G F G Land Pattern Tolerance: M: ± 20%. Operating temperature: -25ºC TO +85ºC Electrical specifications at +25ºC. Inductance measured on the HP4284A LCR meter. DCR measured on the 502BC milli-ohm meter. Temperature rises ∆ t < 15ºC (Typical) at rated I rms. Average maximum allowable current: CST042C series are designed for current spikes as high as 2 times the current rated. Inductance range: CST 042C series from 1.0uH(2.00A) to 1000uH(0.08A). Note: RoHS compliant; for the ROHS parts, we add “-LFR” at the end of the P/N. SMD Power Choke: P/N CST042C-series Rev. A Jan. 01 2006. Page: 1 of 1 Frontier Electronics Corp. 667 E.
