series introduction
# Introduction to the RK73H1JTTD2003F Product Series
## 1. Overview
The RK73H1JTTD2003F product series belongs to the realm of high - precision electronic components, specifically resistors. These resistors are engineered to meet the exacting demands of modern electronic circuits, offering a combination of reliability, accuracy, and performance. They are designed to be used in a wide range of applications, from consumer electronics to industrial control systems.
## 2. Key Features
### 2.1 High Precision
One of the standout features of the RK73H1JTTD2003F series is its high precision. With a tolerance level that can be as low as ±1%, these resistors ensure that the resistance value remains extremely close to the specified nominal value. This high precision is crucial in applications where accurate voltage division, current limiting, or signal conditioning is required. For example, in precision measurement instruments, a small deviation in resistance can lead to significant errors in the measured values. The high - precision nature of these resistors helps to minimize such errors and improve the overall accuracy of the system.
### 2.2 Low Temperature Coefficient
The resistors in this series have a low temperature coefficient of resistance (TCR). A low TCR means that the resistance value of the resistor changes very little with variations in temperature. This is important because temperature fluctuations are common in many electronic environments. In automotive electronics, for instance, the temperature under the hood can vary widely from extremely cold to very hot conditions. A resistor with a high TCR would experience significant changes in resistance, which could affect the performance of the electronic control units. The low TCR of the RK73H1JTTD2003F series ensures stable operation over a wide temperature range, typically from - 55°C to +125°C.
### 2.3 High Power Rating
Despite their relatively small size, the RK73H1JTTD2003F resistors are capable of handling a relatively high power rating. This allows them to dissipate heat effectively and operate without overheating in high - power applications. For example, in power supply circuits, where large amounts of power are being processed, these resistors can be used to limit current and control voltage levels without the risk of thermal damage. The high power rating also contributes to the long - term reliability of the resistors, as they can withstand the stress of continuous operation under high - power conditions.
### 2.4 Compact Size
The series features a compact design, which is highly beneficial in modern electronic devices where space is at a premium. The small form factor allows for more efficient use of printed circuit board (PCB) space, enabling designers to create more densely packed and miniaturized circuits. This is particularly important in portable electronics such as smartphones, tablets, and wearables, where every millimeter of space counts. The compact size also makes the resistors easier to handle during the PCB assembly process, reducing the risk of misplacement or damage.
## 3. Technical Specifications
### 3.1 Resistance Value
The RK73H1JTTD2003F series has a specific resistance value of 2003F, which corresponds to 200 kΩ according to the resistor code system. This value is carefully calibrated during the manufacturing process to ensure high accuracy.
### 3.2 Tolerance
As mentioned earlier, the tolerance of these resistors is typically ±1%. This means that the actual resistance value of a resistor in the series will be within 1% of the nominal 200 kΩ value. For example, the actual resistance could range from 198 kΩ to 202 kΩ.
