The WW1FT442R is a through hole resistor that is specially constructed for high-power applications. It has a low thermal coefficient to ensure power stability and a tight tolerance to help ensure accuracy. It comes in two versions, a “normal” version and a “high” version, each with its own characteristics. The WW1FT442R is often used where high power and precision requirements need to be met for mission-critical applications.

The WW1FT442R through hole resistor has an operating temperature of -45°C to +150°C. It can handle a maximum power of 4.2 watts and is very thermally stable, with a small thermal coefficient of resistance of +-2ppm/°C. The tolerance of the resistor is also very tight, with a percent variation of +-0.05%. The resistor is moisture resistant, making it suitable for outdoor applications.

The WW1FT442R is an excellent choice for applications that require stability and precision. Due to its small size and thermal coefficient, it is often used for power supply and energy storage devices such as UPS, batteries, and solar cell systems. It is also used in power electronics applications such as motor controllers and converters. In addition, it is ideal for stabilizing waveforms in laboratory testers, medical, and industrial automation applications.

The WW1FT442R through hole resistor works by converting electricity into thermal energy, which is dissipated in the form of heat through its body. The resistor’s body acts as a composition resistive material, with the metal pins providing current flow. The resistance range of the resistor is determined by the combination of material resistivity, length, and cross-sectional area. It is designed to dissipate heat over its entire surface to ensure that no single point becomes too hot.

The WW1FT442R is a robust and reliable resistor that is designed to meet high power and precision requirements in harsh environments and mission-critical applications. It is highly resistant to heat, humidity, and other environmental factors, making it an ideal choice for a wide range of applications. Its small size and low thermal coefficient make it an ideal choice for applications such as power supply and energy storage, power electronics, and waveform stabilization.
