Product Overview
The Vishay Dale IHLP-4040DZ-11 series offers commercial inductors with a low DCR (DC Resistance) in a compact package. These shielded inductors are designed for high-frequency applications up to 1.0 MHz and feature ultra-low buzz noise due to their composite construction. They provide excellent temperature stability for inductance and saturation, handle high transient current spikes without saturation, and offer the lowest DCR/H in their package size. Ideal for power conversion and battery-powered devices, these inductors are suitable for a wide range of electronic 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) = 50 V.
