Production Processes

  • Winding
    The process begins with winding the metallized film to create the capacitor's core.
  • Hot Pressing (Flat Core)
    Hot Pressing (Flat Core)
    Here, the wound core undergoes hot pressing to flatten it. This step is important for shaping the capacitor and can also influence its electrical characteristics.
  • Wrapping
    A protective wrapping is applied to the capacitor for insulation and to maintain structural integrity.
  • Gold Spraying
    Gold Spraying
    Gold is sprayed onto the capacitor leads to improve electrical contact and corrosion resistance.
  • Ring Removal and Edge Rolling
    Ring Removal and Edge Rolling
    Any holding rings are removed and the edges of the capacitor are rolled for a smooth finish.
  • Soldering and Potting and Baking
    Soldering and Potting and Baking
    The leads are soldered to the terminals, and the capacitor is sealed with a resin or glue (potting) and then baked to cure the sealant.
  • Reeling and External Inspection
    Reeling and External Inspection
    The capacitors are wound onto reels for handling and an external inspection is conducted to check for manufacturing defects.
  • Testing
    The capacitors undergo a series of tests to ensure they meet the necessary electrical specifications.
  • Printing
    Capacitors are printed with necessary information including capacitance, voltage rating, and manufacturer details.
  • Lead Cutting and Taping
    Lead Cutting and Taping
    Leads are trimmed to the appropriate length and capacitors may be taped together in strips for automated installation.
  • Full Inspection (Safety Regulation)
    Full Inspection (Safety Regulation)
    A comprehensive inspection is conducted in accordance with safety regulations to ensure all capacitors are compliant.
  • Final Quality Control (FQC)
    Final Quality Control (FQC)
    A final quality check is performed to ensure each capacitor meets the company's standards.

CBB61 Capacitor Industry knowledge

What is the general rated voltage of CBB61 capacitor? How does this voltage rating affect its use in electric motors?

The rated voltage of CBB61 capacitors generally varies according to different products and specifications, but common rated voltages are 450VAC and 500VAC. This rated voltage represents the highest voltage that the capacitor can withstand, that is, the capacitor should not exceed this voltage value during normal operation.

The rated voltage has an important influence on the application of CBB61 capacitors in motors. First, it determines whether the capacitor can be safely used in a specific motor circuit. If the operating voltage of the motor circuit exceeds the rated voltage of the capacitor, the capacitor may be damaged or even cause a safety accident. Therefore, when selecting a CBB61 capacitor, you must ensure that its rated voltage matches the operating voltage of the motor circuit.

Secondly, the rated voltage also affects the performance and life of the capacitor. At the rated voltage, the capacitor can maintain the best working condition, provide stable capacitance support, and help the motor start and run smoothly. If the voltage is too high or too low, it may cause the performance of the capacitor to decrease and even shorten its service life.

Therefore, when selecting and using CBB61 capacitors, it is necessary to fully understand its rated voltage and match it according to the actual needs of the motor circuit. At the same time, it is also necessary to pay attention to other parameters of the motor circuit, such as operating current, frequency, etc., to ensure that the selection and application of capacitors can meet the stable operation requirements of the motor.

When selecting a CBB61 capacitor, how should its insulation resistance and self-healing properties be considered?

When selecting CBB61 capacitors, insulation resistance and self-healing properties are two very important considerations. Here are specific considerations regarding these two factors:

Insulation resistance:
Insulation resistance is an important electrical parameter of a capacitor, indicating the insulation performance between the two electrodes of the capacitor. The greater the insulation resistance, the better the insulation performance of the capacitor, the smaller the leakage current, and the higher the safety of the capacitor. Therefore, when selecting a CBB61 capacitor, attention should be paid to its insulation resistance, and capacitors with high insulation resistance should usually be selected.

Self-healing properties:
Self-healing is a unique property of CBB61 capacitors, which means that when the capacitor is subjected to abnormal conditions such as overvoltage and overcurrent, its internal metallized film can self-repair some damage, thereby maintaining the normal operation of the capacitor. Capacitors with strong self-healing properties can reduce the risk of capacitor damage caused by abnormal conditions and improve the reliability and service life of capacitors. Therefore, when choosing CBB61 capacitors, you should choose capacitors with strong self-healing properties.
