Vishay’s range of IHTH high-current, high-temperature, through-hole inductors including the AEC-Q200-qualified IHTH-0750IZ-5A and IHTH-1125KZ-5A are on sale at Farnell element14. These feature an operating temperature range from -55 °C to +155 °C, high rated currents up to 125 A, and a wide range of inductance values from 0.47 µH to 100 µH. They are available in 0750 and 1125 sizes.

With a frequency range up to 10 MHz for some values, the devices are ideal for voltage regulator modules (VRM) and DC/DC converters.

The IHTH-0750IZ-5A and IHTH-1125KZ-5A are designed for a variety of high-temperature automotive applications, including engine and transmission control units, diesel injection drivers, LED drivers, HID lighting, and noise suppression for motors in windshield wipers, power seats and mirrors, and heating and ventilation blowers.

These inductors handle high transient current spikes without hard saturation and are packaged in an RoHS-compliant, 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels.

The IHTH-0750IZ-5A and IHTH-1125KZ-5A offer high resistance to thermal shock, moisture, mechanical shock and vibration. They are halogen-free and conform to Vishay “Green” standards.
