Q1: What are bolt type aluminum electrolytic capacitors used for?
A1: Bolt-type aluminum electrolytic capacitors are mainly used in high-power industrial equipment, such as inverters, UPS, welding machines, large switching power supplies and power transmission equipment. They are designed for high ripple current and large capacitance requirements.
 
Q2: What is the lifespan of bolt aluminum electrolytic capacitors?
A2: Service life depends on working temperature and ripple current. Under rated operating conditions, our capacitors can reach 5,000 hours to 12,000 hours. Higher ambient temperature will shorten capacitor service life, following the 10°C rule.
 
Q3: What are the common failure modes of bolt electrolytic capacitors?
A3: Typical failure modes include capacitance degradation, increased ESR, electrolyte dry-out, bulging, electrolyte leakage and safety vent rupture. Overvoltage, overheat and excessive ripple current are the main causes.
 
Q4: Can I install the capacitor in any direction?
A4: No. Aluminum electrolytic capacitors are polarized. Positive and negative terminals must be connected correctly. Reverse connection will cause leakage, bulging or even explosion.
 
Q5: What is your MOQ?
A5: Small sample orders are acceptable. For mass production, MOQ depends on model specifications. Please contact us for details.
 
Q6: Can you customize specifications for bolt capacitors?
A6: Yes. We can customize capacitance, voltage, dimension and terminal requirements according to customer’s drawings.
 
Q7: What certificates do your capacitors have?
A7: Our products comply with relevant safety standards. Test reports can be provided upon request.
