Product Description
Product Overview
The Vishay Dale IHLP Commercial Inductors, High Saturation Series are designed for high current applications with a frequency range up to 5.0 MHz. These inductors feature shielded construction, lowest DCR/H in their package size, and ultra-low buzz noise due to their composite construction. They are capable of handling high transient current spikes without saturation, making them ideal for various power conversion and electronic device applications.

Applications
- PDA / notebook / desktop / server applications
- High current POL converters
- Low profile, high current power supplies
- Battery powered devices
- DC/DC converters in distributed power systems
- DC/DC converter for field programmable gate array (FPGA)
Notes
- All test data is referenced to 25 C ambient.
- Operating temperature range: -55 C to +125 C.
- The part temperature (ambient + temp. rise) should not exceed 125 C under worst-case operating conditions.
- Rated operating voltage (across inductor) = 75 V.
- (1) DC current (A) that will cause an approximate T of 40 C.
- (2) DC current (A) that will cause L0 to drop approximately 20 %.
