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.
3 digit code: two significant digits, followed by number of zeros
eg: 394 = 390,000 pF (0.39µF)
