Vishay AEC-Q200 qualified thin film chip resistors

Offered in the compact 02016 case size, the Vishay Sfernice CHA series is available in a wide range of resistance values from 10 Ω to 500 Ω.

The devices released today 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 70 GHz. The 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.

The CHA series is ideal for automotive ADAS, LIDAR, connectivity, and 4D radar systems; LEO satellites and space communication systems; military guidance and telemetry systems; drones; and RF antennas. For these applications, the devices provide a limiting voltage of 30 V, rated power of 30 mW at +70 °C, and a temperature coefficient of ± 100 ppm/°C, with ± 50 ppm/°C available on request.

To reduce development time and costs, the devices' 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. RoHS-compliant, halogen-free, and Vishay Green, the resistors are offered in tape and reel packaging.

Samples and production quantities of the CHA series are available now, with lead times of 20 weeks.
