Polyester Film Capacitors

This capacitor uses thin polyester film as the dielectric.
They are not high tolerance, but they are cheap and handy. Their tolerance is about ±5% to ±10%.

From the left in the photograph
Capacitance: 0.001 µF (printed with 001K)
[the width 5 mm, the height 10 mm, the thickness 2 mm]
Capacitance: 0.1 µF (printed with 104K)
[the width 10 mm, the height 11 mm, the thickness 5mm]
Capacitance: 0.22 µF (printed with .22K)
[the width 13 mm, the height 18 mm, the thickness 7mm]

Care must be taken, because different manufacturers use different methods to denote the capacitance values.Here are some other polyester film capacitors.

Starting from the left

Capacitance: 0.0047 µF (printed with 472K)
[the width 4mm, the height 6mm, the thickness 2mm]
Capacitance: 0.0068 µF (printed with 682K)
[the width 4mm, the height 6mm, the thickness 2mm]
Capacitance: 0.47 µF (printed with 474K)
[the width 11mm, the height 14mm, the thickness 7mm]

These capacitors have no polarity.
