(Use for power rails and switching regulators.)
Pinout
Function: SPM6550T-4R7M is a 4.7 µH surface-mount power inductor used for energy storage and filtering in DC‑DC converters and power‑supply filters. It provides inductance for switching regulators, high current handling and low DCR to reduce losses and ripple.
Manufacturer
What kind of company: Coilcraft is a U.S.-based electronics manufacturer specializing in inductors and magnetic components (power inductors, RF inductors, transformers and related passive components) for power-management and RF applications.
Application
- CPU/GPU and chipset VRMs in desktops and notebooks
- Point‑of‑load/DC‑DC converter stages in servers and memory modules
- Telecom/data‑communication power rails and small industrial PSUs
- Automotive power management (infotainment, ECUs, sensors)
- Industrial drives and general consumer electronics power supplies
Also suitable as EMI/LC filter chokes in buck/boost/SEPIC topologies.
