Through Hole Resistors (THRs) are commonly used in many industrial, electrical, and communication applications. The WHC100FET is a Through Hole Resistor (THR) that is specially designed to meet the rigorous requirements of industrial and automation applications, including providing direct current (DC) sensing. This THR provides high-temperature and high-voltage resistance, as well as power dissipation capabilities that are far superior to those of conventional resistors.

The WHC100FET is a four-terminal device using a film resistor element, and has terminals that are through-hole. It uses five layers of resistive material that are separated by an insulation barrier that is made of Teflon. This material is chosen because it is a highly-stable, low-noise material that offers resistance to moisture and resistance to corrosion. The resistive material used in the construction of the WHC100FET is a high purity, low temperature material that is resistant to changes in temperature, humidity, and electrical characteristics over the lifetime of the device.

The WHC100FET has an operating temperature range of –55°C to +225°C and is rated for 500V and 2000V operating voltage. Additionally, it has a maximum allowable power dissipation of 2W. The THR also features a low TCR (temperature coefficient of resistance) of approximately 0.5 ppm/°C which means its resistance does not significantly change over time or temperature.

The WHC100FET is specifically designed for sensing applications in industrial and communication equipment. It can be used in various circuits for sensing currents in motors, transistors, and other devices. It is also used as a precision current-sensing resistor or a general sense resistor in power supplies, amplifiers, computers, and other types of electronic equipment. Additionally, it has been used in the protection of safety meters, such as smoke detectors and carbon monoxide detectors.

The WHC100FET is simple to use, as it has two leads for attachment. It can also be installed in tight spaces, as it has an overall size of 15x15mm. The THR has a high working voltage of up to 2000V, and a high thermal loss of 0.09 W/°C. It also has a typical initial accuracy of 1% when it is connected to 2 ohms or less.

In summary, the WHC100FET is an extremely reliable, through-hole resistor that is suitable for a wide variety of industrial, communication, and sensing applications. It offers a high tolerance to temperature, voltage, and current fluctuations and has a long operational lifetime. It is also easy to install and provides excellent power dissipation capabilities. As such, it is ideal for use in motors, transistors, and other high-precision electronic equipment and makes a great addition to the THR range.
