Through Hole Resistors

A resistor is an electronic component used to reduce the flow of electric current, increase or decrease the voltage of the current, or add a constant and known level of resistance into a circuit. Through hole resistors are the most commonly used in the manufacture of printed circuit boards, as the design offers convenience, stability and reliability.

RSF5SSJR-73-12K Application Field and Working Principle

The RSF5SSJR-73-12K is a 5 watt through-hole resistor, made of high temperature epoxy-coated wrap and tin-plated copper wire. It is used mainly for power supplies, air conditioners and other similar applications.

The working principle of RSF5SSJR-73-12K is based on Ohm’s law, which states that the current flow through a resistor is proportional to the voltage applied across it. The resistance value of this resistor is marked on its body and can be changed by varying the length of the copper wire winding or by varying the diameter of the wire.

The addition of a resistor to a circuit keeps the current flow in check, and therefore prevents the part of the circuit it is connected to from becoming overloaded. The current limiting effect of the resistor is especially important when sensitive components, such as transistors and integrated circuits, are used in the circuit.

The RSF5SSJR-73-12K is temperature stable over a wide range. It can operate from -55°C to +155°C. This makes it suitable for a variety of applications, especially those that require temperature stability over long periods.

The RSF5SSJR-73-12K is also resistant to most chemicals, at temperatures up to +250°C. This makes them ideal for use in applications that require resistance to corrosion, such as those found in the automotive industry.

The RSF5SSJR-73-12K is also generally insensitive to vibration, and can be used in applications where high vibration is common, such as when used in aircraft and automotive engines. The use of temperature and vibration resistant resistors can help prolong the life of the circuits they are used in.

The RSF5SSJR-73-12K is also very accurate and reliable. This makes it suitable for use in precision circuits, such as precision oscillators or digital to analog converters. The accuracy of this resistor means that it can be used to maintain the stability of a circuit, even at high temperatures.

In conclusion, the RSF5SSJR-73-12K is a 5 watt through-hole resistor. It is used mainly for power supplies, air conditioners and other similar applications. It is temperature stable, resistant to most chemicals, and insensitive to vibration. It is also very accurate and reliable, and therefore can be used in precision circuitry.
