Low DCR Shielded Composite Inductor VISHAY IHLP1212ABERR47M11 for DC DC Converters and Power Supplies
Vishay IHLP Commercial Inductors, Low DCR Series
The Vishay IHLP-1212AB-11 series offers shielded construction for excellent DC/DC energy storage up to 1 MHz to 2 MHz and filter inductor applications up to SRF. These inductors feature the lowest DCR/H in their package size, handle high transient current spikes without saturation, and exhibit ultra-low buzz noise due to their composite construction. They are ideal for 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, and DC/DC converters for Field Programmable Gate Arrays (FPGAs).

Notes:
(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 %.
Operating temperature range: -55 C to +125 C. Part temperature (ambient + temp. rise) should not exceed 125 C under worst case operating conditions.
