MKP 1840-M is a single unit metallized polypropylene film capacitor produced by Vishay, with an rated voltage of 250V, 400V, 630V, 1000V, an rated capacitance of 1000pF to 6.8μF, a dielectric material of polypropylene, electrodes of metallized, leads of tinned wire and a maximum working temperature of 100°C.
The MKP 1840-M is a metallized polypropylene film capacitor offered in a mini‑version (‑M) with radial, potted construction. It is intended for high‑frequency and pulse operations, such as TV‑set deflection circuits, SMPS, loudspeaker crossover networks, electronic ballast, filter, timing and sample‑and‑hold circuits.
The document lists detailed electrical ratings, mechanical dimensions, packaging options, mounting guidelines, storage conditions and extensive test requirements. It also includes application limits, noting that the part is not suitable for mains‑line use without additional protection.
