CD40D16MB is a new member to surface mount power inductor. It is featured with a compact magnetic shield structure.
By filling the winding wire with resin containing magnetic material, the magnetic shield effect and the mechanical impact strength are significant. We have also developed CD40D26MB (4.2*4.2*2.8) and CD60D28MB (6.3*6.3*3.1) with the same structure.
Key Features:
- Ferrite core construction
- Operating temperature range: -40℃～+125℃ (including coil's self temperature rise)
Applications:
DC/DC converter for CPU in notebook PC, Smartphone, LCD displays, HDDs, DVDs, SSDs, DVCs, DSCs, PDAs etc.

※1 Measuring frequency inductance at 100kHz,1V.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 30% lower than its initial value.
※3 Temperature rise current: The value of D.C. current when temperature of coil increased △T=40℃ (Ta＝20℃). (The part is mounted on PCB to test.)
