EPCOS / TDK B43657 Snap-In Aluminum Electrolytic Capacitors

EPCOS / TDK B43657 Snap-In Aluminum Electrolytic Capacitors offer high reliability, high ripple current capability, and extremely high capacitance density. These ultra-compact snap-in modules achieve a service life of at least 2000 hours at a maximum operating temperature of +105°C and cover a rated voltage range from 450V_DC to 475V_DC with capacitance values from 120µF to 1250μF. The B43657 series also features up to 8.54A ripple current capability (120Hz, +60°C) and case sizes ranging from only 22mm x 25mm to 35mm x 60mm (D x H). EPCOS / TDK B43657 Snap-In Aluminum Electrolytic Capacitors are RoHS compatible and operate in a -40°C to +105°C temperature range. Applications include high-end switching power supplies, power supplies for industrial and telecommunications, uninterruptible power supply (UPS) systems, photovoltaic inverters, and frequency converters.

Accurate lifetime calculation under application-specific conditions is quick and easy with the TDK Online AlCap Tool.
