# RN55C2003FR Product Series Introduction

## 1. Overview
The RN55C2003FR product series represents a cutting - edge range of electronic components engineered to meet the diverse and demanding requirements of modern electronic applications. These components are designed with precision and high - quality materials, offering a combination of reliability, performance, and versatility.

## 2. Key Specifications

### Resistance Value
The "2003" in the model number indicates a specific resistance value. In the standard resistor coding system, this translates to a resistance of 200 x 10³ ohms, or 200 kΩ. This resistance value is carefully calibrated during the manufacturing process to ensure high accuracy, typically with a tolerance level that can be as low as ±1%. This high - precision resistance makes the RN55C2003FR suitable for applications where exact resistance values are crucial, such as in voltage dividers, signal conditioning circuits, and precision measurement equipment.

### Power Rating
The RN55C2003FR series is designed to handle a certain amount of power. The power rating is an important specification as it determines the maximum amount of electrical power the resistor can dissipate without overheating. These resistors usually have a power rating that is appropriate for a wide range of general - purpose and some high - performance applications. For example, they may have a power rating of 0.25W or 0.5W, which allows them to be used in circuits with moderate power requirements, such as in consumer electronics, industrial control systems, and automotive electronics.

### Temperature Coefficient
The temperature coefficient of resistance (TCR) is a measure of how much the resistance of the component changes with temperature. The RN55C2003FR series features a low TCR, which means that its resistance remains relatively stable over a wide temperature range. This is essential for applications where the operating temperature can vary significantly, such as in outdoor electronic devices or in industrial environments with high - temperature machinery. A low TCR helps to maintain the accuracy and stability of the circuit performance, reducing the need for temperature compensation circuits in many cases.

## 3. Construction and Materials

### Substrate
The resistors in the RN55C2003FR series are built on a high - quality ceramic substrate. Ceramic substrates offer excellent electrical insulation properties, high thermal conductivity, and mechanical stability. The high thermal conductivity helps to dissipate heat generated during operation, preventing the resistor from overheating and ensuring long - term reliability. The mechanical stability of the ceramic substrate also makes the resistors more resistant to physical shock and vibration, which is important in applications where the components may be subject to rough handling or harsh environmental conditions.

### Resistance Element
The resistance element is made of a special metal - film material. Metal - film resistors are known for their high precision, low noise, and good frequency response. The metal - film technology allows for a very thin and uniform layer of resistive material to be deposited on the ceramic substrate, which enables precise control of the resistance value. This results in resistors with excellent linearity and low temperature coefficients, making them suitable for high - performance applications.

### Terminations
The terminations of the RN55C2003FR resistors are made of high - quality metal materials, such as tin - plated copper. These terminations provide good electrical conductivity and mechanical strength. The tin - plating helps to prevent oxidation and corrosion, ensuring reliable electrical connections over the lifetime of the component. The mechanical strength of the terminations also allows for easy soldering onto printed circuit boards (PCBs), making the resistors compatible with standard PCB assembly processes.

## 4. Applications

### Consumer Electronics
In consumer electronics, the RN55C2003FR series is widely used in devices such as smartphones
