FREQ RESISTANCE
1. Inductance is measure with a LCR meter 4284A( Agilent) or equivalent
2. Maximum allowable DC current is that which causes a 10% inductance reduction form the initial
value,or coil temperature to rise by 20
℃
, whichever is smaller.(Reference ambient temperature
20
℃
)
3. Self-resonant frequency is measured with a network analyzer model 3577*, MS560J(Anritsu),or
equivalent.
4. DC resistance is measured with a digital multimeter TR6871(Advantest) or equivalent.
5. Self-resonant frequency is for reference only. * Agilent Technologies
