Power Choke Coil
Series:PCC-D124H (NX)
Low profile, High power, Low loss
■ Features
● High power, high inductance (No saturation performance
limitation due to its metal dust core)
(17 A to 32 A/1.25 µH to 0.32 µH)
● Low loss realized with its low RDC (using flat wire)
● Low buzz noise due to its gap-less structure
● Surface mount, low profile type
(H)3.9 mm´(L)13.0 mm´(W)12.9 mm
■ Recommended Applications
● DC/DC converter for CPU in PCs
● Thin on-board power supply modules for servers
