A through hole resistor, also known as a through-the-board resistor, is a type of resistive element that is designed primarily for mounting through a printed circuit board (PCB). The term "through-hole" actually describes the design of the resistor, which has two legs that are inserted into corresponding holes in the PCB and then soldered in place for a secure and reliable electrical connection. It is a fairly simple component, consisting of a resistive element and two leads for external connections. Its most common applications are in power supply circuits, where it may be used to limit current and/or voltage.

91J33R is a through hole resistors with an operating temperature range of -40°C to 125°C, and a rated power of 0.25W. Its size is compact (0.5w x 0.5h x 0.2l) and it features epoxy coating for enhanced durability, making it suitable for electronic applications indoors or outdoors. The epoxy coating also helps in preventing the resistor from oxidizing, even in humid and extreme temperature environments. The 91J33R is a reliable component for protecting circuits from high voltage and current.

The 91J33R working principle is simple: the resistive element inside the 91J33R produces precise electrical resistance, which acts like a one-way “valve” that limits current flow and voltage in a circuit. This prevents the circuit from overload, overvoltage, and other issues caused by current or voltage overload. By controlling the flow of current and voltage in a circuit, the 91J33R helps to protect the circuit and any other components that are connected to it.

There are numerous applications for the 91J33R through hole resistor, including power supplies, motor control circuits, switching circuits, and relay protection. It is often used in combination with other resistors in applications where variable resistor values are required. It is also suitable for use in a variety of automotive, military, and aerospace applications. Its compact size, good thermal conductivity, and high voltage rating makes it a reliable component that is suitable for a wide range of different electronic applications.

In conclusion, the 91J33R through hole resistor is a reliable and versatile component with a wide range of applications. Its operating temperature range, epoxy coating, and size make it well-suited for various industrial, automotive, military, and aerospace applications. It is capable of providing precise, stable resistances, which helps protect the circuit and any components connected to it from overvoltage and current.
