Frequently Asked Questions

We offer a wide range of capacitors to suit various applications:

  • AC Capacitors: Designed for alternating current applications.
  • Electrolytic Capacitors: High-capacitance capacitors commonly used in power supply filters.
  • Film Capacitors: Stable and reliable capacitors used in signal processing.
  • HVAC Capacitors: Specialized capacitors for heating, ventilation, and air conditioning systems.
  • Motor Start Capacitors: Provide the initial boost to start motors.
  • Pump Capacitors: Tailored for pump motor applications.
  • Panasonic Capacitors: High-quality capacitors from a trusted brand.
  • High Voltage Capacitors: Designed for high voltage applications.
  • Electronic Capacitors: Used in various electronic circuits for storing and releasing energy.

The lifespan of an AC capacitor varies based on usage and environmental conditions:

  • Typical Lifespan: 10 to 20 years.
  • Factors Affecting Lifespan:
  1. High Temperatures: Excessive heat can shorten lifespan.
  2. Frequent Cycling: Frequent on/off cycles can cause wear.
  3. Poor Maintenance: Lack of regular maintenance can lead to premature failure.

Regular inspections and maintenance can help extend the life of your capacitor.

Yes, some capacitors are polarized, meaning they have a positive and negative terminal.

  • Electrolytic Capacitors: Typically polarized; ensure correct orientation during installation.
  • Film and Ceramic Capacitors: Generally non-polarized and can be connected in any direction.

Incorrect polarity can damage the capacitor and the circuit.

Testing capacitors can help determine their condition:

  • Visual Inspection: Look for signs of bulging, leakage, or discoloration.
  • Multimeter Test: Use a multimeter with capacitance measurement capability to check the capacitance value.
  • ESR Meter: Measure the Equivalent Series Resistance (ESR) to assess the capacitor's health.

Always discharge the capacitor before testing to avoid electrical shock.

To select the appropriate AC capacitor:

  • Check Specifications: Refer to the old capacitor's label for capacitance (µF), voltage rating, and type.
  • Match Type: Ensure the type (start, run, dual) matches your system's requirements.
  • Consider Brand: Opt for reputable brands like Panasonic for quality assurance.

If in doubt, consult a professional technician or contact our customer support for guidance.

  • Start Capacitors: These are used to provide an initial boost of energy to start motors in HVAC systems. They are only active when the motor starts.
  • Run Capacitors: These provide continuous power to keep the motor running once it’s started. They are constantly active while the motor is in operation.

Some systems use a dual capacitor, which combines both start and run functions into one unit.

Yes, you can replace a faulty capacitor with one of a different brand, as long as the new capacitor matches the required capacitance (µF), voltage rating, and type (start, run, or dual). However, opting for reputable brands, like Panasonic or trusted HVAC-specific capacitors, ensures reliability and performance.
