Introduction to Through Hole Resistors

A resistor is a two-terminal electrical device that resists the flow of electric current and is used to control voltage, current, and power in circuits. They are essential components in circuits where voltage supply is required (such as amplifiers). Resistors come in various types, sizes, shapes, temperature coefficients, and tolerance ratings, and can be grouped into two main categories: surface mount resistors and through hole resistors.

What is a Through Hole Resistor?

A through hole resistor is a type of resistor that is typically used in circuits where two metal leads are pierced, twisted or soldered to a terminal pad. Through hole resistors provide superior strength for high-temperature soldering due to their physical size and greater heat dissipation capacity than their surface mount counterparts.Through hole resistors, also known as axial resistors, consist of a resistive element wrapped in an insulating sleeve. The leads, also known as "fins," extend from either side of the sleeve. When it is necessary to change the value of a resistor, the element can be replaced.

ER74R12JT Application Field and Working Principle

The ER74R12JT is a through hole resistor which has an axial type and accommodating body, a maximum rated voltage of 1.2KV and maximum rated power of 2W. It is a low-noise, high-quality resistor perfect for use in high frequency circuits such as audio amplifiers, telephone lines, and other electrical applications.The working principle of the ER74R12JT follows the basic working principle of all electrical resistors: the resistor controls the amount of electric current that can flow through the circuit. The voltage drop across the resistor is proportional to the current that is flowing through it.The ER74R12JT is a precision resistor with superior quality thanks to its tight tolerance and 0.005% temperature coefficient of resistance (TCR). This resistor can be used in power supplies, receivers, amplifiers, radar systems, and other critical applications requiring precise control of electrical current.
