Test frequency at 100kHz (2) DC resistance is measured with a Digital Multimeter TR6871 (Advantest) or equivalent. (3) Maximum allowable DC current is that which causes a 10% inductance reduction from the initial value, or coil temperature to rise by 40C, whichever is smaller.(Reference ambient temperature: 20C) 13.5 9.0 |
