[Explanation of the Cause of Capacitor Failure] An electrolytic capacitor installed horizontally has burst.

[Explanation of the Cause of Capacitor Failure] An electrolytic capacitor installed horizontally has burst.

A structure that eliminates the filler material and fixes the element with ribs has been adopted! The installation method has been changed to be at the "12 o'clock position"!

We would like to introduce a case where a horizontally mounted screw terminal aluminum electrolytic capacitor failed and the sealing part burst. The failed screw terminal aluminum electrolytic capacitor was mounted horizontally with the pressure relief valve positioned at the "6 o'clock" direction. When a capacitor deteriorates or fails, the temperature of the capacitor element rises rapidly, causing gas to be generated inside. This capacitor uses a filler material to secure the element, and as the element temperature increases, this filler material softens and flows, blocking the pressure relief valve. As a result, the smooth operation of the pressure relief valve was hindered, leading to a crack in the sealing part. [Countermeasures] - Change the mounting method so that the pressure relief valve of the aluminum electrolytic capacitor is positioned at the "12 o'clock" direction. - Adopt a structure that secures the element with ribs instead of using filler material. *For more details, please refer to the PDF document or feel free to contact us.

[Explanation of the Cause of Capacitor Failure] Electrolytic capacitors connected in series are shorted.

[Explanation of the Cause of Capacitor Failure] Electrolytic capacitors connected in series are shorted.

Increase the rated voltage of the capacitor to reduce the difference in leakage current, and also review the voltage divider resistance value!

We would like to introduce a case where a series-connected aluminum electrolytic capacitor short-circuited. When a capacitor with a high leakage current is included in a capacitor series, the voltage balance can be disrupted, causing the voltage to drift above the rated voltage, which may lead to the capacitor short-circuiting. For this reason, it is recommended to connect resistors (voltage divider resistors) in parallel with each individual capacitor when connecting capacitors in series. However, in this case, the leakage resistances of the individual capacitors varied significantly, causing the voltage divider resistors to not function properly. 【Countermeasures】 - To achieve a uniform voltage distribution across the series-connected individual capacitors, increase the rated voltage of the capacitors to reduce the disparity in leakage currents, and review the values of the voltage divider resistors. - Use capacitors from the same manufacturing lot to align the behavior of leakage currents against temperature changes and voltage fluctuations. - This can help stabilize the voltage division. *For more details, please refer to the PDF document or feel free to contact us.

[Explanation of the Cause of Capacitor Failure] Capacity loss occurred, and then it became open.

[Explanation of the Cause of Capacitor Failure] Capacity loss occurred, and then it became open.

As a countermeasure, please ensure that the actual current applied is below the allowable value!

When the foil electrode type film capacitor was changed to a vapor-deposited electrode type film capacitor with the same rating, the capacitor failed open. Even with the same rating, the vapor-deposited electrode type is set to have a lower pulse current tolerance than the foil electrode type. This is because the vapor-deposited electrode has a higher resistance and generates more heat than the foil electrode. When a steep pulse current or high-frequency current is applied to the vapor-deposited electrode type, the capacitor heats up, causing the dielectric film to thermally shrink, which damages the junction between the vapor-deposited electrode and the collector electrode (metal spraying), leading to an unstable connection. Ultimately, the connection between the two becomes disconnected and fails open, but when high voltage is applied, sparks may occur, potentially causing a fire. [Countermeasures] ■ Ensure that the actual applied current remains below the allowable value. *For more details, please refer to the PDF document or feel free to contact us.

[Explanation of the Causes of Capacitor Failure] A resin-coated capacitor ignited.

[Explanation of the Causes of Capacitor Failure] A resin-coated capacitor ignited.

When applying an overcoat, please select the resin considering the thermal expansion coefficient of the substrate!

The lead wire film capacitor mounted on the substrate was coated with resin. The connection between the capacitor element and the lead wire sparked, causing the capacitor to ignite. The cause was that the coated resin repeatedly expanded and contracted, applying stress to the capacitor. As a result, the connection between the capacitor element and the lead wire experienced stress and delaminated, leading to a spark when voltage was applied, which caused the capacitor to ignite. [Countermeasures] ■ When applying an overcoat, select resin considering the thermal expansion coefficient of the substrate. * For more details, please refer to the PDF document or feel free to contact us.

Introduction to Capacitors: How Capacitors Work

Introduction to Capacitors: How Capacitors Work

Compact, high-capacity, high-voltage, and long-lasting! Capacitors have a simple yet very important role.

I will introduce the mechanism and function of a capacitor. The circuit symbol representing a capacitor consists of two parallel lines. This indicates that the capacitor is made up of two parallel conductive plates. The larger the surface area of the capacitor's electrode plates and the closer the distance between the two plates, the greater the capacity to store electricity. Additionally, the electrode plates are electrically separated by an insulating material, which gives the capacitor the ability to block direct current while storing electricity (capacitance). These materials are generally referred to as dielectrics. 【Functions of a Capacitor】 ■ Stores charge (electricity) ■ Does not allow direct current to pass, but allows alternating current to pass *For more details, please refer to the PDF document or feel free to contact us.
