The 1825PC824KAT1A is a surface-mount (SMT) Multilayer Ceramic Chip Capacitor with Ni and Sn plated terminations. The AVX tip & ring or ring detector multilayer ceramic chip capacitor is designed as a standard telecom filter to block -48VDC telephone line voltage and pass subscriber's AC signal pulse (16 to 25Hz, 70 to 90Vrms). The ringer capacitor replaces large leaded film capacitors and is ideal for telecom/modem applications. Using AVX tip & ring capacitor not only saves valuable real estate on the board and reduces the weight of overall product, but also features standard surface mounting capabilities, so critical to new and compact designs. It offers excellent high frequency performance, low ESR and improved temperature performance over film capacitors.
