New Vishay Intertechnology Automotive Grade IHTH Through-Hole Inductors Deliver 156 A Saturation Current in Compact 1500 Case Size

Rhea-AI Summary

Vishay Intertechnology has launched two new Automotive Grade IHTH high current, high temperature through-hole inductors, IHTH-1500MZ-5A and IHTH-1500TZ-5A, designed for automotive applications. These compact devices operate at temperatures up to +155 °C, offering significant improvements over larger, costlier alternatives. The IHTH-1500MZ-5A supports saturation currents up to 156 A, while the IHTH-1500TZ-5A supports up to 106 A. Both models feature low DCR values, high transient current handling, and compliance with environmental standards. They are now available for sampling with lead times of eight to 10 weeks.

Designed to Replace Larger, More Expensive Solutions, Devices Offer Continuous High Temperature Operation to +155 °C

MALVERN, Pa., Oct. 25, 2021 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced two new Automotive Grade IHTH high current, high temperature through-hole inductors in the compact 1500 case size. For automotive applications, the Vishay Dale IHTH-1500MZ-5A (0.47 µH to 4.7 µH) delivers high saturation current of 156 A and very low typical DCR down to 0.19 mΩ, while the IHTH-1500TZ-5A (6.8 µH to 100 µH) offers saturation current of 106 A and typical DCR down to 1.1 mΩ. Both inductors feature continuous high temperature operation to +155 °C.

Based on IHLP^® technology, the shielded, composite construction of the devices released today enables a compact size of 38.1 mm by 38.1 mm by 19.81 mm. This allows the IHTH-1500MZ-5A and IHTH-1500TZ-5A to replace much larger and more expensive competing solutions in high current filters for 12 V / 48 V hybrid electric (HEV) and mild hybrid electric (MHEV) vehicle output converters; off-road diesel injection drivers; catalytic pulse width modulation (PWM) heaters; and electrical motors.

The IHTH-1500MZ-5A and IHTH-1500TZ-5A handle high transient current spikes without hard saturation and offer excellent temperature conductivity via their housing. RoHS-compliant, halogen-free, and Vishay Green, the devices provide high resistance to thermal shock, moisture, and mechanical shock.
