Aluminum electrolytic capacitor

elecond-market@elcudm.ru

+7 (34147) 2-99-89

EVAYA.673541.055 TU

Small-sized capacitors. In comparable denominations, they provide import substitution of foreign high-voltage small-sized aluminum capacitors with self-locking terminals.

Polar, sealed, isolated radial leaded and snap-in capacitors. Capacitors are suitable for application in direct current, ripple current and pulse current circuits in secondary power supplies and converter equipment. Capacitors are available in all-climate and temperate/cold climate version.
