TIP & RING CAPACITORS

NOVACAP offers a line of low ESR surface mount

capacitors ideally

suited for “Tip & Ring” applications. These units are designed with 250

VDC rating to withstand the 52 VDC bias and 150 VRMS signal during

ring cadence. Chips are offered in X7R dielectric from 0.39µF to 1.5µF

in sizes 1812, 1825 and 2225. Product is also available in Z5U and Y5V

dielectric from 0.47µF to 1.5µF for other ring detection circuits.
