Product Overview
The CBB21B(W)/MKP series capacitors are miniaturized, box-type metallized polypropylene film capacitors designed for wireless charging applications. Featuring a non-inductive winding structure and a self-healing capability, these capacitors offer low high-frequency loss, reduced temperature rise, and high conversion efficiency. Encased in a flame-retardant plastic shell with flame-retardant epoxy resin, they provide excellent consistency in appearance and dimensions. Ideal for DC, pulse, and low-power circuits requiring high performance, such as wireless charging and other pulsating DC circuits.
