Vishay Dale IHLP Commercial Inductors, High Saturation Series
The Vishay Dale IHLP-4040DZ-01 series offers high-performance commercial inductors designed for demanding applications. These inductors feature shielded construction, a wide frequency range up to 5.0 MHz, and ultra-low buzz noise due to their composite construction. They are engineered to handle high transient current spikes without saturation and provide the lowest DCR/H in their package size. Ideal for power supplies, DC/DC converters, and portable electronic devices, these inductors contribute to efficient and reliable circuit designs.

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 %.
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)
