This microwave resistor adopts a compact 02016 package size and has excellent performance under harsh environmental conditions
Recently, Vishay Intertechnology, Inc. (NYSE stock code: VSH) 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, aviation electronics, and telecommunications applications. The Vishay Sfernice CHA series adopts a compact 02016 package size, with resistance values ranging from 10 W to 500 W.
The newly released device has ultra-low internal reactance and performs similarly to a pure resistor over a wide frequency range. The Z/R curve is almost flat, and the frequency can reach 70 GHz. Even after the highest stress AEC-Q200 test, the microwave resistor maintains high-frequency stability - verified by measuring Δ R and Z/R - ensuring excellent performance under harsh environmental conditions.
The CHA series is highly suitable 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, these devices provide a maximum voltage of 30 V, a rated power of 30 mW at+70 ° C, a temperature coefficient of ± 100 ppm/° C, and can provide ± 50 ppm/° C as required.
To shorten development time and reduce costs, in addition to Ansys HFSS's 3D models, Modelithics Microwave Global Models (PCB and pad extensions), and design kits, device parameter data can also be used for electronic simulation. These resistors comply with RoHS standards, do not contain halogens, are Vishay Green, and are packaged in a tape roll. The resistor complies with RoHS standards, is halogen-free, meets Vishay green standards, and is packaged in tape and reel.
The CHA series can now provide samples and has achieved mass production, with an ordering cycle of 20 weeks.
