SN8S-40P2

Overview

The KEMET SN8S-40P2 is a high-performance, low-profile surface-mount shielded power inductor designed for demanding DC-DC converter applications. It features a compact footprint with a maximum height of 2.5mm, facilitating dense PCB layouts. The component utilizes a sintered ferrite core and a silver-plated copper wire winding to ensure robust electrical performance and thermal stability. With a nominal inductance of 4.0µH and a saturation current rating up to 13A, it provides efficient energy storage and filtering capabilities. The shielded construction minimizes electromagnetic interference (EMI) coupling to surrounding components, making it suitable for sensitive electronic environments.

Feature Summary

• Shielded magnetic structure reduces electromagnetic interference and stray flux fields.
• Low-profile design enables space-constrained surface-mount assembly.
• High saturation current capability supports peak load demands in power conversion circuits.

Applications

• Point-of-load (POL) DC-DC converters
• Server and data center power distribution modules
• Telecommunications equipment power supplies

Procurement Notes

Verify the complete part number against official KEMET documentation to confirm specific tolerance and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the component's physical dimensions and terminal configuration. Cross-reference lead finish specifications if solderability requirements are critical for the manufacturing process.

Selection Notes

Select this component based on required inductance values and current handling capabilities within the target power supply topology. Evaluate the thermal derating curves to ensure operation within safe temperature limits under maximum load conditions. Consider the physical size constraints of the PCB layout when choosing between available package options in the series.

Part Context
