Through Hole Resistors

A through hole resistor is a type of resistor that is used in both discrete and surface-mount applications. It is constructed using a spiral wound metal film or a strain-gauge type of resistor and is capable of dissipating relatively high amounts of power. The main purpose of a through hole resistor is to offer a physical control of electric current or voltage, usually through adjustment of the resistance value.

SQM300JB-0R22

SQM300JB-0R22 is a through hole resistor also known as a spiral wirewound resistor or a current sensing resistor. It is a three-terminal resistor which has a connection in the center hole, and two connections between the inner sleeve and the outer sleeve. These are connected via a hole in the center of the resistor, which serves as the connection between the two external terminals. The resistor is non-inductive and has no temperature coefficient, and is sensitive to changes in temperature, making them suitable for many applications, such as voltage regulation and current sensing.

Application Field and Working Principle

The SQM300JB-0R22 is a high performance through hole resistor which can be used for various applications, from current sensing to voltage regulation to precision signal conditioning. It is commonly used in consumer, automotive, and aerospace electronic systems for a variety of applications. The SQM300JB-0R22 is highly reliable, offering a long-term stability and excellent temperature performance. Additionally, it is cost effective and requires minimal maintenance.

The working principle of the SQM300JB-0R22 through hole resistor is quite simple. It consists of a spiral wound metal film or a strain-gauge type of resistor that is wrapped around an inner and outer sleeve. The resistance of the resistor is controlled by the current running through the resistor. This resistance is further divided into two parts, the static resistance and the dynamic resistance. The static resistance is the resistance of the resistor at a given voltage and current level, while the dynamic resistance is the resistance of the resistor at a given voltage and current. The higher the voltage and current, the higher the resistance will be. Furthermore, the static and dynamic resistances can be tuned by altering the current running through the resistor or by adjusting the voltage.

The SQM300JB-0R22 provides an easy and efficient way to control the current and voltage in various devices. The high performance and cost effectiveness make the SQM300JB-0R22 a desirable choice for many applications.
