SD Series High Power Density, Low Profile, Shielded Inductors

Transcript

1 Description Six sizes of shielded drum core inductors with low profiles (as low as.mm) and high power density Inductance range from.47uh to uh Current range from 6. to 88 mps Ferrite shielded, low EMI Ferrite core material pplications Digital cameras, CD players, cellular phones, and PDs PCMCI cards GPS systems Environmental Data Storage temperature range: - C to +5 C Operating ambient temperature range: - C to +85 C (range is application specific). Temperature rise is approximately C at rated rms current Solder reflow temperature: + C max. for seconds max.
