Vishay Intertechnology, Inc. has expanded its CHA Series of thin-film chip resistors with new devices in the 0402 case size. These AEC-Q200-qualified CHA0402 resistors are available with a wide range of resistance values from 10 Ω to 500 Ω, providing high frequency performance up to 50 GHz for automotive, telecom, medical, space, avionics, and military applications.

The CHA series resistors are available in the 02016 and 0402 case sizes. They offer very low internal reactance and exhibit behavior close to a pure resistor over their large frequency range, with a nearly flat Z/R curve to 70 GHz and 50 GHz, respectively, the company said.
These microwave resistors maintain their high frequency stability even after the most stressful AEC-Q200 tests — validated by their ΔR and Z/R measurements — guaranteeing high performance under harsh environmental conditions, Vishay said.
The thin-film chip resistors can be used in a wide range of harsh environments. They provide limiting voltage of 37 V, rated power of 300 mW at 70 °C, and a temperature coefficient of ± 100 ppm/°C, with ± 50 ppm/°C available on request.
Applications include automotive ADAS, LIDAR, connectivity, and 4D radar systems; LEO satellites and space communication systems; X-ray, MRI, and CAT scan machines; 5G / 6G telecommunications equipment, base stations, and repeaters; military guidance and telemetry systems; drones; and RF antennas.
These resistors are RoHS-compliant, halogen-free, and Vishay Green, and are offered in waffle pack and tape and reel packaging. S-parameter data is available for electronic simulation, in addition to 3D models for Ansys HFSS, Modelithics Microwave Global Models (PCB and pad-scalable), and design kits. Samples and production quantities are available now, with lead times of 20 weeks.
