TDK-EPC, a group company of TDK Corporation, has developed snap-in aluminum electrolytic capacitors from EPCOS that enable optimal contact to heat sinks. This permits link circuit capacitors to be efficiently cooled, significantly increasing their ripple current capability and operating life. As a result, the new capacitors are especially suited for applications in frequency converters and professional power supplies that have very high ripple current loads and offer the possibility of base cooling.
These snap-in capacitors for base cooling are available in the B43540* (85 °C), B43543* (105 °C), B43505* (105 °C) series for dimensions of 30 x 35 mm to 35 x 55 mm. They are equipped as standard with a PET shrunk sleeve as insulation and are RoHS-compatible. If required, they can also be supplied without insulation or with mounted thermal pads.
