C. Features:
1. Tolerance: M: ± 20%, L: ± 15%, K: ± 10%.
2. Electrical specifications at +25ºC.
3. Operating temperature: -25ºC TO +85ºC.
4. Inductance measured using the HP4284A LCR meter.
5. DCR measured using the 502BC milli-ohm meter.
6. Inductance drops no more than 10% (Typ.) at rated I sat.
7. Temperature rises ∆ t < 40ºC (Typical) at rated I rms.
8. The coil and core is enclosed in a flattop ceramic case.
Note: RoHS compliant; for the ROHS parts, we add “-LFR” at the end of the P/N.
