Through Hole Resistors

Through hole resistors come in various shapes and sizes, but they all have one common purpose: to limit current in a circuit. The RNMF14FTD1K82 is one type of through hole resistor. This article will explain its application field, and the working principle of this device.

Introduction to RNMF14FTD1K82

The RNMF14FTD1K82 is a through hole resistor with an extended resistance range from 0.1 ohms to 1M ohms. This device is short, compact, and highly reliable, and offers users an extended range of resistance values that can be built into equipment for consistent current limiting protection.The RNMF14FTD1K82 features a reinforced construction, improved thermal capacity, and anti-vibration features, ensuring high-quality and durability even under extreme temperatures and vibration conditions. The thick film process used to create the resistor also makes it highly reliable, enabling a high resistance tolerance and tight terminal separation.

RNMF14FTD1K82 Application Field

The RNMF14FTD1K82 is used in a wide variety of applications, ranging from automotive electronics, power supplies, to medical and measurement instrumentation.In automotive electronics, it is commonly used as an on-board power supply and current limiting resistor. The RNMF14FTD1K82 is ideal for this application as it offers a wide resistance range and high-reliability. It can also be used as a voltage-dropping resistor or current-dropping resistor, depending on the purpose of the circuit.In power supplies, the RNMF14FTD1K82 is commonly used as a power regulation resistor. As the resistance value is adjustable, it can be used to regulate the current of the circuit with great precision. This makes it ideal for applications such as DC/DC converters or switching power supplies.In medical and measurement instrumentation, this resistor is often used as a calibration resistor, as the extended resistance range allows for precise calibration of instruments. It can also be used as a protection resistor against overloads or transients in certain medical devices.

Working Principle

The working principle of the RNMF14FTD1K82 is simple: when a current flows through the device, it causes a voltage drop across the resistor, limiting the current in the circuit. The voltage drop is determined by the resistance value of the device. The resistance value can be adjusted by adding or removing resistive material from the device.The RNMF14FTD1K82 uses a thick film process to create the resistive material. During the process, the resistor element is created by sintering special metallic particles with glass into a paste. This paste is then cured onto a ceramic substrate. The resistor is then given its final shape and is ready for use in the circuit.

Conclusion

The RNMF14FTD1K82 is a through hole resistor that is highly reliable and has an extended resistance range. It is used in a wide variety of applications such as automotive electronics, power supplies, and medical and measurement instrumentation. Its working principle is simple: it uses a thick film process to create a resistive material and causes a voltage drop when a current passes through the device, limiting the current in the circuit.
