Iskra KNG1914 50µF 900V DC-Link Film Capacitor

A PCB-mount capacitor from Iskra's KNG1914 high-density DC-link family. The supplied product photos show the markings 50uF/K and 900VDC@85°C. The series uses metallized polypropylene film, with self-healing construction for DC power-electronics applications.

Key product information Capacitance: 50µF. DC voltage marking: 900VDC at 85°C. This is a DC rating, not a 900V AC rating. Tolerance marking: K. Construction: plastic box case with resin-sealed base and four tinned wire terminals for PCB mounting. Series operating temperature range: -40°C to +85°C, subject to the manufacturer's operating and derating conditions.

Application and replacement checks The KNG1914 family is intended for DC-link, DC filtering, frequency-inverter and industrial power-electronics applications. Check the exact electrical rating, ripple-current requirement, operating temperature, lead spacing, body dimensions and terminal arrangement before selecting a replacement. Mechanical dimensions and application-specific performance should be confirmed for the supplied part; do not determine the PCB footprint from a photograph alone. Disconnect power and safely discharge capacitors before handling.

Ordering information Minimum order: 50 pieces. Listed unit prices: US$5.50 for 50-199 pieces, US$5.30 for 200-499 pieces, and US$5.10 for 500 pieces or more. Current stock, lot condition, manufacturing date, delivery and final quotation are subject to confirmation. EW15 is a marking visible in the supplied photographs; no manufacturing date is inferred from it.
