Product Overview
The SNR6045 Series Magnetic Resin Shielded SMD Power Inductors are automatic assembly constructed power inductors featuring magnetic-resin shielding for ultra-low buzz noise. They offer large current handling, low DC resistance, and excellent shock resistance due to metallization on the ferrite core. The closed magnetic circuit design minimizes leakage flux and EMI, making them space-saving and power-efficient. These inductors are widely used in LED backlights, flat-screen TVs, notebooks, desktops, servers, graphics cards, portable gaming devices, personal navigation systems, multimedia devices, automotive systems, telecommunication base stations, and DC-DC converters. They comply with RoHS, Halogen Free, and REACH standards.

Definitions
- Saturation Current: DC current at which inductance drops 30% from its value without current.
- Temperature Rise Current: The actual value of DC current when the temperature rise is T 40 (Ta=25).
- Rated DC Current: The lesser value between Isat and Irms.
Important Notes on Thermal Design
Circuit design, component placement, PCB trace size and thickness, airflow, and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
