Vishay introduces automotive-grade IHDF edge-wound through hole inductors

Vishay has introduced A new automotive grade IHDF edge-wound through hole inductor, the IHDF-1008BC-3A, rated up to 150 A for applications in the engine compartment environment. Using iron powder alloy core technology, with excellent inductance and saturation stability, low power consumption, excellent heat dissipation performance. In the current automotive electronic systems, the inductor plays a key role, especially in reducing electromagnetic interference, improving power handling capacity and achieving high efficiency.

In recent years, with the continuous development of automotive electronic systems and the trend of vehicle electrification, the demand for inductors is also growing. Especially in automotive applications, the performance requirements for inductors are more stringent. To meet this demand, Vishay has introduced a new automotive-grade IHDF edge-wound through hole inductor, the IHDF-1008BC-3A. This inductor has attracted a lot of attention in the automotive industry due to its excellent performance and excellent parameters.

The IHDF-1300AE-1A inductor has a rated current of up to 72A and an astounding 230A saturation current, which demonstrates its powerful current handling capability. It uses advanced ferrite core technology, making the direct current internal resistance (DCR) of the side winding coil as low as 1.1mΩ, effectively reducing energy loss, thereby improving the overall efficiency.

The IHDF-1008BC-3A uses iron-powder alloy core technology, which has excellent inductance and saturation stability. In the harsh operating temperature range of -40 C to 180 C, the inductor has low power consumption and excellent thermal performance. The direct current resistance (DCR) of the edge-wound coil is as low as 0.25 mW, minimizing losses, improving rated maximum current performance and increasing efficiency.

Compared to ferrite based solutions, the IHDF-1008BC-3A offers a 30% increase in rated and saturated current at temperatures above 125C. The inductor has a soft saturation characteristic, so the inductance value after reaching the saturation current is a predictable drop in inductance rather than a sudden drop in inductance value, and the inductance value is not affected by temperature during operation.

In addition, the IHDF-1008BC-3A operates at up to 350 V and is suitable for DC/DC converters, inverters, motor and switching noise suppression, and high-power switching power supplies in high-current, high-temperature applications. These include industrial solar systems, electric vehicle charging stations, and defense systems.

The IHDF-1008BC-3A standard has striated tin-plated pins for through-hole mounting. The device uses ER2519 iron powder core and has an external dimension of 25 mm x 20 mm x 23 mm. Vishay can customize inductors with different performance and installation modes on request. Options include aluminum copper, surface mount and press fit. In order to reduce the risk of whisker growth, the inductor adopts hot dip tin plating process. Devices comply with RoHS and Vishay green standards and are halogen-free.

Conclusion

The automotive grade IHDF edgewind through hole inductor from Vishay features low power consumption, excellent thermal performance and high stability, making it ideal for automotive electronic systems. Using iron-powder alloy core technology, it has good temperature characteristics and inductance value stability, which can meet the stringent requirements of automotive applications. With the continuous development of automobile electronization and electrification, the introduction of this inductor will provide a more efficient and reliable solution for the automotive industry.
