Product Overview
The CBB21B(R)/MKPH series are box-type metallized polypropylene film capacitors designed for high-frequency DC and PFC applications in electronic equipment. They are ideal for coupling, decoupling, and filtering functions. These capacitors feature a non-inductive winding structure, small size, flame-retardant plastic casing and epoxy resin encapsulation, ensuring good dimensional consistency. They offer low loss and minimal internal temperature rise, making them suitable for switching power supplies.
