BLEEDER RESISTORS DESCRIPTION
Type of Rating | Deduction Curve | Characteristics | Dimensions |
Besides FCBs, we also design thick film high voltage fixed resistors which known as bleeder resistors.
It has the features of:-
1. Compact thin body design is achieved by thick film construction.
2. High reliability and high stability.
3. High voltage capability from 5 KV to 35KV.
4. Applications:
- High voltage resistors are designed and suited for use in high value applications requiring high voltage regulation and/or attenuation such as:
- Copiers
- X-ray Equipment
- Microwave Ovens
- Air-Conditioners
- CRT Circuits
- Power Suppliers
- Voltage Multipliers
- Medical Equipment
5. High voltage dividing resistors are designed for purpose to produce voltage control output of high voltage power supply and custom circuit design available from 1/300 to 1/6000 dividing voltage output suitable for the peripheral circuit schematics.
6. High voltage resistors are designed for use in depending upon the kind of potting materials, semi-flexible epoxy resin overcoat type are provided.
