Category Overview
A start capacitor is a special type of capacitor that comes into the circuit to provide the high torque that single-phase asynchronous motors need at the moment of initial start-up. Also known as "starting capacitors", these components are used in many appliances such as air conditioners, refrigerators, freezers, washing machines, water pumps and compressors. Unlike run capacitors, start capacitors are designed for a short-duration but high-capacitance duty; once the motor reaches its speed, they are taken out of the circuit by a centrifugal switch or PTC relay. In this category, Yedepa.com offers original-quality products in a wide microfarad (µF) range suitable for industrial and household appliance applications, in the 250 VAC and 330 VAC voltage classes.
Products You Can Find in This Category
So that you can meet your spare part needs from a single point, start capacitor options in different µF values according to motor power and application type are ready in our stock. All models are manufactured to operate at 50/60 Hz frequency and have a capped housing against heat and humidity changes. Our featured product groups in the category are:
- 36-43 µF 330 VAC Start Capacitor with Cap — ideal for small and medium-power compressor motors.
- 43-53 µF 330 VAC Start Capacitor with Cap — value range frequently preferred in refrigerator and freezer compressors.
- 72-88 µF 330 VAC Start Capacitor with Cap — suitable for medium-to-large power air conditioner and pump motors.
- 88-108 µF 250 VAC Start Capacitor with Cap — provides starting support in high-torque household appliance applications.
- 270-324 µF 330 VAC Start Capacitor with Cap — for high-power industrial motors and industrial compressors.
Selection Criteria and Tips
There are three basic parameters to consider when choosing the right start capacitor: capacitance range (µF), operating voltage (VAC) and frequency compatibility (Hz). The safest method is to choose a model that exactly matches the label information on the old, failed capacitor. If the label is unreadable, the appropriate range should be determined according to the power (HP/kW) value on the motor nameplate. When choosing the voltage class, switching to a lower VAC value than the existing one is definitely not recommended; however, a higher voltage class (for example 330 VAC instead of 250 VAC) is considered safe. When making the connection, make sure the capacitor has been discharged, and check the terminal tightness and insulation. Choosing the wrong µF value can cause the motor to overheat, fail to start and burn out the winding; for this reason, it is useful to get support from an experienced technician who takes measurements.
