Core Viewpoint - Vishay Intertechnology, Inc. has expanded its CHA series of AEC-Q200 qualified thin film chip resistors, introducing new devices in the 0402 case size, which deliver stable high frequency performance up to 50 GHz under harsh environmental conditions [1][2]. Product Features - The CHA0402 resistors are available with resistance values ranging from 10 Ω to 500 Ω and maintain high frequency stability even after rigorous AEC-Q200 tests, validated by their ΔR and Z/R measurements [1][2]. - These resistors exhibit very low internal reactance and a nearly flat Z/R curve up to 50 GHz, making them suitable for a wide range of applications [2]. Applications - The CHA series is ideal for various applications including automotive ADAS, LIDAR, connectivity, 4D radar systems, LEO satellites, space communication systems, medical imaging machines, and 5G/6G telecommunications equipment [3]. Technical Specifications - CHA0402 resistors have a limiting voltage of 37 V, rated power of 300 mW at +70 °C, and a temperature coefficient of ± 100 ppm/°C, with an option for ± 50 ppm/°C available upon request [3]. Development Support - To facilitate development, S-parameter data for electronic simulation and 3D models for Ansys® HFSS™ and Modelithics Microwave Global Models™ are provided, along with design kits [4]. Compliance and Availability - The resistors are RoHS-compliant, halogen-free, and Vishay Green, available in waffle pack and tape and reel packaging, with samples and production quantities currently available and lead times of 20 weeks [4]. Company Overview - Vishay Intertechnology, Inc. is a leading manufacturer of discrete semiconductors and passive electronic components, serving various markets including automotive, industrial, telecommunications, and medical [5].
