Tolerance: M: ± 20%, L: ± 15%, K: ± 10%.
Operating temperature: -30°C TO +100°C.
Inductance measured on the HP4284A LCR meter.
DCR measured on the 502BC milli-ohm meter.
Inductance drops no more than 25% at rated current applied or temperature increases ∆ t < 40°C.
Flat stack wire wound perpendicular to the center of the core.
Inductance and Current range:
a.) CSS1250S: From 0.8uH(15.0A) to 7.0uH(5.6A).
Note: RoHS compliant; for the ROHS parts, we add “-LFR” at the end of the P/N.
