Featurss:1. Adopt accurate polypropylene film as medium, aluminium foil make electrode coil together.2. There are not oxygen and copper that draw the line, reduce the lead wire to
loss3. The stability of capacity of static, capacity are high in precision, the fine coefficient of temperature.4. The non-conductor absorbs coefficient small, it is very low to
loss the angle tangentUse1. Shake the circuit accurately.2. High-accuracy total mark circuit3. Timing circuit expected high
