Overview
The TAJA105M025RNJ is a multilayer ceramic capacitor (MLCC) designed for high-reliability decoupling, filtering, and signal conditioning in electronic circuits. It is widely used in industrial automation, IoT devices, and embedded microcontroller power rails, where stable capacitance, low ESR, and precise voltage handling are required.
The device is also available in tape-and-reel packaging as TAJA105M025SNJ for automated assembly. Compared to TAJA105K025RNJ, which has a tighter ±10% tolerance, the M-grade TAJA105M025RNJ (±20% tolerance) provides slightly wider capacitance variation, making it suitable for applications where precision is less critical.
