Through hole resistors are electronic components used extensively in the electronic industry. They are basic types of resistor that are placed in wiring and connection circuits that allow for the electrical current to pass through it. The 91J30RE application field and working principle will be discussed in this article.

First of all, 91J30RE is type of through hole resistors. It is suitable for a variety of applications in different fields from aircrafts, ships, consumer electronics to medical devices and automotive industries. The resistor has wide-range temperature coefficient of resistance (TCR). Its total resistance range is from 0.1 Ohm to 10M Ohm and temperature coefficient of resistance range is from ±100ppm/°C to ±5,000ppm/°C. The manufacturing process of these types of resistors is mainly designed to provide more consistent and reliable performance with tighter tolerances and repeatability.

The working principle of 91J30RE through hole resistors is heat-sensing, which means the resistance varies with temperature. The resistor consists of two resistors in series: the sensing and the feedback resistor. The sensing resistor has a precisely calibrated resistance that increases when there is an increase in the temperature of the resistor. This increment in resistance triggers the feedback resistor which then compensates the resistance of the sensing resistor and thus providing a relatively stable output.

When the temperature of the environment in which the 91J30RE resistor operates exceeds the set point, the heat sensing resistor increases the resistance which is sensed by the feedback resistor. This triggers the feedback resistor to increase its own resistance and thus gives a relatively stable output. When the environment cools down, the sensing resistor reduces its own resistance and the feedback resistor reduces its own resistance, thus giving the same output as before.

The 91J30RE through hole resistors offer superior reliability to a wide variety of applications. The resistor also has high temperature stability, excellent accuracy over wide range of temperature, low moisture absorption, and flame-retardant coating makes it safe to use. It has a wide operating temperature range of -55°C to +150°C. This allows the resistors to be used in extreme conditions without any issue.

In summary, 91J30RE is a type of through hole resistors that is suitable for various applications from aircrafts, ships, consumer electronics to medical devices and automotive industries. The working principle of these resistors is heat-sensing, meaning that the resistance varies with temperature. The resistor also has high temperature stability with excellent accuracy over wide range of temperature. All these features make 91J30RE an ideal choice for applications requiring precise and reliable performance.
