1812PC224KAT1A Description

Short technical summary and product information.

The Kyocera AVX 1812PC224KAT1A is a 0.22µF multilayer ceramic capacitor (MLCC) rated for 250V DC with ±10% tolerance and X7R temperature coefficient. It is part of the Tip & Ring capacitor series, specifically designed for telecom ring detector circuits to block -48V DC telephone line voltage while passing subscriber AC signals (16-25Hz, 70-90Vrms).

 

This capacitor features a surface mount 1812 (4532 Metric) package with plated nickel and tin terminations, making it RoHS compliant. It operates over a temperature range of -55°C to 125°C and offers excellent high frequency performance, low ESR, and improved temperature stability compared to traditional film capacitors.

 

Ideal for replacing larger leaded film capacitors in telecom and modem applications, the 1812PC224KAT1A saves board space and reduces weight while enabling standard surface mount assembly processes.
