Through Hole Resistors, specifically RN65C3090FRE6, are electronic components used to limit the flow of electricity in a circuit. They come in many different sizes and forms, making them highly customizable for any electrical project. They are typically used in circuits carrying high current and being required to resist high voltages. RN65C3090FRE6 are designed to deliver reliable and precise performance across a wide temperature range.

Applications

RN65C3090FRE6 can be used in a variety of applications, such as:

• Heating and air conditioning control systems
• Automotive applications, including ignition circuits
• Lighting control circuits
• Power supplies, motor speed control, and AC circuit protection
• High voltage switching equipment

The RN65C3090FRE6 through hole resistor is also common in industrial equipment, including fuel cells, medical devices, and signal processing components that require reliable performance in extended temperature ranges.

Features

• Generous power rating up to 2 watts
• High-pulse surge current ratings
• Wide operating temperature range of -55°C to +125°C
• High surge pulse tolerance
• Non-inductive construction
• Epoxy-coated for excellent insulation and adhesion

The through hole resistor design of the RN65C3090FRE6 eliminates the need for wirewound resistors in many applications. The placement of the resistor leads and construction of the resistive element provide more reliable performance than either wirewound or film based resistors. Its epoxy power coating helps protect the resistor leads and resistive element from environmental conditions and physical damage.

Working Principle

At its core, the working principle of a resistor is simple: electricity flows through a conductive material, and meets resistance along the way. This resistance then translates the electrical energy into heat, which is then dissipated. The classic analogy for understanding this idea is the “water pipeline metaphor.” A pipe carrying water can be blocked partially or fully with material that offers resistance to the water’s journey, causing the water to heat up along the way. In essence, this is how electricity behaves as well, and a resistor can be implemented to provide resistance, causing the flowing electricity to heat up.

The RN65C3090FRE6 through hole resistor utilizes this principle in its construction. Its electrical resistive element, typically comprised of a metal oxide or carbon-filled plastic film, provides the resistance to the current flow. The leads and surrounding epoxy coating insulate the resistor and absorb the heat as the electrical current flows through it. This combination of resistive element and insulation makes it possible to precisely control electrical system performance, allowing engineers to design circuit protection systems with total confidence.
