Product Overview

RDER73A473K4M1H03A is a high-voltage general-purpose multilayer ceramic capacitor (MLCC) from Murata’s RDE series, featuring a nominal capacitance of 47000pF (47nF), rated voltage of 1000V DC, and X7R dielectric characteristic. With inside crimp taping (M1) and through-hole mounting, it suits high-voltage general electronic scenarios. Measuring 7.5mm × 5.5mm × 4.0mm, 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 equipment, power systems, precision test instruments, and other fields, serving as a stable and reliable energy storage and filtering core component in high-voltage scenarios.
