Below, let's learn how to use **x tantalum capacitors and what problems should be paid attention to when using them.

1.The failure of a capacitor is greatly affected by the ratio of the operating voltage to the rated voltage. When designing the actual circuit, reduce the voltage appropriately to take into account the required reliability.

2.**The x-tantalum container is a polar capacitor, so do not apply reverse voltage, and do not use AC-only circuits.

3.Ripple voltage: Use within the allowable ripple voltage specified by the capacitor.

4.Use ambient temperature.

5.Frequency characteristics: The frequency is in the 10kHz area, and the electrical characteristics of **x tantalum capacitors change significantly, so when using high-frequency circuits, please check the circuit characteristics.

6.Reliability: **The failure rate of tantalum capacitors varies depending on the conditions of use (ambient temperature, applied voltage, circuit resistance, circuit use, etc.), so please thoroughly consider the conditions of use before selecting the appropriate product.

7.Installation: If the **x tantalum capacitor is mounted on a printed circuit board, it will cause deterioration of electrical characteristics and short circuits if it is subjected to excessive mechanical shock or thermal shock load, so please check the actual installation conditions before using it.

8.Use. Measurement.

9.Circuit board cleaning: When cleaning, please remove the flux used in soldering at the same time, quickly remove the acid, alkali, etc., do not leave it behind, the temperature should be below 50 during cleaning, and the total time of ultrasonic, vapor impregnation, etc. should be less than 5 minutes, please note that depending on the conditions of ultrasonic cleaning, the terminal will break.

10.Usage Environment: Do not use in the following environments.

11.Maintenance and spot check: When checking the terminal of the **x tantalum capacitor with a detector, please check the potential and polarity of the detector in advance, if the reverse voltage is applied through the **x tantalum capacitor, it will cause a short circuit, and in addition, when the electrode is contacted during the power on, do not contact the terminals of other components, and do not bend the capacitor.

12.In the event of a malfunction: If there is a foul smell or smoke after powering on, please cut off the power immediately. When burning, do not put your face or hands close to it, as if the capacitor is short-circuited, there will be smoke from the exterior resin and a fire from the tantalum element.

13.In principle, the storage period is 10 years after manufacturing (excluding solderability).
