Through Hole Resistors

CPCC02R7500JE66 is a through hole resistor that is especially used in high-power electronic circuits, typically in the power supply circuit, and its wide application field and working principle are worthy of study.

Application Field

CPCC02R7500JE66 can commonly be used in high-end devices, like medical imaging machines, large industrial welding machines, and so on. It is most commonly used in the high-power rectification, power supply, and buck-boost transformer circuits.

CPCC02R7500JE66 also has good protection performance and several advantages. It has excellent thermal shock resistance, so it can avoid thermal shock under extreme temperature condition. With its high-power harness resistance, CPCC02R7500JE66 can prevent over-current and over-voltage, as well as effectively reducing output noise and reducing signal distortion.

Working Principle

CPCC02R7500JE66 works by three principles, namely voltage division, current absorption and thermal nonlinearity. Voltage division means that CPCC02R7500JE66 divides the dc voltage input into two parts, one is going through the outer contacts and the other one is flowing through the inner contacts, so that the voltage input is restricted to a certain value.

Current absorption refers to the phenomenon of CPCC02R7500JE66 reducing the surge current by absorbing the energy of it. During this process, the temperature of the component increases due to Joule heating, and the negative temperature coefficient of the material further reduces the current.

Finally, the thermal nonlinearity of CPCC02R7500JE66 refers to the phenomenon of changing its resistance value with the changing of the inner temperature, which will also be affecting the output voltage. This feature is very useful for over-voltage and over-current protection, because the resistor can react quickly to the current increasing and further reducing the current until the current is back to a normal range.

In conclusion, CPCC02R7500JE66 is a high power through hole resistor with very wide application field, working principles with good protection performance. Its advantages of thermal shock resistance, high-power harness resistance make it a great fit for various electronic devices.
