Components: Small High-Frequency Inductors And Chokes Handle High Currents

Dec. 18, 2003

The LP05 high-current inductor, which features dc saturation currents from 55 to 17 A, inductance values from 100 nH to 1000 nH ±10%, and dc resistance values from 0.56 to 4.5 mΩ, works up to 1 MHz. Maximum dimensions are 10.8 by 10.2 by 5.2 in. The CS02 series common-mode chokes filter noise over 300 kHz to 100 MHz and handle RMS currents from 0.89 A up to 7.5 A. Minimum inductance values at 100 kHz range from 5.3 to 230 µH. Maximum dc resistance ranges from 5.6 to 166 mΩ. Maximum dimensions are 10.6 by 9.3 by 5.5 in. high. Inductors and chokes come in reels. Pricing for the CS02 is $0.54 each in 10,000-unit lots, and delivery is from stock to eight weeks.
