KYOCERA AVX 1812PC474KAT2A SMD Multilayer Ceramic Capacitor, 0.47 µF, 250 V, 1812 [4532 Metric], ± 10%, X7R

1812PC474KAT2A is a Tip & Ring MLC chip capacitor. This Tip & Ring or ring detector multilayer ceramic chip capacitor is designed as a standard telecom filter to block -48Volts DC telephone line voltage and pass subscriber�s AC signal pulse (16 to 25Hz, 70 to 90Vrms). The typical ringing signal is seen on figure on page 132. The ringer capacitors replace large leaded film capacitors and are ideal for telecom/modem applications. Using AVX �Tip & Ring� capacitors not only saves valuable real estate on the board and reduces the weight of overall product, but also feature 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.
