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 RDC (using flat wire)
● Low buzz noise due to its gap-less structure
● Surface mount, low profile
