Through Hole Resistors – RN55D6812FB14

Through-hole resistors are passive electronic components which are used for limiting current, voltage, or both in electrical circuits. They differ from surface mount resistors since they are designed to be installed in through hole holes in the circuit board. Specifically, the RN55D6812FB14 is a precision, 1206-size surface mount resistor package with low temperature coefficient, low noise, and low profile.

General Specifications:

• Resistance value range: 0.25Ω - 0.68Ω
• Rated voltage: 75V
• Power rating: 0.25mW
• Resistance tolerance: ±10%
• Temperature coefficient: 0.15 ppm/°C
• Operating temperature range: -40°C to +125°C
• Package size: 1206 size

Application Fields:

Given its excellent temperature coefficient, low noise levels, and other characteristics, RN55D6812FB14 resistors are used in many different types of electronic applications. Its surface mount design makes it suitable for applications which require circuit boards with higher density and smaller footprint. This type of resistor is often used in amplifiers, motor control, medical electronics, automotive electronics, test and measurement equipment, and other high-precision applications.

Working Principle:

As a passive element, the RN55D6812FB14 resistor works by reducing the voltage or current level traveling through it. In essence, an electrical current passes through the resistor, and a portion of this current is “lost” due to the resistor’s resistance. The current and voltage levels through the resistor will then be lower than the input levels, allowing the designer to limit the amount of current or voltage passing through the end-point.

In addition to its voltage/current-limiting capabilities, the RN55D6812FB14’s low-temperature coefficient allows it to remain relatively stable over wide temperature ranges. Furthermore, its low noise levels make it suitable for noise-sensitive applications such as those found in medical, measurement, and automotive equipment.

Conclusion

The RN55D6812FB14 is a high-precision, surface mount through hole resistor which is widely used in many different types of electronic applications. Its low-temperature coefficient, low noise levels, and other attributes make it particularly well-suited for applications such as amplifiers, motor control, medical electronics, and automotive electronics. With its ability to limit voltage and current, the RN55D6812FB14 is an essential component in many electronic designs.
