Product Overview

RDER72J474MUB1H03B is a high-voltage general-purpose multilayer ceramic capacitor (MLCC) from Murata’s RDE series, featuring a nominal capacitance of 0.47μF (470,000pF), rated voltage of 630V DC, and X7R (EIA) high dielectric constant characteristic. With straight lead bulk packaging (B1) and through-hole mounting, it suits general high-voltage electronic scenarios. Measuring 7.7mm × 13.0mm × 4.0mm, it operates within -55℃~125℃ with a capacitance tolerance of ±20%, and is RoHS and Halogen-Free (HF) compliant. It has low acoustic noise, supports wave soldering, and is not suitable for implantable devices or automotive infotainment/comfort equipment. Widely used in industrial high-voltage power supplies, power monitoring, test instruments and other high-voltage general scenarios, it serves as a stable and reliable energy storage and filtering component.
