Through Hole Resistors: 90J250E Application Field and Working Principle

Resistors come in many forms, including discrete or packaged components, and through hole or surface-mount varieties. Through-hole resistors are passive components whose purpose is to reduce voltage by dissipating electric current in a circuit. The 90J250E through-hole resistor is one of the most widely used resistors in consumer electronics. This article will discuss the application fields of the 90J250E as well as its working principle.

The 90J250E is a 97-watt power resistor that can handle high current loads in harsh environments. It is made of a carbon composite material that is both heat and corrosion resistant. It has a low temperature coefficient and low noise. These features make it suitable for use in power supplies, motor drives, solar inverters, and many other industrial and consumer applications. It is also used in automotive electronics, lighting fixtures, and other applications where a reliable, durable resistor is required. The 90J250E has an operating temperature range of -65 to +200 degrees Celsius and is available in a variety of resistances, from 1 to 5 kilohms.

The working principle of a through-hole resistor is fairly simple. When electric current passes through a resistor, the resistance of the wire causes it to heat up. The higher the resistance, the more heat is generated. The heat generated is dissipated into the surrounding environment, thus reducing the voltage in the circuit. The 90J250E is designed to dissipate this heat efficiently by using a metal case that helps to radiate the heat away from the resistor. The metal case also helps to protect the resistor from mechanical damage and provides additional insulation. Finally, the metal case also helps to control the frequency of the voltage in the circuit, as the metal case acts as a filter for any high-frequency noise.

The 90J250E through-hole resistor is an excellent choice for a variety of consumer and industrial applications. Its high current ratings, low temperature coefficient, and low noise make it suitable for use in demanding environments. Additionally, its rugged metal case helps protect the resistor from damage and provides additional insulation and filtering. With its wide range of resistances, the 90J250E is sure to meet the needs of any application.
