Questions about this product
- What are these 3.9uF capacitors typically used for?
- These AEROVOX 3.9uF capacitors are ideal for audio crossover networks, power supply filtering, and motor run/start circuits. They also work well in timing and oscillator circuits that need stable pulse generation.
- Can I use these capacitors in circuits with higher voltages than 100V?
- No, these capacitors are rated for a maximum of 100 V DC. Using them in circuits with higher voltages could damage the component and cause circuit failure. Always match the capacitor's voltage rating to or above your circuit's operating voltage.
- What material is used for the dielectric in these capacitors?
- These capacitors feature a metallized polyester film construction for the dielectric. This material provides stable capacitance over temperature and offers superior self-healing properties. The case itself is made from flame retardant epoxy resin.
