Through hole resistors, such as the HVR3700002103FR500, are essential electronic components used to produce electrical resistance. They act as a limiting agent to control the current flow between electronic components in circuits. Because of their critical role, it is essential to understand the application fields and working principle of through hole resistors.

Application Fields

Through hole resistors are typically used in a variety of applications such as:

• Temperature Sensor Circuits - through hole resistors are often used in temperature sensing circuits to counteract the thermistor’s negative temperature coefficient (NTC). The HVR3700002103FR500 is particularly suited for this application due to its higher resistance compared to other through hole resistors.
• Power Supplies - through hole resistors are also used in power supplies to regulate the current. This helps to ensure that the voltage remains stable and avoid issues with overloading the power supply.
• Automotive Circuits - through hole resistors are frequently used in automotive circuits to adjust the voltage levels and current amplitudes, allowing for the correct functioning of components such as ECUs and sensors.
• Discrete Electronic Components – through hole resistors are also commonly used with simple components such as transistors, switches, and LEDs for the purpose of limiting the current. This helps to prevent damage to the components and ensures that the circuit operates as intended.
• Logic Circuits – through hole resistors are used in logic and digital circuits for the purpose of tiering voltages, or creating an evenly spaced voltage distribution.

Working Principle

Through hole resistors are constructed from a material which has electrical resistance when a current passes through it. This material is typically carbon-film, metal-film or wire-wound alloy. The HVR3700002103FR500 is a metal-film through hole resistor.

The working principle of through hole resistors is based on the concept of electric potential. This concept is based on the idea that a voltage potential exists between two points in a circuit, and that the current (or flow of electrons) will always strive to move from a higher voltage to a lower voltage. This creates resistance as the current must pass through the material, and consequently will give rise to a voltage drop. The degree of voltage drop is directly related to the resistance of the material.

Therefore, the working principle of through hole resistors is based on the ability of the material to resist the current flow, and consequently produce a voltage drop. This voltage drop is then used to limit the current flow and protect the circuit from overloads.

Conclusion

The HVR3700002103FR500 is a through hole resistor which has a range of applications, including temperature sensing, power supplies, automotive circuits, discrete electronic components and logic circuits. The working principle of through hole resistors takes advantage of the electrical resistance of the material used in the resistor, and produces a voltage drop for the purpose of limiting the current flow.
