B43659 Snap-in Capacitors

TDK Corporation/EPCOS' B43659 series of snap-in aluminum electrolytic capacitors is the next generation of ultra-compact general-purpose components for voltages of 450 V_DC featuring an extremely high CV product. It provides the same features and serves the same applications as the previous series but the B43659 is much more compact. In case sizes of only 22 mm x 25 mm to 35 mm x 50 mm (D x H), these components achieve capacitances ranging from 140 µF to 1030 µF. In addition to the standard versions with two terminals, versions with three terminals are also available to ensure correct installation.

Essential performance features include a high ripple current capability of up to 7.01 A (120 Hz, +60°C) and a service life of at least 2,000 h at a maximum operating temperature of +105°C. Accurate lifetime calculation under application-specific conditions is quick and easy with the web-based AICap Tool.

Due to their high reliability and compact size, these RoHS-compliant aluminum electrolytic capacitors can be used in a wide range of applications, such as switched-mode power supplies, frequency converters, uninterruptible power supplies (UPS), medical equipment, and solar inverters.
