MK405J40RL: 4μF Balanced Choice

User Pain Points

Some fan applications have capacitance requirements between 3μF and 5μF—3μF is too small for sufficient starting torque, while 5μF may cause overcompensation. This requires a medium capacitance product to meet this portion of needs while maintaining good cost performance.

Product Solution

MK405J40RL provides 4.0μF medium capacitance, 400V rated voltage, and J-class accuracy. This capacitance point finds a balance between small-medium and medium fans, providing sufficient starting torque without causing overcompensation. The metallized polypropylene film structure ensures stable electrical performance.

Selling Points and Value

4.0μF capacitance is a clever balance point, especially suitable for applications where 3μF is insufficient and 5μF is too large. MK405J40RL provides excellent cost performance at this specification, with moderate capacitance, stable performance, and reasonable price. Its strong versatility makes it suitable for various fan specifications.

Application Scenarios

Suitable for medium industrial fans, ceiling fans, duct fans, air conditioner outdoor units, high-power purification equipment, and other scenarios requiring medium capacitance. It is an ideal choice covering small-medium to medium fans, with a wide range of applications.
