SLV1211 Series

TLVR Shielded Power Inductors

The SLV1211 Series Trans-Inductor Voltage Regulator (TLVR) inductors are designed for use in voltage regulator modules (VRMs) and point-of-load (PoL) converters. With a compact 12 × 6 mm footprint and high power density, these inductors deliver efficient performance in space-constrained designs. This series provides low DCR, tight magnetic coupling, and excellent thermal performance, enabling fast transient response and supporting current ratings up to 150 A. The SLV1211 is well-suited for next-generation CPUs, GPUs, ASICs, and SoCs used in servers, data centers, and various power applications.

Notes

Inductance at 100 kHz, 0.1 Vrms, 0 Adc.
DCR is measured on a micro-ohmmeter at points indicated in the diagram below.
Isat: DC current that causes a 20% (typ) inductance drop from its value without current. Temperature derating curves.
Irms: Current applied to the primary winding (pins 1 – 4) that causes the specified temperature rise from a 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, air flow, and proximity to other components. Therefore temperature rise should be verified in application conditions. Temperature derating curves.
