📋 Description

Used product. Professional Vishay ESTAdry power electronics capacitor, DCMKP series, model identified by the marking as DCMKP 4.1-6001BR. It is a high-capacitance capacitor designed for high-voltage DC circuits, such as DC bus connection and filtering in industrial converters and drives.
MKP (metallised polypropylene) technology uses a self-healing dielectric (Self-Healing), which allows small localised breakdown points in the metallisation to be isolated. The ESTAdry version features a dry construction, without oil filling.
The design is intended for demanding industrial applications, featuring high impulse current capability, low inductance and good reliability in power electronics operation.
