Power Choke Coil

Series:

PCC-D124H (NX1)

Low proﬁle, High power, Low loss

■ Features

● High power, high inductance (No saturation performance

limitation due to metal dust core)

(17 A to 32 A/1.25 μH to 0.32 μH)

● Low loss due to low R_DC(using ﬂat wire)

● Low buzz noise due to its gap-less structure

● Surface mount, low proﬁle

(H) 3.9 mm (L)13.0 mm (W)12.9 mm

● RoHS compliant

■ Recommended Applications

● DC-DC converter for CPU in PCs

● Thin on-board power supply modules for servers

■ Standard Packing Quantity

● 500 pcs./Reel
