TDK Corporation (TSE:6762) presents the new EPCOS B43657* aluminum electrolytic capacitor series with snap-in terminals. The capacitors achieve a service life of at least 2000 h at a maximum operating temperature of 105 °C and cover a rated voltage range from 450 V DC to 475 V DC with capacitance values from 120 µF to 1250 μF. An important performance feature is their high ripple current capability of up to 8.54 A (120 Hz, 60 °C). Accurate lifetime calculation under application-specific conditions is quick and easy with the online AlCap Tool. (www.tdk-electronics.tdk.com/en/alcap_tool).
Particularly noteworthy is the extremely high capacitance density of the ultra-compact capacitors with case sizes from only 22 mm x 25 mm to 35 mm x 60 mm (D x H).
Due to their high reliability, these RoHS-compatible capacitors are optimal for use in high-end switched-mode power supplies and power supplies for industrial and telecommunications applications. In addition, they are well-suited for UPS systems, photovoltaic inverters and frequency converters.
