Product Overview

RDER73A472K2M1H03A is a high-voltage general-purpose multilayer ceramic capacitor (MLCC) from Murata’s RDE series, featuring a nominal capacitance of 4700pF (4.7nF), rated voltage of 1000V DC, and X7R dielectric characteristic. With inside crimp taping (M1) and through-hole mounting, it suits high-voltage circuit applications. Measuring 5.5mm × 4.0mm × 3.15mm, it operates within -55℃~125℃ with a capacitance tolerance of ±10%, and is RoHS and Halogen-Free compliant. This lead-free and halogen-free capacitor is widely used in industrial high-voltage power supplies, communication base stations, test instruments, and other fields, serving as a stable and reliable energy storage and filtering component in high-voltage scenarios.
