Vishay Introduces AEC-Q200 Qualified Extremely High Reliability Thin Film Chip Resistors, Delivering Robust High-Frequency Performance up to 70 GHz

This microwave resistor offers excellent performance in harsh environmental conditions in a compact 02016 package size

MALVERN, Pennsylvania, USA, Shanghai, China — August 2, 2024 — Vishay Intertechnology, Inc. recently announced the launch of a new series of AEC-Q200 certified thin film chip resistors, the CHA series, which can provide high-frequency performance up to 70 GHz for automotive, aerospace and avionics, and telecommunications applications. The Vishay Sfernice CHA series uses a compact 02016 package size with resistance values ​​ranging from 10 to 500.

The newly released devices feature ultra-low internal reactance, behaving like pure resistors over a wide frequency range, with a nearly flat Z/R curve up to 70 GHz. Even after the most stressful AEC-Q200 tests, the microwave resistors maintain high-frequency stability—verified by measuring ΔR and Z/R—ensuring excellent performance in harsh environmental conditions.

The CHA series is ideal for applications such as automotive ADAS, LiDAR, connectivity, 4D radar systems, LEO satellite and space communication systems and telemetry systems, drones and RF antennas. For these applications, the devices offer a 30 V limit voltage, a 30 mW power rating at +70°C, a 100 ppm/°C temperature coefficient, and 50 ppm/°C available on request.

To reduce development time and costs, parametric data for the devices is available for electronic simulation in addition to 3D models from Ansys HFSS, Modelithics Microwave Global Models™ (PCB and pad extensions), and design kits. The resistors are RoHS-compliant, halogen-free, Vishay Green, and available in tape and reel packaging. The resistors are RoHS-compliant, halogen-free, meet Vishay Green standards, and are available in tape and reel packaging.

Samples and production quantities of the CHA series are available now, with lead times of 20 weeks.
