Through Hole Resistors are type of resistors that require the use of a drill or drill bit to be mounted into a PCB, otherwise known as Printed Circuit Board. Through Hole Resistors are used to regulate the flow of electrical current in circuits. They are commonly used in components such as transistors, capacitors and diodes and can also be used to limit the current in electrical circuits. Through Hole Resistors are available in a variety of sizes and styles, including axial, annular, square and circular.

A LR1F12R1 is a through-hole resistor developed by Yageo Corporation that is widely used for circuit board protection applications due to its high resistance and low noise characteristics. It is specifically designed to be highly robust against ESD strikes, surge and noise pulses. The LR1F12R1 features 12 Ohm of resistance, which is both the nominal resistance and the maximum operating resistance when tested at 10kHz AC, 300V and 250°C. The operating temperature range of the LR1F12R1 is from -55°C to +125°C, allowing for wide range of circuit protection temperature areas.

The LR1F12R1 operates according to the ohm law, which states that current is equal to the voltage applied to the resistor divided by its resistance. As the voltage increases, the current through the resistor increases at a corresponding rate, which means that the LR1F12R1 may be used to limit the current in electrical circuits. In addition, it can also be wired in series with other resistors to achieve higher resistances or in parallel to achieve lower resistances. The LR1F12R1 is also bidirectional, meaning the current can flow through it in either direction.

The LR1F12R1 is constructed from a sintered carbon material rather than a solid film, which makes it more resistant to air, oxidative, and vibration damage. The resistor is encased in a plastic-like material that has been designed to be mechanically and environmentally protective. According to electrical and mechanical testing, the LR1F12R1 has high resistance and very low earth leakage peak current.

LR1F12R1 is used in applications such as computers, communications devices, industrial robots, aerospace, and military and defence systems. In these applications, it is used to protect the circuit board from the high currents and voltages that may arise due to surges, ESD strikes, and noise pulses. The LR1F12R1 is also suitable for general purpose overvoltage protection and interference suppressions under high temperature operating conditions. As its uses are wide and varied, it is a reliable and popular choice for a wide range of applications.

In conclusion, the LR1F12R1 is a through-hole resistors that is capable of 12 Ohms of resistance, has a wide operating temperature range and is highly robust against ESD Strikes, surge and noise pulses. The LR1F12R1 is designed specifically for circuit protection applications, and is suitable for use in computers, communications devices, industrial robots, aerospace and military and defence systems. It is widely known as a reliable and popular choice for a wide range of applications.
