1. How do you know that a capacitor is tantalum polymer?
Appearance markings: Usually the word "Polymer" is marked, along with the capacitance value, operating voltage, and positive and negative pole identification.
Packaging information: Check the
Technical specifications or data sheet on the product packaging. -
2. What special precautions must be taken when installing tantalum polymer capacitors?
Ensure correct polarity connection: Incorrect polarity will cause immediate damage.
Pay attention to the operating temperature range: Avoid exceeding the recommended operating temperature range.
Protection during welding: Avoid overheating to protect components from damage.
ESD protection: Take appropriate anti-static measures during handling. -
3. Which side of a tantalum polymer capacitor is the positive pole?
Usually, there is a clear mark on the tantalum polymer capacitor to indicate the positive pole, such as a long bar mark or a "+" symbol.
-
4. What causes tantalum polymer capacitors to fail?
Overvoltage operation: Exceeding the rated voltage may cause internal breakdown.
Reverse bias: Connecting the positive and negative terminals in reverse may cause immediate damage.
Overheating: Prolonged exposure to high temperature environments can affect performance and even cause failure.
Mechanical damage: Damage may also be caused by external impact or pressure.
