Through hole resistors are a type of passive electronic component used for various electrical adjustments and applications. They are typically designed for use in printed circuit boards (PCBs). The purpose of a resistor is to control the flow of electricity in an electrical circuit. They are commonly used to limit the amount of current that passes through a circuit, dissipate power, adjust signal levels, divide voltages, and create timing delays. Through hole resistors are indispensable components of electronics which are available in a variety of readings, sizes, shapes, and power ratings.

WW1FT1K21 application field and working principle refers to a series of through-hole resistors designed for use in areas where accurate, low-temperature, and time-dependent coil-carrying resistance is needed. Such application fields include automotive, telecommunication, and industrial automation. These resistors are particularly suitable for applications that require a resistance value that is stable over a wide temperature range, and with a low voltage coefficient. The working principle of the WW1FT1K21 through-hole resistors is based on a Wheatstone bridge design.

The integration of a Wheatstone bridge on the resistor chip ensures that any variation in the current or voltage in the bridge circuit will result in a variation in the resistance value. This is due to the inverse relationship between the resistance and the voltage output from the bridge circuit. By providing an accurate reference voltage, the resistors are able to detect and adjust to changes in the voltage and current flow in an electrical circuit.

The resistors are constructed using a high-grade nichrome film that is wrapped several times around a ceramic core. This core is then connected to a metal base and terminals, and the entire assembly is dipped into a heat-conductive insulating material such as epoxy resin. The result is a resistor with an extremely high thermal coefficient of resistance (TCR) and a low voltage coefficient. This enables the resistor to maintain an accurate value over a wide range of temperatures and voltages, resulting in exceptional accuracy.

The WW1FT1K21 through-hole resistors also offer excellent reliability and repeatability. The stability of the device is verified by measuring the voltage coefficients in two directions. This ensures that the device will operate with a stable, predictable, and accurate resistance value over time. With the implementation of appropriate safety measures, the device can provide reliable and dependable performance.

Thus, the WW1FT1K21 application field and working principle of through-hole resistors make these devices an ideal solution for a number of demanding applications. The resistors are suitable for various automotive, industrial, and telecommunication applications that require a highly temperature-stable and reliable resistor. As they offer a low temperature coefficient of resistance and a high level of accuracy, they are a great choice for any electronic designs.
