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.
  • Small Packaging

CBB60 Capacitor Industry knowledge

In which major types of motors are CBB60 capacitors most widely used?

CBB60 capacitor, as a metallized polypropylene film capacitor, also known as AC motor electrolytic capacitor, has a series of unique characteristics and advantages.

CBB60 capacitor has the characteristics of high frequency stability, capacitance stability and high voltage resistance, which makes it perform well in different environments and different application scenarios. It can provide high current pulses required for power factor correction and motor starting, improving the starting performance and efficiency of the motor.

CBB60 capacitors usually come in cylindrical, oval or flat shapes, with smaller size and longer service life. This makes it particularly popular in compactly designed motors or electronic equipment. In addition, the CBB60 capacitor has a flame-retardant plastic shell and epoxy resin potting construction, which improves its safety and reliability.

CBB60 capacitors have excellent electrical properties. It has no polarity, excellent frequency characteristics, small dielectric loss, high insulation resistance and stable performance. At the same time, CBB60 capacitors also have a self-healing function, which can self-repair internal damage caused by overvoltage or current shock to a certain extent, thereby extending their service life.

CBB60 capacitors have a wide range of capacities, ranging from a few microfarads to hundreds of microfarads. The rated voltage is usually 250VAC or 450VAC, and the ultimate operating temperature can reach 70°C. This enables CBB60 capacitors to adapt to motors of different specifications and needs.

CBB60 capacitors are widely used in single-phase AC motors, air conditioners, washing machines, fans and other household appliances as well as industrial equipment. In addition, CBB60 capacitors are often used in various electronic equipment such as energy-saving lamp circuits and electronic rectifiers.

When selecting a CBB60 capacitor, how should its rated voltage and capacity be considered?

When selecting CBB60 capacitors, considerations regarding rated voltage and capacity are very important.

The rated voltage is the maximum voltage that the capacitor can safely withstand. When selecting a CBB60 capacitor, make sure its rated voltage is equal to or greater than the operating voltage of the motor. CBB60 capacitors are typically rated for 250VAC or 450VAC, depending on the specific needs and specifications of the motor. If the rated voltage of the selected capacitor is too low, it may cause the capacitor to overheat, be damaged or even explode during operation.

Capacity is the ability of a capacitor to store charge. CBB60 capacitors typically range in capacity from 1μF-100μF, but the specific selection should be based on the starting and running needs of the motor. A capacitor with too small a capacity may not provide enough starting current, making it difficult or impossible to start the motor; while a capacitor with too large a capacity may increase unnecessary cost and volume.

In addition to rated voltage and capacity, other parameters of CBB60 capacitors should also be considered, such as frequency response, temperature range, insulation resistance, etc. These parameters will affect the performance, reliability and safety of the capacitor.
