Operating temperature: -25ºC TO +85ºC. Inductance measured on the HP4284A or HP4285A LCR meter. DCR measured on the 502BC milli-ohm meter. Inductance drops no more than 35% at rated current applied or temperature rises ∆ t < 40ºC. Very low profile used for DC-DC converter, LCD driver power supply, Notebook PC, and ElectroLuminescent backlight for Digital Video Camera, Digital Still Camera, GPS, PDC etc. Portable equipment. Inductance range: CST0413H-series From 220uH(110 mA) to 560uH(55 mA). D. Note: RoHS compliant; for the ROHS parts, we add “-LFR” at the end of the P/N. SMD Power Choke: P/N CST0413H-series Rev.
