CMLW5040S2R2MST
Package:
SMD,5x5mm
Key Attributes
Model Number:
CMLW5040S2R2MST
Product Description
Product Overview
The CMLW5040S Series is a wire-wound SMD power inductor featuring magnetic-resin shielding for ultra-low buzz noise. Its metallization on the ferrite core ensures excellent shock resistance and durability, while the closed magnetic circuit design minimizes leakage flux and EMI. These inductors offer a 30% higher current rating than conventional inductors of equal size, saving PCB real estate and power.

Applications
- LED Lighting
- Mobile devices with multifunction (e.g., color TV, camera)
- Flat-screen TVs, blue-ray disc recorders, set-top boxes
- Notebooks, desktop computers, servers, graphic cards
- Portable gaming devices, personal navigation systems, personal multimedia devices
- Automotive systems
- Telecomm base stations
Operating Conditions
- Operating temperature range (Including self-heating): -40 ~ +125
- Storage temperature range (packaging conditions): -10~+40 and RH 70% (Max.)
Notes
- All test data is referenced to 20C ambient.
- Rated current: Isat or Irms, whichever is smaller.
- Isat: DC current at which the inductance drops approximate 30% from its value without current.
- Irms: DC current that causes the temperature rise (T =40C) from 20C ambient.
Standard Packing
- Quantity: 1500 pcs/reel
