Introduction to Through-Hole Resistors

Through-hole resistors are electrical components commonly used in circuit boards that serve to reduce current flow. By adding some form of resistance to a flow of electrons, they can protect sensitive components and also ensure the accuracy of measurements of amplified signals. Through-hole resistors are commonly used in a number of products ranging from consumer electronics, automotive components, and medical equipment.

Types of Through-Hole Resistors

Through-hole resistors come in a variety of types:

• Carbon Composition Resistors – Made from carbon and other materials, these resistors are typically used in high-current applications and are more expensive than other types of resistors.
• Metal Film Resistors – Very small, accurate resistors typically used in high-precision applications.
• Wire Wound Resistors – Usually constructed with a metal core (like a resistor coil), these are very good at dissipating large amounts of energy and can have very low inductance.
• Ceramic Encased Resistors – Constructed like a hollowed-out resistor, these are mostly used in low-power applications.
• Thick Film Resistors – Exactly as the name implies, these are thick-film resistors composed of a film of resistive material encased in a ceramic housing.
• Fusible Resistors – These are specifically designed to break when a predetermined amount of power is exceeded.
• Surface Mount Resistors – These are the most common type of resistors used in electronic devices today and are mounted directly onto the surface of printed circuit boards.

The CP0007820R0JE663 Through-Hole Resistor

The CP0007820R0JE663 is a common through-hole resistor with a power rating of 20 watts and an operating voltage of 600 volts. This high-power resistor is used in a variety of applications such as noise suppression, over-voltage protection, and current limiting. It is commonly used in the automotive, medical, and consumer electronics industries.

The Working Principle of the CP0007820R0JE663

At its core, the CP0007820R0JE663 works on the same principle as all resistors. When electricity flows through a resistor, it encounters a built-in resistance that reduces the current flow. The more resistance a resistor has, the less current will flow through it. As electricity flows through the CP0007820R0JE663, the current is limited to a maximum of 600 volts.

Because of its high power rating and low resistance, the CP0007820R0JE663 is often used to provide electrical protection from surges of unwanted current. In circuits where high current is expected, such as automotive and medical equipment, the CP0007820R0JE663 may be used to limit the current and protect sensitive components.

Conclusion

Through-hole resistors are important components of many electrical circuits and can be used for a variety of purposes. The CP0007820R0JE663 is a high-power resistor that is commonly used in the automotive, medical, and consumer electronics industries for over-current protection and signal precision. By using this resistor, these industries can protect sensitive components and ensure accurate results in applications ranging from consumer electronics to medical equipment.
