Measuring Freq. (L)
CDH53
2.2µH – 4.7µH (7.96MHz), 10µH – 220µH (1kHz)
Tolerance of Inductance
CDH53
2.2µH – 4.7µH ± 20% (M), 10µH – 12µH ± 15% (L), 15µH – 56µH ± 10% (K), 68µH – 220µH ± 5% (J)
Rated D.C. Current
This indicates the value of current when the inductance is 10% lower than its initial value at D.C. superimposition or D.C. current when at t=40°C, whichever is lower. (Ta=20°C)
