GHM2000/3000 series are monolithic ceramic capacitors produced by Murata Manufacturing Co., Ltd. The series has safety approval, the rated voltage is 250V, and it is suitable for AC and DC circuits.
The GHM2000/3000 series are surface‑mount monolithic ceramic chip capacitors designed for AC line filtering and X/Y applications in switching power supplies, ballasts, telephones, fax machines and modems. They feature Sn‑plated external electrodes for lead‑free soldering, are reflow‑solderable, and meet multiple safety standards (VDE, SEV, SEMKO, BSI, UL).
The datasheet provides full part‑numbering, dimensional data, electrical characteristics, and extensive test procedures, including temperature range, dielectric strength, insulation resistance, dissipation factor, and humidity testing. Approval standards and recognized safety numbers (e.g., UL1414, IEC384‑14) are also listed.
