MALVERN, Pa. — Oct. 25, 2021 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced two new Automotive Grade IHTH high current, high temperature through-hole inductor 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.
