AVX Tip and Ring, or ring detector, MLCCs are designed as a standard telecom filter to block -48 volts DC telephone line voltage and pass subscriber's AC signal pulse (16 to 25Hz, 70 to 90 VRMS). The ringer capacitors replace large leaded film capacitors and are ideal for telecom/modem applications.
Using AVX's Tip and Ring Capacitors not only saves valuable real estate on the board and reduces the weight of the overall product, but also features standard surface mounting capabilities which is critical to new and compact designs. The AVX Tip and Ring Capacitors are offered in standard EIA sizes and standard values. They offer excellent high frequency performance, low ESR, and improved temperature performance (X7R) over film capacitors.
