CW00118R00JE70HS Datasheet/PDFThrough-hole resistors are a type of resistor, supported by leads that go through the board and are soldered on the other side. CW00118R00JE70HS is a high-powered metal oxide film resistor which is used in applications that require exceptionally low noise and heat dissipation from the circuit. It is a power resistor with a low resistance value.
Application Field
CW00118R00JE70HS is used in AC mains current circuits, in order to limit it to a certain safe value. It is particularly designed for high voltage and high power applications and thus commonly used in power electronics and power supply control systems. Other applications include in-line current limiter, high voltage motor controllers, auxiliary circuits and battery spot-welding in the blue-tooth headset industry.
The electrical properties of the resistor, including high temperature stability, overload capabilities, small size, high insulation resistance to reduce frequency distortion and audible noise outperforms other resistor types available in the market. The device’s excellent thermal and electrical properties makes it suitable for the application field requiring long service life.
Working Principle
The core of the work principle of CW00118R00JE70HS is Ohm\'s law which states that a current that flows through a conductor between two points is directly proportional to the voltage applied across the two points. The resistor creates a voltage drop across its two terminals which in turn controls the current flowing through the circuit. When current flows through a resistor, some part of the energy dissipates as heat.
CW00118R00JE70HS has a higher power rating which effectively lowers the temperature rise of the circuit by absorbing larger amounts of heat from the circuit. This is due to the design of the resistor which uses an oxide film coating that greatly reduces the conductor resistance. This oxide film is so effective that it can dissipate less than 0.2 Ω of resistance.
The resistor also uses a power rating higher than other resistors, making it ideal for reactive circuits and high-power applications. Moreover, the resistor’s low DC resistance between two terminals and high-temperature coefficient make it suitable for use in both AC and DC circuits.
Conclusion
CW00118R00JE70HS is a type of through-hole resistor used in applications that require low noise and heat dissipation. It has a higher power rating and uses an oxide film that enables it to disperse heat more efficiently and reduce the temperature of the circuit. Ideal applications range from AC mains current circuits, in-line current limiter, high voltage motor controllers, auxiliary circuits and battery spot welding in the bluetooth headset industry.
