Axial metallised polyester and polypropylene film capacitors

Components Bureau has introduced the JFG series of axial lead, metallised polyester and polypropylene film capacitors from jb Capacitors to the UK market. The compact capacitors are said to feature high-temperature resistance, large capacity and good self-healing properties, they are suitable for use in instrument applications and DC and AC circuits of household equipment, as well as the fractional frequency circuit of acoustic systems.

Constructed from metallised polyester film as medium and electrode the JFGA series is cycloidal in shape and the JFGB series is flat oval – both are rated for input voltages of 100, 250, 400 and 630Vdc. The JFGA series is available in industry standard capacitance values ranging from 33000pF to 68µF, with a standard ±10% tolerance.For the JFGB series, capacitance values range from 10000pF to 68µF, with a standard tolerance of ±10%. Both sub-series feature a withstand voltage classified at 1.6UR for 2s, 1.5UR for 5s and operate over a -40 to 105°C temperature range.

The JFGC and JFGD series cover input voltages of 250, 400, 630, 1000 and 1250Vdc. The JFGC series is available from 47000pF to 56µF with ±10% tolerance, the JFGD series ranges from 22000pF to 47µF (±10%). Both sub-series feature a withstand voltage classified at 1.7UR for 2s, 1.5UR for 5s and will operating temperatures of -55 to 100°C.
