Tolerance: M: ± 20%, L: ± 15%, K: ± 10%. Electrical specifications at +25ºC. Operating temperature: -25ºC TO +85ºC. Inductance measured using the HP4284A LCR meter. DCR measured using the 502BC milli-ohm meter. Inductance drops no more than 10% (Typ.) at rated I sat. Temperature rises ∆ t < 40ºC (Typical) at rated I rms. 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. SMD Power Choke: P/N CSN042A-series Rev.: C Jan. 01, 2006.
