LDCR type low-voltage filter capacitor is specially used in low-voltage detuning filter system. Its metallized film adopts zinc-aluminum composite technology, adopts advanced safety protection technology, has excellent over-current and over-voltage capabilities, and uses ripple and smooth cutting technology in manufacturing. Effectively improve the thermal response and the density of the package, suppress the high inrush current, and effectively solve the problem of edge contact caused by the shrinkage effect of the edge of the winding film. Fill the electrolyte material and inert gas in a vacuum environment to improve the safety and reliability of the product. Cylindrical aluminum housing is easy to install and maintain.

Performance characteristics
.
It has a higher over-current capability. The level of the over-current index is directly related to the ability of the capacitor to withstand the inrush current and affect the service life of the capacitor;
The capacitance deviation is small and the accuracy is higher, which can ensure the resonance frequency of the filter compensation circuit to be stable and the filtering effect is good;
The power consumption is smaller, the power consumption affects the heating of the capacitor, the larger the power consumption, the higher the temperature of the capacitor, and the shorter the life;
With pressure-sensitive disconnection technology, this technology is used for each phase of the capacitor. When this capacitor cannot be used, it can be safely cut off from the circuit while maintaining good electrical insulation performance;
Adopt advanced production technology, high-frequency gold-blasted frosted tank, beautiful and corrosion-resistant, and avoid window breaking effect at the equipment management level.
