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 450 V (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 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 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 7.01 A (120 Hz, +60 °C) and a service life of at least 2000 h at a maximum operating temperature of +105 °C. 

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.
