Key Features
- 2.8 µH inductance with ±20% tolerance in a compact 12565 rectangular metal-core construction for high-current power stages
- Ultra-low DCR of 5.2 mΩ (0.0052 Ω) minimizes conduction losses in high-current DC-DC converter applications up to 150 A
- Metal (FeSi alloy) core material delivers excellent saturation performance and low core loss at high switching frequencies
- Rectangular SMD package with case/size code 5150 enables automated pick-and-place assembly on standard power PCB layouts
Applications
The SPM12565XT-2R8M150 is designed for high-current synchronous buck converters and point-of-load (POL) regulators in server power supplies, GPU power delivery networks, and telecom power modules requiring 2.8 µH inductance at currents up to 150 A. Its metal FeSi core maintains inductance stability at high DC bias levels, making it ideal for multi-phase VRM designs where each phase inductor must handle large ripple currents without saturation. The compact 12565 footprint allows multiple inductors to be placed close together on dense power boards.

Frequently Asked Questions
What is the inductance value and current rating of the SPM12565XT-2R8M150?
The SPM12565XT-2R8M150 has a nominal inductance of 2.8 µH with a ±20% tolerance and is rated for a DC current of 150 A. This combination makes it well-suited for multi-phase VRM and point-of-load converter designs operating in the 500 kHz to 2 MHz switching frequency range, where high saturation current with stable inductance is critical for tight output voltage regulation.
How does the 5.2 mΩ DCR of the SPM12565XT-2R8M150 affect power converter efficiency?
With a DC resistance of only 5.2 mΩ (0.0052 Ω), the SPM12565XT-2R8M150 dissipates approximately 0.117 W at 150 A DC (I² × R = 150² × 0.0052), which represents a very small fraction of total converter losses. This ultra-low DCR is essential in server and GPU power delivery applications where inductor copper loss must be minimized to achieve 90% or higher overall converter efficiency.
What core material does the SPM12565XT-2R8M150 use and why does it matter for switching power supply designs?
The SPM12565XT-2R8M150 uses a metal (iron-silicon alloy, FeSi) core, which offers significantly higher saturation flux density than ferrite cores—typically 1.0 T to 1.5 T versus 0.3 T to 0.5 T for ferrite. This enables the inductor to maintain its rated 2.8 µH inductance at high DC bias levels close to 150 A, preventing inductance droop that would otherwise increase ripple current and degrade loop stability in high-current DC-DC converters.
What is the factory lead time for the SPM12565XT-2R8M150 and how should procurement be planned?
TDK lists the SPM12565XT-2R8M150 with a factory lead time of 15 weeks, which is typical for high-current metal-core power inductors due to their specialized winding and core processing. Procurement teams should place orders at least 16 to 18 weeks before the planned production start date and consider ordering safety stock of 10% to 20% above build quantity to buffer against lead time variability for this 150 A rated component.
