Vishay Intertechnology Introduces New IHDM Automotive Grade Inductors with Stable Inductance and Saturation at High Temperatures

Vishay Intertechnology has introduced two new IHDM Automotive Grade edge-wound, through-hole inductors with stable inductance and saturation at temperatures up to +180 °C. The devices have a powdered iron alloy core technology and provide low DCR down to 0.22 mΩ, making them ideal for high current, high temperature power applications in internal combustion, hybrid, and full-electric vehicles. The inductors are available with customizable performance options and mounting styles.

Vishay Intertechnology, Inc. (NYSE: VSH) has recently unveiled two new inductors designed for automotive applications, the IHDM-1107BBEV-2A and IHDM-1107BBEV-3A. These edge-wound, through-hole inductors feature powdered iron alloy core technology and offer stable inductance and saturation at temperatures ranging from -40°C to +180°C. The devices are particularly notable for their low DCR (Direct Current Resistance), which is as low as 0.22 mΩ, significantly reducing power losses and enhancing efficiency.

The new inductors boast a 30% higher rated current and 30% higher saturation current compared to competing ferrite-based solutions, particularly at +125°C. This performance is facilitated by the soft saturation current up to 422 A, which provides a predictable inductance decrease with increasing current, independent of temperature. The inductors are AEC-Q200 qualified, making them suitable for high current, high temperature power applications such as DC/DC converters, inverters, and on-board chargers in internal combustion, hybrid, and full-electric vehicles.

Key features of the IHDM-1107BBEV-2A and IHDM-1107BBEV-3A include a high isolation voltage rating up to 350 V and customizable performance options, including inductance, DCR, rated current, and voltage rating. These inductors are available in various mounting styles, including through-hole, surface-mount, and press-fit, and are designed to minimize the risk of whisker growth with hot-dipped tin plating. The devices are also RoHS-compliant, halogen-free, and Vishay Green, aligning with environmental standards.

The IHDM-1107BBEV-2A and IHDM-1107BBEV-3A are now available in samples and production quantities, with a lead time of 14 weeks. Vishay Intertechnology, a Fortune 1000 Company listed on the NYSE, manufactures a wide range of discrete semiconductors and passive electronic components essential to innovative designs across various markets, including automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical.
