Through-hole resistors are one of the most common components in electronics today. They are also called axial lead resistors and are found in many consumer products, such as radios, television, and computers. Through-hole resistors are made from a ceramic or a metal alloy, then coated with a resistive material, usually tin or a graphite mix. They are designed to provide electrical resistance, or impedance, against the flow of electrical current. WHB25RFET is a type of through hole resistor that is widely used in the electronics industry.

The WHB25RFET is a 25W through-hole resistor, which means it can dissipate 25 Watts of power. It has a power rating of 12 Watts and a resistance range of 0.1 Ω to 100 KΩ. The resistor is made from a ceramic body with a tin oval plating. The resistor is sealed in a protective coating that prevents corrosion and increases the life of the resistor. The resistor has a low-temperature coefficient of resistance, which means it can maintain its resistance value even when exposed to temperatures as low as -40°C. Additionally, the WHB25RFET is RoHS compliant, meaning it does not contain any hazardous materials.

The working principle of a WHB25RFET through-hole resistor is relatively simple. The resistor is connected to an electrical circuit and acts as a conductor that limits the flow of current. As current flows through the resistor, a voltage drop is produced. This voltage drop is determined by the resistance of the resistor, with higher resistance producing greater voltage drops. This voltage drop can be used to control the flow of current in a circuit, either by reducing the circuit’s current or by limiting it to a certain value. Additionally, the resistor can be used to create a voltage divider, which is a circuit that divides a voltage into multiple voltage sections.

WHB25RFET through-hole resistors are used in a wide variety of applications, including industrial automation, consumer electronics, and automotive systems. For instance, they can be used for power regulating in industrial automation systems, current limiting in consumer electronics, and voltage dividers in automotive systems. In general, through-hole resistors offer greater accuracy, reliability, and cost-effectiveness compared to other types of resistors.

WHB25RFET through-hole resistors are a reliable and cost-effective way to regulate current and reduce the risk of thermal and electrical problems. They are typically used in circuits that require a large amount of current, such as industrial automation, consumer electronics, and automotive systems. The resistor’s high power rating and low temperature coefficient of resistance make it an ideal choice for these applications. Additionally, the resistor is sealed in a protective coating to prevent corrosion and increase its lifespan.
