JFS metallised film motor run capacitor series offered in 25 case and termination styles

Components Bureau introduces the JFS series of metallised film capacitors from jb Capacitors, in 25 case and termination styles, providing excellent performance for AC motor run applications.

The JFS series is available with a very large number of capacitance values, ranging from 0.5µF to 100µF, allowing designers to maximise motor life by matching the capacitor value with the motor’s
characteristics. This avoids uneven motor magnetic fields, which can cause noisy or irregular
rotation, and over-heating.
The compact capacitor series is offered in 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. The withstand voltage for the metal
case models is 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.
Users have a choice of either 250Vac, 370Vac or 450Vac rated voltages and all JFS series models
feature low dissipation factors to minimise temperature rise and high insulation resistance for low
leakage currents. The series is capable of withstanding surges of twice the rated voltage for two
seconds, and will operate over a wide -40°C to +85°C temperature range. The JFS-10~21 models
have received UL / cUL certification.
The competitively priced JFS capacitors are available now, with low minimum order quantities and
samples upon request.
