MK505J40RL: 5μF Large Capacitance Start Capacitor

User Pain Points

Medium to large motors typically require larger start capacitors to provide sufficient phase shift, but large capacitance capacitors are often large in size and expensive. Additionally, large capacitance capacitors have poor high-frequency characteristics and may not meet requirements in some applications with strict power factor demands.

Product Solution

SK MK505J40RL film capacitor provides 5.0μF large capacitance, 400V rated voltage, and J-class accuracy meeting general industrial application requirements. The metallized polypropylene film structure ensures low loss and high-frequency performance, with self-healing function improving product reliability. The compact package design controls size while ensuring capacitance.

Selling Points and Value

The large capacitance design of MK505J40RL reduces parallel connection requirements and simplifies circuit design. As a start capacitor, it can provide strong starting torque for medium to large fans, shorten startup time, and reduce motor temperature rise. Its excellent frequency characteristics maintain low loss in operating state, improving motor operating efficiency.

Application Scenarios

Widely used in medium industrial fans, HVAC system fans, pump motors, air conditioner compressor matching, and other equipment requiring large start capacitors. Especially suitable for start and run compensation of single-phase asynchronous motors, it is a preferred solution for industrial fan systems.
