High voltage capacitors for ionizers and air purifiers
For the low current high voltage circuits of ionizers, air purifiers and car air purifiers.
Ionizers and electrostatic air purifiers draw very little current but need several to over ten kilovolts, normally from a small oscillator and a voltage multiplier. These circuits are size-sensitive: the YL series (100 pF, 8 mm diameter) is small enough for multi-stage multipliers, and B series parts rated 4–10 kV cover lower voltages or larger capacitance.
Typical equipment
- Negative ion generators
- Air purifiers
- Car air purifiers
- Fresh-air system purification modules
- Ionic hair dryers
