The 0402 resistors work up to 50 GHz, stay stable in conditions, and are used in cars, medical devices, space systems, and networks.
Vishay Intertechnology has expanded its CHA Series of AEC-Q200 qualified thin film chip resistors by adding new devices in the compact 0402 case size. These resistors cover a resistance range from 10 Ω to 500 Ω and are designed for high-frequency performance up to 50 GHz. The series is already available in the 02016 size, which supports up to 70 GHz, offering flexibility for space-constrained and high-speed applications.
CHA resistors are engineered for low internal reactance, ensuring nearly ideal resistor behavior across wide frequency bands. Their flat Z/R curve—up to 70 GHz for 02016 and 50 GHz for 0402—means they maintain stable performance across the signal spectrum. Even after undergoing the full set of AEC-Q200 qualification tests, including temperature cycling and mechanical stress, these resistors show minimal resistance drift and remain consistent in their impedance characteristics.
These properties make the CHA series well suited for a wide range of advanced systems. Applications include automotive ADAS, LIDAR, connectivity modules, and 4D radar; medical imaging systems like X-ray, MRI, and CT machines; low Earth orbit (LEO) satellites and space communication platforms; 5G/6G base stations, repeaters, and RF front ends; as well as military guidance, telemetry, drones, and RF antennas. In the 0402 format, the resistors offer a limiting voltage of 37 V, a rated power of 300 mW at +70 °C, and a temperature coefficient of ±100 ppm/°C, with ±50 ppm/°C available on request.
To support faster and more accurate design, Vishay provides S-parameter data for circuit simulation, 3D models compatible with Ansys HFSS, and scalable design models through Modelithics Microwave Global Models. These tools help engineers reduce development time and ensure predictable behavior in RF designs. The CHA series resistors are RoHS-compliant, halogen-free, and Vishay Green, and are available in both waffle pack and tape-and-reel packaging for flexible production needs.
