1. Introducció
This manual provides essential information for the proper handling, installation, and application of the KEMET T591D107M010ATE040 Tantalum Polymer Capacitor. The T591 series offers high capacitance, low ESR, and stable performance across a wide temperature range, making it suitable for various demanding electronic applications.
Figure 1: KEMET T591D107M010ATE040 Tantalum Polymer Capacitor. This image shows the compact, rectangular surface-mount component with markings "107", "10KP", and "528" on its top surface, indicating its capacitance, voltage, and manufacturing code. The silver-colored terminals are visible on the ends.
2. Installation and Handling
Proper handling and installation are crucial for the optimal performance and longevity of the capacitor. These components are sensitive to excessive heat and mechanical stress.
2.1. Emmagatzematge
- Store capacitors in their original packaging in a dry, cool environment, away from direct sunlight and corrosive gases.
- Maintain storage temperature between 5°C and 35°C and relative humidity below 60%.
2.2. Consideracions de muntatge
- This capacitor is designed for surface mount technology (SMT). Ensure proper pad layout on the Printed Circuit Board (PCB) according to industry standards (e.g., IPC-7351).
- Observe polarity: Tantalum capacitors are polarized. The positive terminal is typically marked with a bar or a plus sign on the capacitor body. Incorrect polarity can lead to component failure.
- Avoid excessive mechanical stress during placement. Use pick-and-place machines with appropriate nozzle pressure.
2.3. Soldering Guidelines
Reflow soldering is the recommended method for mounting. Wave soldering is generally not recommended for polymer capacitors due to thermal stress.
- Reflow Profile: Adhere strictly to the recommended reflow soldering profile provided by KEMET. Exceeding maximum temperature or dwell time can damage the component.
- Temperatura màxima: Typically, peak temperature should not exceed 260°C for a maximum of 10 seconds.
- Xoc tèrmic: Minimize rapid temperature changes during preheating and cooling phases to prevent thermal shock.
- Neteja: If cleaning is required after soldering, use mild, non-aggressive cleaning agents. Avoid ultrasonic cleaning, which can cause mechanical damage.
3. Operating Conditions and Application Notes
To ensure reliable operation, the capacitor must be used within its specified electrical and environmental limits.
3.1. Voltage Sol·licitud
- Voltage (VR): Do not apply a continuous voltage superant el volum nominaltage de 10V.
- Surge Voltage (VS): Brief surges up to 13V are permissible, but continuous operation at surge voltage is not allowed.
- Reducció: For optimal reliability, especially in high-temperature or high-ripple current applications, apply a voltage derating. KEMET recommends derating by 10% to 20% of the rated voltage.
3.2. Corrent ondulat
- Ensure that the ripple current applied does not exceed the maximum permissible ripple current specified in the datasheet, considering the operating frequency and temperature. Excessive ripple current can lead to overheating and premature failure.
3.3. Interval de temperatura
- Operate the capacitor within its specified operating temperature range, typically -55°C to +105°C. Performance characteristics, such as capacitance and ESR, will vary with temperature.
4. Manteniment
KEMET T591 series capacitors are passive components designed for long-term reliability and typically require no routine maintenance once properly installed and operated within specifications. However, periodic inspection of the PCB assembly is recommended.
- Inspecció visual: Periodically inspect the capacitor and surrounding PCB area for any signs of physical damage, discoloration, or solder joint degradation.
- Control ambiental: Ensure the operating environment remains within specified temperature and humidity limits to prevent long-term degradation.
- Dust and Contaminants: Keep the electronic assembly free from excessive dust and conductive contaminants, which can lead to short circuits or performance issues.
