Motor Run Capacitors Maximise Motor Efficiency


Components Bureau offers new metallised film capacitors designed for AC motor run applications. Available in 25 case and termination styles, they will allow designers to maximise motor life by matching the capacitor value with the motor’s characteristics. This avoids noisy or irregular rotation, and over-heating, says the company.

Capacitance range for the new compact JFS series capacitors is 0.5µF to 100µF. Designers can choose three package formats — the JFS-B~D and JFS-5~9 models have plastic rectangular cases with either wire or solder lug terminations; the JFS-10~21 models have cylindrical plastic cases with wire, solder lug or tab connections and the JFS-22~26, isolated metal cylindrical cases with tabs for use with crimp terminals.

Metal case models offer the withstand voltage of 2,200V between case and terminals. J (±5%) and K (±10%) tolerances can be selected for the plastic case capacitors and J (±5%) for the metal case models.

Rated voltages can be either 250Vac, 370Vac or 450Vac. Low dissipation factors minimise temperature rise and high insulation resistance offers low leakage currents.

The series is UL / cUL certified, and capable of withstanding surges of twice the rated voltage for two seconds. Operating temperature is specified as -40°C to +85°C.

The capacitors are offered for a favorable price and available now, with low minimum order quantities and samples upon request.
