TDK offers snap-in capacitors with increased compactness for general-purpose applications

TDK Corporation announces the new EPCOS B43659 series of snap-in aluminum electrolytic capacitors. This is the next generation of ultra-compact general-purpose components for voltages of 450V (DC) featuring an extremely high CV product. It provides the same features and serves the same applications as the previous series; however, the B43659 is much more compact. In case sizes of only 22mm x 25mm to 35mm x 50mm (D x H), these components achieve capacitances ranging from 140µF to 1030µF. In addition to the standard versions with 2 terminals, versions with 3 terminals are also available to ensure correct installation.

Essential performance features include a high ripple current capability of up to 7.01A (120Hz, +60°C) and a service life of at least 2000h at a maximum operating temperature of +105°C. Accurate lifetime calculation under application-specific conditions is quick and easy with the web-based AlCap 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 (more info).
