Through Hole Resistors - RNF18FAD100K application field and working principle

Through hole resistors, sometimes referred to as through-hole lead resistors, are the preferred choice in the industry and are often used in circuits where ventilation or shock resistance is a priority. Due to their design, through-hole lead resistors may be more expensive than surface mounted components with comparable specifications, but their durability and reliability make them well suited for critical applications. RNF18FAD100K is one of the most popular resistors used in through hole resistors.

RNF18FAD100K is a 2W resistor with a wide temperature range (-55°C to +155°C). The rated resistance is very consistent over a wide temperature range, with a resistance tolerance of just ±0.25%. RNF18FAD100K is an excellent choice for applications that require very precise resistance values.

RNF18FAD100K is suitable for flow soldering, dip soldering, and reflow soldering. It is important to note that too much heat can cause damage to the resistor, so temperature control is paramount during soldering. It’s also important to note that while RNF18FAD100K can be flow soldered, the maximum temperature should not exceed 260°C.

The basic construction of RNF18FAD100K consists of a resistive element coated with a protective material, such as ceramic, epoxy, or glass. The type of resistive element depends on the application; some models use carbon, while others rely on metal alloy or ceramic composition. The specific resistive material and construction also affects the temperature coefficient, which indicates how the resistance of the device changes over changes in temperature.

RNF18FAD100K’s temperature coefficients vary greatly, but the most common values range from ±200 ppm/°C to ±2000 ppm/°C. Positive coefficients indicate that as temperatures increase, resistance will also increase, while negative coefficients indicate that resistance will decrease. Typically, the temperature coefficient of a resistor is labeled on the device and/or its datasheet.

The primary reason RNF18FAD100K is so popular is its extremely reliable operation. It is designed to withstand extreme temperatures, and its impressive tolerance, thermal stability, and voltage range make it an ideal choice for a wide variety of applications. It is commonly used in automotive, aviation, telecommunications, and medical industries. Common applications include temperature sensing, current sensing, voltage regulation, and power dissipation.

In general, RNF18FAD100K is a reliable and durable through-hole lead resistor. Its wide temperature range, precision resistance tolerance, and high voltage ratings make it a popular choice in any application that requires accurate and reliable performance. For design engineers, RNF18FAD100K will help ensure that any application requiring precise resistance measurements will be effective, reliable, and safe.
