Through hole resistors are widely used in the electronics industry, due to their cost effectiveness, low profile, and wide range of resistance values. The WW1FT249R is an especially popular through hole resistor for many applications. This resistor is designed to be used in DC and AC circuits and is designed to draw very little current compared to other resistors in the same size class. The WW1FT249R resistor is also one of the most reliable resistors on the market, with excellent temperature tolerance and long-term stability.

The WW1FT249R resistor is rated for a maximum power dissipation of 0.25 watts at temperatures up to 70°C. The resistor is also capable of withstanding a surge current of 10A for up to 10ms at a temperature of 25°C. The maximum DC voltage rating of WW1FT249R is 35V. The maximum limit of AC voltage is 25Vrms, depending on the frequency of the applied voltage.

The WW1FT249R resistor is an axial leaded resistor, which is a type of through-hole resistor. This means that the resistor is made up of two metal leads, or terminals, that are connected by a center core. The center core of these resistors is often made of a ceramic material. The ceramic core is what provides the electrical path for the current to pass through the resistor. The two leads, or terminals, are then connected to the desired components in the circuit. This allows the resistor to be directly mounted to a circuit board, providing excellent heat dissipation.

When power is applied to the WW1FT249R resistor, the ceramic core will become heated up due to the voltage being applied to it. This increase in temperature will cause the ceramic core to expand slightly, which will then cause a change in the resistance value of the resistor. This change in resistance is due to the thermistor effect, which is the phenomenon where the resistance of a material changes with an increase in temperature. The WW1FT249R utilizes this effect in order to regulate the current passing through the resistor, allowing for an increase or decrease in current depending on the voltage applied.

There are many uses for the WW1FT249R resistor, such as in power supplies and power electronics, motor drive circuits, current sensing, voltage regulation, and high temperature sensing. It is perfect for applications where accuracy and repeatability are needed, as its thermistor effect allows for accurate and predictable control of the electrical current passing through it. It can also handle high levels of current, making it ideal for applications that require high power dissipation. In summary, the WW1FT249R resistor is an excellent choice for many circuits, due to its versatility, accuracy, and reliability.
