Vishay Intertechnologyrecently introduced two new automotive-grade IHTH high-current and high-temperature through-hole inductor in the compact 1500 case size.
For automotive applications, the Vishay DaleIHTH-1500MZ-5A(0.47 µH to 4.7 µH) delivers a high-saturation current of 156 A and a low, typical DCR (down to 0.19 mW). TheIHTH-1500TZ-5A(6.8 µH to 100 µH) offers a saturation current of 106 A and a DCR down to 1.1 mW. Both inductors feature continuous, high-temperature operation to +155° C.
Based on IHLP technology, the shielded, composite construction of the new devices enables a compact size of 38.1 mm by 38.1 x 19.81 mm. This allows the IHTH-1500MZ-5A and IHTH-1500TZ-5A to replace larger and more expensive competing solutions in high-current filters for 12/48 V hybrid electric (HEV) and mild hybrid electric (MHEV) vehicle output converters, off-road diesel injection drivers, catalytic pulse width modulation 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, andVishay Green, the devices provide high resistance to thermal shock, moisture, and mechanical shock.
