MKT 1820 Vishay Roederstein DC Film Capacitor MKT Radial Potted Type is a DC Film Capacitor produced by Vishay Roederstein company. It is mainly used for blocking, bypassing, filtering, timing, coupling and decoupling circuits, interference suppression in low voltage applications. High temperature operations. Automotive applications.
The MKT 1820 is a radial potted DC film capacitor from Vishay Roederstein. It is intended for blocking, bypassing, filtering, timing, coupling and decoupling circuits, as well as interference suppression in low‑voltage and automotive applications. The capacitor features a polyester film dielectric, metallized electrodes, and a plastic epoxy‑sealed case that meets RoHS and UL‑94 V‑0 flame‑retardant standards.
Key specifications include DC voltage ratings from 63 V to 1000 V, AC voltage ratings from 40 V to 220 V, capacitance values from 1 nF to 15 µF (E12 series), and tolerance options of ±5 % to ±20 %. The device can operate up to 125 °C continuously (150 °C for limited time) and offers a reliability of over 300 000 h operational life. Recommended packaging options, mounting guidelines, and extensive test procedures are detailed in the document.
