Through hole resistors are an important type of electrical component that can be used to control the flow of electricity in an electronic system. The WNA200FE is a type of through hole resistor that has been designed for high-power applications. This article will explain the application field and working principle of the WNA200FE.

The WNA200FE is a high-power through hole resistor designed for electrical systems with high current loads. It has a maximum dissipation of 30 Watts, and is capable of withstanding a maximum voltage of 1200 V. This makes it ideal for high-power applications such as in inverters, uninterruptible power supplies (UPS), and other high-power systems. The resistor has a typical thermal resistance of 4.6 °C/W, which is low for a device of this type.

The WNA200FE is a non-inductive resistor, which means that it will not create an inductance in the system it is connected to. This is important for high-power systems, as inductors can cause interference and instability. The device is also designed to have a low-impedance, to prevent any additional series resistance from building up in the circuit.

The WNA200FE is also designed to have a high rise and fall time response. This means that it can quickly respond to changes in current, and adjust accordingly. This is vital in high-power systems, as current changes can cause instability and loss of power. The resistor is also designed to have a high resistance stability over a wide temperature range.

The WNA200FE is a box type resistor, and its construction features two layers of metal film plus black shell body material. The metal film provides conductivity, while the black body material helps to dissipate the heat. The resistor is also designed to be vibration resistant and shockproof, to ensure reliable performance even in harsh environments.

The working principle of the WNA200FE is relatively simple. When a current passes through the resistor, the resistor will resist the current, reducing the overall voltage in the system. The amount of resistance is determined by the amount of metal film in the resistor. The more metal film, the higher the resistance. The metal film also determines the stability of the resistor, as it will remain constant over different temperatures.

In conclusion, the WNA200FE is a high-power through hole resistor designed for high-power electrical system applications. It has a high maximum dissipation of 30 Watts and a low thermal resistance, and is non-inductive to prevent system interference. It also has a high rise and fall time response, to quickly respond to current changes, and is vibration and shockproof. The working principle of the resistor is relatively simple, resisting a current and reducing the voltage, while the amount of resistance is determined by the amount of metal film in the resistor.
