A leading resistors manufacturing company, Pakheng, can supply Ceramic Tube Wire Wound Power Load Resistors Fixed Type Through Hole 25 Watt 100ohm High Resistance with original of Shenzhen China. We devoted ourselves to resistors research 25 years. Covering most of Europe and America market. We are also can supply film resistors and wire-wound resistors, having our group of professional personnel at your service.
Ceramic Resistors Function
Limiting current: By introducing resistance into a circuit, resistors can limit the amount of current that flows through the circuit. In accordance with Ohm’s law, if the voltage in a circuit remains the same, the current will decrease if you increase the resistance.
Dividing voltage: You can also use resistors to reduce voltage to a level that’s appropriate for specific parts of your circuit. For example, suppose your circuit is powered by a 3 V battery but a part of your circuit needs 1.5 V. You could use two resistors of equal value to split this voltage in half.
Resistor/capacitor networks: Resistors can be used in combination with capacitors for a variety of interesting purposes.
1. High power rating, high overload.
2. Copper wire or chrominum alloy wire is wound on the ceramic tube coated with non-flammable resin, good dissipation, high stability, and long life.
3. Widely used in power supply, transducer, elevator, arena audio and lifting, braking, Ship, load equipment, high requirement equipment Industry, ect.
4. For customer specifications, can be made into variable.
