Vishay Intertechnology has released 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 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.
