Through Hole Resistors

Through hole resistors are a type of resistor with metal leads that are inserted into a board as opposed to being soldered onto it. They are often used when a resistor needs to be protected from current or voltage transients, or when a long lived durable resistor is required, and are usually of general purpose resistors that go into the vast majority of electronica circuits.This article will discuss the 93J27R application field and working principle, and how it fits into the broader categories of through hole resistors.

93J27R Application Field

The 93J27R has a wide variety of applications in the field of through hole resistors. Some of the most common applications include:- Motor protection: using the 93J27R in conjunction with motor controllers can provide protection for motors against transients and over-temperature conditions.- Lighting systems: the 93J27R can be used to provide varying light levels when used in conjunction with potentiometers.- Surge protection: the 93J27R can be used to protect against surges in power supply lines.- RF protection: the 93J27R can be used to protect against unwanted RF signals.- Timers : the 93J27R can be used to regulate the time for various types of timer applications.

Working Principle

The 93J27R is a through hole resistor with an ability to handle high-frequency signals that is due to its thick metal film construction. Its most common application is to provide a resistor with low inductance and low capacitance to improve signal integrity. The resistor functions through the creation of an electric circuit through which current is forced to travel, meeting resistance along the way and dissipating it as heat.The construction of the 93J27R includes a non-magnetic stainless steel pipe containing a thick metal film. At the ends of the resistor there are two metal terminals, usually copper, which provide a surface to which the connections can be made. The metal film also provides a low thermal coefficient of resistance, making it suitable for applications requiring precise resistance values.

Conclusion

The 93J27R is a versatile through hole resistor with a variety of applications ranging from motor protection to RF protection. In all cases, it has excellent heat dissipation characteristics, low capacitance and low inductance, making it suitable for high-frequency applications. It is capable of handling high transient currents and supports high thermal coefficients of resistance, making it a desirable component for a variety of electrical applications.
