstanding three reflow cycles at 260°C. Ideal applications for the series include automotive cabin control, infotainment, and comfort systems; body electronics that manage safety, power management, and diagnostic systems; and aftermarket electronics such as dash cams, radar detectors, navigation systems, subwoofers, amplifiers, and headrest monitors; as well as DC/DC converters and coupling/decoupling circuits in industrial and telecommunications equipment.

“The new TCO Series high-temperature, automotive-grade polymer chip capacitors are based on our TCQ Series automotive polymer capacitors, which now have more than five years of field-proven success,” said Allen Mayar, AVX Electrolytic Capacitors global product manager. “Both polymer capacitor series satisfy the stringent AEC-Q200 requirements for automotive use thanks to superior material selections, design decisions, and manufacturing processes, and the new TCO Series offers the additional benefit of 150°C operation at category voltage.”

TCO Series capacitors are shipped on seven- or 13-inch pure tin reels for automated assembly and lead-time for the series is currently 20 weeks.

Silicon Lifecycle Management Paradigm Shift

Sponsored by Synopsys

An end-to-end platform solution, Silicon Lifecycle Management leverages existing, mature, world-class technologies within Synopsys. This exciting new concept will revolutionize the semiconductor industry and how we manage silicon design. For the first time, designers can look inside silicon chip devices from the moment the design is created to the point at which they end their life.

How to Design with Maxim’s Latest Supervisors

Sponsored by Maxim Integrated (now part of Analog Devices)

As the technologies in MCUs, µPs, DSPs, and FPGAs move toward lower geometries and power, operational voltages become significantly low for these devices. Reducing the core voltage poses challenges in the use of high-accuracy power supply and voltage supervisors to avoid system failure. This application note discusses the critical parameters Maxim’s MAX16132–MAX16135 supervisor family and presents a reasonable approach in choosing the right reset threshold and hysteresis for voltage supervisor ICs.

Flexible Power for a Smart World

Sponsored by Mouser Electronics and CUI Inc.

Safety, EMC compliance, your project schedule, and your BOM cost are all important factors when you are considering what power supply you will need for your next design. You also need to think about form factor, which capacitor will work best, and more. But if you’re not a power supply expert, this can get overwhelming in a hurry. In this episode of Chalk Talk, Amelia Dalton chats with Ron Stull from CUI Inc. about CUI PBO Single Output Board Mount AC-DC Power Supplies, what this ??ac/dc core brings to the table in terms of form factor, reliability and performance, and why this kind of solution may give you the flexibility you need to optimize your next design.
