jb Film Capacitors

Keywords : radial lead type, axial lead type, plastic film, paper, polystyrene.

Film Capacitors which use polystyrene, polycarbonate or Teflon as their dielectrics are sometimes called "Plastic capacitors". The construction of plastic film capacitors is similar to that for paper film capacitors but use a plastic film instead of paper. The main advantage of plastic film capacitors compared to impregnated-paper types is that they operate well under conditions of high temperature, have smaller tolerances, a very long service life and high reliability. Examples of film capacitors are the rectangular metallised film and cylindrical film & foil types as shown below.

Radial Lead Type
Axial Lead Type

The film and foil types of capacitors are made from long thin strips of thin metal foil with the dielectric material sandwiched together which are wound into a tight roll and then sealed in paper or metal tubes.  These film types require a much thicker dielectric film to reduce the risk of tears or punctures in the film, and is therefore more suited to lower capacitance values and larger case sizes.

Metallized foil capacitors have the conductive film metallized sprayed directly onto each side of the dielectric which gives the capacitor self-healing properties and can therefore use much thinner dielectric films. This allows for higher capacitance values and smaller case sizes for a given capacitance. Film and foil capacitors are generally used for higher power and more precise applications.

jb Capacitors Company offer Polystyrene film capacitors

key words: Polystyrene film capacitors, Radial Film Capacitors, Axial film capacitors; As you know, Polystyrene capacitors are not widely available these days.there are only a few suppliers of Polystyrene film capacitors in current market, jb capacitors company can offer you this series.

Polystyrene film capacitors provide extremely low losses, low dielectric absorption, good long-term stability, very high insulation resistance and a small negative temperature coefficient. With their excellent electrical characteristics, Polystyrene film capacitors are ideal for use: tuner & equalization circuits; commercial, industrial & measuring instruments; critical analog circuits; filters, tuned, integrators & sample-and-hold circuits; IF transformers; pulse networks; analogue & digital computing circuits and critical timing circuits such as VCO (voltage-controlled oscillators) and VCF (voltage-controlled filters).

Our JFR-Polystyrene Film Capacitor, including axial and radial type, is with high precision of capacitance.

jb one part of test motor run capacitors

Keywords: motor run capacitors; motor starting capacitors

You can test a motor run capacitor using a 100 watt light bulb and a digital ac volt meter.
Never use an ohm meter to test a motor run capacitor. It is a very inconclusive test and only shows that there is "something" in the circuit. You are essentially "shooting blind".
To test motor start capacitors you will need a 200-300 watt bulb depending on the size.
Caution: capacitors can hold a charge when removed from the circuit unless they have a bleeder resistor. Discharge the capacitor through the light bulb before handling. A capacitor in a working motor circuit cannot hold a charge, it is discharged the instant the power is removed.

Pls. see our JFS--Motor starting capacitors, here is datasheet: http://www.jbcapacitors.com/pdf/JFS-Motor-Starting-Capacitor.pdf. you will find the quality is quite good when you use the correct test mothod.
