Through Hole Resistors are components used in a wide range of applications to limit current, maintain voltage levels in a circuit and provide feedback in control operations. The WW12FT169R is one such resistor made by the company Bourns which is widely used in a variety of applications due to its versatility and outstanding performance. This article will discuss the application field and working principle of the WW12FT169R.

The WW12FT169R is a through-hole resistor with an operating power rating of 0.125W, a power dissipation of 0.2W and a rated voltage of 200V. It is made using a film-based resistor technology and provides excellent long term stability and mechanical robustness. The WW12FT169R has a wide resistance range of 0.1-5Megohm and a tolerance of ±2 to ±10%. It operates over a wide temperature range of -55℃ to +155℃ and has a maximum pulse width of 6ms. The component is also flame retardant and hermitically sealed, making it ideal for harsh environments.

Due to its versatility, the WW12FT169R is suitable for a wide range of applications. It is commonly used in automotive applications such as throttle position sensors and fuel injectors, as well as industrial appliances and medical equipment. It is also used in industrial controls, RF amplifiers, motor controls, LED lighting, home audio equipment, RF optimizers, power supply controls and more.

The WW12FT169R is a standard, non-inductive resistor and its working principle is based on the use of a metal film resistor. The resistor is comprised of a long, thin strip of conductive metal, usually nickel-chromium, that is wrapped in a spiral around an insulating body. The metal film is etched with a patterned groove, which increases the resistance of the component due to the frictional effect as electricity flows through it. The width and depth of the groove determines the value of the resistor, and the entire component is then coated in a protective material, usually plastic, to protect it against environmental damage.

In summary, the WW12FT169R is a versatile and reliable through-hole resistor manufactured by Bourns, and is suitable for a wide range of applications. It has an operating rating of 0.125W, a power dissipation of 0.2W and a rated voltage of 200V. It a long term stability, wide temperature range and hermetically sealed package make it highly reliable in harsh environments. Its working principle is based on the use of a metal film resistor, where an etched patterned groove in the metal increases the component\'s resistance.
