HP4284A,CH11025,CH3302,CH1320,CH1320S

LCR Meter.

DCR

CH16502,Agilent33420A Micro-Ohm Meter.

Saturation Current (Isat)

△L≦30% typical.

Saturation DC Current (Isat) will cause L0

to drop △L(%)(keep quickly).

Heat Rated Current (Irms)

Approximately △T≦40℃

Heat Rated Current (Irms) will cause the coil temperature rise

△T(℃) without core loss.

1.Applied the allowed DC current(keep 1 min.).

2.Temperature measured by digital surface thermometer
