## 2. Key Features
### 2.1 High Precision
One of the standout features of the RK73H1JTTD2491F series is its high precision. With a tolerance of ±1% (indicated by the "J" in the part number), these resistors offer extremely accurate resistance values. This precision is crucial in applications where even the slightest deviation in resistance can lead to significant performance issues, such as in precision measurement equipment, sensor circuits, and audio amplifiers.
### 2.2 Low Temperature Coefficient
The resistors in this series have a low temperature coefficient. This means that their resistance value changes very little with variations in temperature. A low temperature coefficient ensures stable performance over a wide temperature range, making the RK73H1JTTD2491F suitable for use in environments with fluctuating temperatures, such as automotive electronics, industrial control systems, and outdoor communication equipment.
### 2.3 High Power Rating
Despite their relatively small size, the RK73H1JTTD2491F resistors are capable of handling a certain amount of power. The power rating is carefully designed to meet the needs of different applications without overheating. This high - power handling capability allows them to be used in circuits where higher power dissipation is required, such as power supplies and motor control circuits.
### 2.4 Compact Size
The series features a compact form factor, which is beneficial for modern electronic devices that are constantly striving for miniaturization. The small size of the RK73H1JTTD2491F resistors enables them to be easily integrated into densely populated printed circuit boards (PCBs), saving valuable board space and allowing for more complex circuit designs.
## 3. Technical Specifications
### 3.1 Resistance Value
The specific resistance value of the RK73H1JTTD2491F is 2490 ohms (the "2491" in the part number follows the EIA - 96 resistor coding system, where the first three digits represent the significant figures and the last digit is the multiplier. So, 249 × 10^1 = 2490 ohms). This value is carefully calibrated during the manufacturing process to ensure accuracy within the specified tolerance.
### 3.2 Power Rating
The power rating of the RK73H1JTTD2491F is typically in the range suitable for medium - power applications. The exact power rating depends on factors such as the operating temperature and the PCB layout. However, it is designed to handle a sufficient amount of power to meet the requirements of most common electronic circuits.
### 3.3 Operating Temperature Range
These resistors can operate within a wide temperature range, typically from - 55°C to +125°C. This broad operating temperature range makes them suitable for use in harsh environments, including automotive under - the - hood applications, aerospace systems, and industrial machinery that may be exposed to extreme temperatures.
### 3.4 Voltage Rating
The voltage rating of the RK73H1JTTD2491F is specified to ensure safe and reliable operation. It is designed to withstand a certain maximum voltage without breakdown or significant performance degradation. This voltage rating is an important consideration when selecting the resistor for high - voltage applications.
