MLCCs for LED apps offer wide value range

The GR3 and RDE (X7T) lines of multilayer ceramic capacitors (MLCC) were developed specifically to overcome flickering and noise problems. The GR3 family suits reflow soldering, and the RDE series provides radially leaded insertion production capabilities. The GR3 devices come in 0805, 1206, 1210, 1812, and 2220 package sizes and are available in ratings of 250, 450, and 630 Vdc.

GR3 capacitance values range from 10 to 1,000 nF for the 250 V, 560 nF for the 450 V and 270 nF for the 630 V. The RDE is offered with the same voltage ratings, with capacitances from 33 nF to a maximum of 2.2 µF for the 250 V, 1.2 µF for the 450 V and 560 nF for the 630 V. (10-nF/250-V GR3, from $0.05 each; 33-nF/250-V RDE, from $0.15 each — 8 to 10 weeks ARO.)
