CMLW4018S1R5MST
Package:
SMD,4x4mm
Key Attributes
Model Number:
CMLW4018S1R5MST
Product Description
Product Overview
The CMLW4018S Series is a wire-wound SMD power inductor featuring magnetic-resin shielded construction for ultra-low buzz noise. Its metallization on the ferrite core provides excellent shock resistance and damage-free 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.

Part Numbering System
Example: CMLW4018S100MST
- (1) Series Type: CMLW
- (2) Dimension: 4018S
- (3) Material Code: (Not specified in detail)
- (4) Inductance: 100 = 10H
- (5) Inductance Tolerance: M = 20%
- (6) Company Code: S (Not specified in detail)
- (7) Packaging: T = Tape Carrier Package
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 approximately 30% from its value without current.
- Irms: DC current that causes the temperature rise (T =40C) from 20C ambient.
