Capacitor Start 100-125UF is engineered to provide essential starting torque for single-phase induction motors by briefly supplying a substantial electrical boost during motor startup. Featuring a capacitance range of 100–125 microfarads (µF) and typical voltage ratings between 250V and 330V AC (50/60 Hz), it is a non-polarized electrolytic capacitor intended solely for intermittent use—activated for just seconds during startup and then disconnected from the circuit via a relay or centrifugal switch.

The cylindrical design often includes a robust PVC or plastic cover, standard terminal connections (such as spade, Faston, or screw terminals), and may incorporate a mounting bracket for secure installation. This capacitor is built to withstand temperature ranges from -40°C to +65°C, ensuring reliable performance in demanding environments. Its tolerance is typically 0/+20% or ±10%, and it is rated for thousands of start cycles.

Capacitor Start 100-125UF is vital for applications where robust and reliable starting is critical. It is commonly found in pumps, air compressors, HVAC systems, pressure washers, and similar machinery. This capacitor is intended for start-duty only—using it for continuous operation will lead to rapid deterioration.
