Through Hole Resistors

Resistors are an essential component in virtually every electronic circuit. In terms of electronics, a resistor is a passive two-terminal electrical component, that resists electric current and power, limiting the amount of current in the circuit. Through-hole resistors are the most commonly used type of resistor in electronics. They are easy to install and reliable to use.

WNB15RFE Application Field

WNB15RFE through-hole resistors have a variety of applications in consumer, automotive, medical, industrial, military, and other sectors. They are designed to provide a high-performance current sensing solution for the industrial and automotive markets. They offer an extremely wide operational temperature range, robust construction, very low thermal impedance, and excellent electrical characteristics. WNB15RFE is suitable for a wide range of harsh environments, for example, high-humidity, corrosive atmospheres, or extreme temperatures.

WNB15RFE Working Principle

The WNB15RFE resistor is built with a ceramic body and carbon material resistor element. The resistor element is a metal glaze carbon film resistor that is etched onto the ceramic body. The resistor element is then wired to a pair of contact pins that provide the electrical connection between the circuit and the resistor.The resistive ceramic material is made by combining different types of metal oxides, shaping them into pellets, and then firing them in a kiln. This form of resistance is highly stable and provides a very low thermal coefficient of resistance, meaning that it is less affected by changes in temperature. It also allows for very low level resistances, which makes it ideal for current sensing applications.The contacts are typically made from a gold or silver alloy, and they are brazed or soldered onto the resistor body. This provides a good electrical connection with low resistance and minimal contact sliding. The contacts also prevent oxidation of the resistor element, which helps ensure its stability and reliability.The WNB15RFE is an excellent choice for current sensing applications as it provides high accuracy, stability, low noise, and fast response time. It has excellent environmental properties, with sealed contacts, and contact sliding minimized or eliminated. It is also very easy to install and use.
