Choke Coils
Power Choke Coil
Series:
PCC-D124H (NX1)
Low pro le, 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 H to 0.32 H)
Low loss due to low R (using at wire)
DC
Low buzz noise due to its gap-less structure
Surface mount, low pro le
