June 30, 2025 /SemiMedia/ — Vishay Intertechnology has introduced a new 0402 case size variant to its CHA series of AEC-Q200 qualified thin film chip resistors, delivering reliable high-frequency performance up to 50 GHz. The new devices target demanding applications across automotive, telecom, aerospace, medical, and defense markets.

The CHA0402 resistors feature a resistance range from 10 Ω to 500 Ω and exhibit near-ideal resistor behavior over a broad frequency spectrum. In both 0201 and 0402 packages, the series delivers flat Z/R characteristics up to 70 GHz and 50 GHz, respectively. The resistors also maintain electrical stability after stringent AEC-Q200 stress tests, confirming their suitability for harsh environments.

Key use cases include ADAS, LIDAR, 4D radar, low-earth-orbit (LEO) satellites, 5G/6G base stations, MRI and CT scanners, RF antennas, and military telemetry. The CHA0402 model supports 300 mW rated power at +70 °C, a 37 V limiting voltage, and a temperature coefficient of ±100 ppm/°C (optional ±50 ppm/°C).

To accelerate development cycles, Vishay offers S-parameter files and 3D models compatible with Ansys HFSS™ and Modelithics PCB/pad-scalable tools. The components are RoHS-compliant, halogen-free, and Vishay Green, with packaging options in tape and reel or waffle pack. Samples and production quantities are available now, with standard lead times of 20 weeks.
