B32320I2656J011
TDK EPCOS B32320I MKP DC-link film capacitor, 65 uF at 350 V DC, compact Ø40 x 58 mm with high capacitance density.
The B32320I2656J011 is a TDK EPCOS B32320I series DC-link film capacitor rated at 350 V DC with 65 uF, in a compact cylindrical case of about 40 mm diameter by 58 mm long. The B32320I series is an extremely compact MKP DC-link capacitor for PCB mounting, with a very high capacitance density of about 0.9 uF per cubic centimetre, up to 50 percent more capacitance per volume than comparable capacitors, and a small board footprint. It is a metallized polypropylene capacitor with self-healing construction, so it does not dry out and it suits long-life and high-frequency designs. The 350 V DC rating suits a lower-voltage DC bus, and the cylindrical case mounts on a printed circuit board for a compact converter. Typical uses include the DC link of a compact motor drive, the bus of a low-voltage solar micro-inverter and the smoothing of an industrial power supply where board space is tight. The high capacitance density lets a designer meet the DC-link requirement with a small part, which simplifies the mechanical design. 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 DC-link capacitance and plan the board layout.
FAE Professional Review
The B32320I2656J011 packs a high capacitance density into a compact PCB-mount cylindrical case, which is ideal when the DC-link space is tight. The film construction and self-healing make it long-lived, and the low self-inductance helps at high frequency. Confirm the board mounting and the ripple current for your duty.

Frequently Asked Questions
What projects suit the B32320I2656J011?
It suits compact converters that need a DC-link capacitor with a small footprint, such as micro-inverters, compact drives and industrial supplies. Its high capacitance density of about 0.9 uF per cubic centimetre packs a useful capacitance into a 40 x 58 mm can.
Confirm the ripple current for your duty.
How do I mount it on the board?
The capacitor is a cylindrical PCB-mount part, so it sits on the board with the specified footprint. Keep the leads short and the layout tight to preserve the low self-inductance, and keep the capacitor clear of the hottest components.
Our FAE team can review the layout.
