How Much Do You Know About Aluminum Electrolytic Capacitors?

Aluminum electrolytic capacitors are widely used, but how much do you know about them? Aluminum point capacitor is a medium made of an aluminum cylinder as the negative electrode, containing liquid electrolyte, and a bent aluminum strip inserted as the positive electrode. It also needs to undergo direct current voltage treatment to form an oxide film on the positive electrode as a dielectric. Its characteristics are large capacity, but high leakage, poor stability, positive and negative polarity, suitable for power filtering or low-frequency circuits. When using, do not connect the positive and negative poles in reverse.

WEET How to choose a suitable NP aluminum electrolytic capacitors?

  • Rated voltage:

    The non-polarized Bipolar Aluminum Electrolytic Capacitors and withstand voltage parameters marked on the NP Aluminum Electrolytic Capacitors body are very important and are the most basic content for selecting capacitors;

  • External dimensions:

    The external dimensions are related to weight and pin type. Generally speaking, non-polarized Bipolar Aluminum Electrolytic Capacitors with the same diameter and capacity can be replaced with capacitors with higher heights for capacitors with lower heights;

  • Dielectric loss:

    The energy consumed by a NP Aluminum Electrolytic Capacitors under the action of an electric field is usually represented by the ratio of the loss power to the reactive power of the capacitor, that is, the tangent of the loss angle;

WEET Five things to consider when installing aluminum electrolytic capacitors:

  1. NP Aluminum electrolytic capacitors are not insulated between the aluminum casing and the cathode lead wire. Please note;

  2. Do not apply force to the leads of NP aluminum electrolytic capacitors, otherwise it may cause the leads to break at the welding point with the aluminum stem,

    resulting in open circuits, short circuits, high leakage currents, and other phenomena;

  3. When installing and welding NP aluminum electrolytic capacitors, the temperature should not exceed 260 ℃,

    and the welding time is best controlled within 4 seconds;

  4. When inserting NP aluminum electrolytic capacitors into PCB boards, the hole spacing should match the distance between the capacitor leads.

    Too large or too small can easily cause leakage or high leakage current, ultimately leading to shortened lifespan or open circuit state;

  5. When using non-polarized Bipolar Aluminum Electrolytic Capacitors with explosion-proof valves,

    the explosion-proof valve should be kept at least 3mm away from other mechanisms to ensure that the explosion-proof valve can operate normally.

How To Determine If The NP Capacitor Is Broken?

The following five methods can help you determine whether non-polarized Bipolar Aluminum Electrolytic Capacitors are damaged:
  1. Leakage: After the seal of the electrolytic capacitor is damaged, the electrolyte leaks out,
    causing corrosion of surrounding components or short circuits.
  2. Appearance deformation and expansion: If the shell of an non-polarized Bipolar Aluminum Electrolytic Capacitors deforms,
    expands, or bulges, it is usually due to internal gas production (such as electrolytic decomposition) causing the shell to deform,
    and in extreme cases, it may burst.   
  3. Abnormal sound: If the non-polarized Bipolar Aluminum Electrolytic Capacitors emits abnormal "crackling", "
    popping" discharge sound or "buzzing" dull sound during operation, it indicates that there must be a fault inside the capacitor,
    and it should be stopped immediately for further inspection and treatment or replaced with a new one.
  4. Switch tripping or fuse blowing: If the NP Aluminum Electrolytic Capacitors bank switch experiences an accident tripping or
    high-voltage drop and the fuse is blown, it should be shut down and the capacitor can only be put back into operation after
    confirming that there is no fault.
Method for detecting whether NP capacitors are damaged:
  • Measure capacitance value: Use a multimeter or capacitance meter to measure the actual capacitance of the capacitor and compare it with the nominal value.
    If the difference is large (more than 20%), it may be damaged.
  • Leakage test: Use an insulation resistance tester (megohmmeter) to measure the leakage resistance of the capacitor.
    If the leakage resistance value is significantly low, it indicates that the capacitor may have leakage problems.
  • Short circuit and open circuit test: Use a multimeter to measure whether the capacitor is short circuited or open circuited.
    If it displays as short circuited (resistance close to 0 ohms) or open circuited (resistance infinite), the capacitor is damaged.
  • Equivalent series resistance (ESR) test: Use an ESR tester to measure the equivalent series resistance of a capacitor.
    If the ESR value is high, it indicates that the internal losses of the NP Aluminum Electrolytic Capacitors have increased and may be damaged.
