The capacitor expertise gives effectivity and enhanced security for high-voltage purposes, making it appropriate for upgrading varied digital units.
TDK Company has launched the EPCOS B43659 capacitor sequence, the newest in snap-in aluminium electrolytic sequence. These elements are designed for 450 V (DC) purposes and have a excessive CV product. They maintain the functionalities and purposes of their predecessors however have smaller dimensions, starting from 22 mm x 25 mm to 35 mm x 50 mm (D x H), with capacitance values between 140 µF and 1030 µF. Each customary two-terminal variations and three-terminal variations can be found for set up accuracy.
Key efficiency options embrace a most ripple present capability of seven.01 A at 120 Hz and +60 °C, with a lifespan of at the very least 2000 hours at temperatures as much as +105 °C. These capacitors are appropriate for varied purposes, together with switched-mode energy provides, frequency converters, uninterruptible energy provides (UPS), medical gear, and photo voltaic inverters.
The newly designed capacitors function an ultra-compact construction, with diameters starting from 22 to 35 mm and lengths as much as 100 mm. They’re engineered to maximise power density inside a voltage vary of 400 to 500 V DC, providing a 20% enhance in capacitance in comparison with earlier fashions. This enhancement contributes to their excessive power density and excessive ripple present functionality.
When it comes to building, these capacitors profit from in-house developed anode foils, that are outfitted with long-life oxide to extend their floor space considerably. This design not solely improves efficiency but in addition ensures robustness. Moreover, they embrace an overload safety function via a stress reduction system positioned on the bottom, enhancing their security and sturdiness.
The capacitor’s building options an aluminium case insulated with a PET sleeve; nonetheless, the underside of the can lacks an insulation sheet. It consists of snap-in solder pins that safe the part on the PC board, and the minus pole is marked on a shrinking sleeve however will not be insulated from the case. For security, overload safety is offered by a stress reduction system on the bottom. Moreover, these capacitors will be requested with lengths as much as 100 mm to accommodate particular design wants.
