Through Hole Resistors

Through-hole resistors, also called leaded resistors, are components that use a physical connection between a resistor and a printed circuit board (PCB). The leads, which extend from the components, are inserted into holes in the PCB before being soldered in place.

RNF12JTD240K is a type of through-hole resistor. This resistor has a power rating of 240K Ω and a power rating of 5%. It is a ceramic resistor, with a temperature coefficient of 1.8 ppm per degree C and a tolerance of 5%. The RNF12JTD240K is most commonly used in high-precision, high-voltage electronic circuits, such as power supplies and control circuits.

RNF12JTD240K Application Field

The RNF12JTD240K is most commonly used in electrical circuits requiring precise resistor values, such as DC to DC converters, voltage regulators, switching power supplies, high-voltage audio amplifiers, etc. It can also be used in transmitting and receiving electronics, automotive and industrial electronics, process control systems, etc. In addition, it is compatible with automotive-grade soldering materials, making it suitable for use in automotive applications.

RNF12JTD240K Working Principle

RNF12JTD240K consists of two ceramic bodies that form a resistor. The resistor is constructed by sintering a ceramic material with a charge current running through it. The material determines the resistance value. The ceramic material has a high resistance value, and when a charge current runs through it, its resistance changes. This change in resistance results in an experienced voltage drop when current passes through the resistor.

The resistor is also designed with a terminals or leads to aid with connections. These terminals or leads are connected to the PCB, allowing current/voltage to flow through them. The resistor operates using Ohm’s law, which states that the voltage (V) across the resistor is directly proportional to the current (I) passing through it, and inversely proportional to the resistance (R). This provides the required resistance value for the system.

Conclusion

RNF12JTD240K is a through-hole resistor used in high-precision and high-voltage electronic circuits. It consists of two ceramic bodies sintered to create a resistor, and its leads are connected to the circuit board for enabling current/voltage to flow. It operates using Ohm’s law and offers a power rating of 240KΩ and tolerance of 5%.
