Applications
For VCRs, color TVs, CRTs, stereo, car radios and radio transceivers, telephone answering.
Disk drivers, personal computers and industrial, electronal products, etc.
Features
1. Design to be compact, small and light-weight, wide range of inductance.
2.Contibute to be high Q and self-resonent frequencies, tapping type that is convenient for automatic insertion, coating epoxy resin that ensure the humidity resistance to be long life
Electrical Characteristics
(1) Isat: DC current at which the inductance drops approximate 10% from its value without current;
(2) Irms: DC current that causes the temperature rise (△T ≤40°C ) from 25°C ambient.
(3) Rated Current: It is either the inductance is 10% lower than its initial value in DC saturation characteristics or temperature raise becomes △T=40℃(Ta=25℃), whichever is lower.
(4) Operating Temperature Ranges: -25～85℃. (5) Dielectric with standing voltage:250V AC r.m.s.
Test Equipments
(1) Inductance(L): HP 4284A/HM 9481/CD 1063/HP 4291A;
(2) Q: HP 4284A/HM 9481;
(3) DCR: CH 502A/CH 502BC;
(4) SRF: HM 9461;
(5) Rated Current/Isat./Irms.: HP 4284+HP 4284A/CD 1068+CD 1320. Test Condition: at 25℃,75%H.
