TDK EPCOS IGBT Snubber Capacitor Distributor | Low-Inductance MKP
Genuine TDK EPCOS low-inductance MKP snubber capacitors, 850 V to 2000 V with ESL down to 6 nH for IGBT overvoltage protection.
TDK EPCOS IGBT Snubber Overview
BeiLuo supplies genuine TDK EPCOS snubber film capacitors, low-inductance metallized polypropylene (MKP) parts that protect IGBT modules against the voltage peaks produced when a high current is switched off across a DC link. A snubber capacitor sits close to the IGBT and absorbs the energy of the commutation-loop inductance, limiting the collector-emitter overshoot and keeping the device within its safe operating area. TDK EPCOS's snubber families include the B32656S to B32658S series, a range tailored to IGBT modules from 850 V to 2000 V with capacitances from 68 nF to 5.6 uF, extremely low ESL values as low as 6 nH and high pulse strength, available in many terminal configurations with hole spacings from 19.5 mm to 63 mm. The B32652 and B32654 MKP snubber and PFC series cover lower voltages such as 1000 V to 2000 V in compact leaded formats. These capacitors are used in frequency converters, motor drives, traction converters, welding inverters, induction heating and any power stage where a fast switch demands protection against overvoltage. The low ESL and high pulse strength make them effective at the high dV/dt of modern IGBTs and wide-bandgap devices. Every capacitor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you size the snubber capacitance, choose the terminal configuration and plan the low-inductance layout.

Frequently Asked Questions
How do I read the snubber capacitor table?
Capacitance and Voltage set the snubber energy and the voltage class, ESL tells you how well the part limits overshoot at high dV/dt, and Construction confirms the MKP type. The terminal configuration must match your IGBT module.
Lower ESL means better protection at fast switching.
Why does a snubber capacitor help an IGBT?
When an IGBT switches off a high current, the energy stored in the commutation-loop inductance produces a voltage spike across the device. A snubber capacitor close to the IGBT absorbs that energy and limits the spike, keeping the device within its safe operating area.
Low ESL and a tight layout make it effective.
Why does ESL matter so much in a snubber?
The snubber must respond in the nanoseconds of a fast switching edge, so its equivalent series inductance sets how quickly it can absorb the spike. Lower ESL means the snubber acts sooner and the overshoot is smaller, which is why TDK EPCOS offers parts in the single-digit nanohenry range.
Keep the snubber loop short for the best result.
