Silicon steel C-core and clip with a range of coils for use as inductors and transformers. The approximate inductance values, with and without a complete C-core, are shown in the table below. Current ratings are based on 150A per square cm. The coils will run hot, but will not be damaged by short-term currents of up to twice the stated value.

No. of Turns: 120 +120

Air-core 1.5mH
Wire 1.0mm
Max Current 1.02A
