Sumida has developed a high temperature-resistant inductor for automobiles, CDRH80D65B/T150.
This inductor can be used in power circuit for automotive LED headlights as well as for ADAS including parking assistance system and camera/laser system. These applications are getting more attention in the market recently. Its resistant to high temperature is up to 150°C, which allows customers to have enough leeway in developing thermal design. It also complies with automotive reliability standard, AEC-Q200.
Key Features
- Dimension: 8.6 x 8.2 x H 6.8mm (Max.)
- Weight: 1.3g (Ref.)
- Operating temperature range: -55°C to +150°C
(Not including coil’s self temperature rise)
Applications
- Automotive ECU, Automotive LED headlights, ADAS, etc.
Production Stage
Mass Production: February 2017

*1 Measuring frequency at 100KHZ 1.0V
*2 Saturation current : DC current which becomes inductance value drop by 30% from the nominal value (at 20°C).
*3 Temperature rise current: The actual value of D.C. current when the temperature of coil becomes △T=40°C (Ta=20°C).
