Through Hole Resistors

Through hole resistors are resistors that are mounted in a circuit board hole and stay permanently on the board. They are typically used in circuits with higher currents or higher voltage than surface mount resistors. Through hole devices are typically more expensive than surface mount resistors due to higher manufacturing costs associated with through holes.The WNB250FET is a through hole resistor designed for a large variety of applications. It is a 250 watt power resistor offering a wide range of resistance values from 22Ω to 10KΩ in 2% and 5% tolerances. In addition, the resistor is known for its robust construction, fast delivery, and a variety of different mounting options.

WNB250FET Application Fields

The WNB250FET is used in a variety of applications including motor drives, industrial motors, power electronics, electric vehicles, and renewable energy applications. It is also suitable for power supplies and inverters, HVAC and industrial automation applications, as well as AC/DC lighting control applications. In addition, the resistor can be used for a variety of different power levels up to and exceeding 250W.

WNB250FET Working Principle

The working principle of the WNB250FET is based on the electrical resistance principle. This principle states that electricity will always take the path of least resistance. When voltage is applied, the device will resist the flow of electricity, causing it to dissipate as heat. The more resistance offered by the device, the more heat is generated. By adjusting the resistance to the desired level, the device can be used for a variety of applications and power levels.The WNB250FET is constructed with a copper-plated steel core material for increased power dissipation and reliability. Additionally, the resistor is fitted with a glass-filled polyester which is highly resistant to heat and temperature changes. The resistor also features a reinforced stainless steel construction which increases the strength of the resistor and helps reduce the risk of failure due to vibration or shock. The WNB250FET is also available in surface mount packages for applications that may require it. By using a surface mount version, the user can easily integrate the resistor into the circuit without having to drill any holes or mount any components. This makes it an ideal solution for applications where space is limited or the need to be quickly installed.

Conclusion

The WNB250FET through hole resistor is an excellent solution for applications where higher current or voltage is required or where a more robust construction is necessary. The resistor offers a wide selection of resistance values and combinations, along with a reinforced stainless steel construction and a glass-filled polyester material for heat dissipation. Additionally, the resistor is available in both a through hole and surface mount format for added flexibility and convenience.
