AEC-Q200 qualified thin film chip resistors now available in 0402 case size

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

Now available in the 02016 and 0402 case sizes, the series devices offer very low internal reactance and exhibit behaviour close to a pure resistor over their large frequency range, with a nearly flat Z/R curve to 70GHz and 50GHz, respectively. The microwave resistors maintain their high-frequency stability even after the most rigorous AEC-Q200 tests—validated by their ΔR and Z/R measurements—ensuring high performance under harsh environmental conditions.

The CHA series is ideal for 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. For these applications, the CHA0402 resistors provide limiting voltage of 37V, rated power of 300mW at +70C, and a temperature coefficient of ±100ppm/C, with ±50ppm/C available on request.

To reduce development time and costs, the devices' S-parameter data is obtainable for electronic simulation, in addition to 3D models for Ansys HFSS, Modelithics Microwave Global Models (PCB and pad-scalable), and design kits. RoHS-compliant, halogen-free, and Vishay Green, the resistors are supplied in waffle pack and tape-and-reel packaging.
