6 FAQs about [How to judge the pillow capacitor]

How do I choose a capacitor?

You don't check. To choose the capacitor, you go to the manufacturer data sheets of the capacitors, which will have the specifications you need to help you choose. You buy from a reputable distributor, and specify the capacitor you want. That way, counterfeits and substitutions are less likely.

How to measure capacitance & dissipation factor correctly?

The key to measure the capacitance and dissipation factor correctly is the meter settings (see Table 1). Table 1: Frequency and voltage settings for different capacitance range and class types. The voltage settings are very critical for high capacitance capacitors.

Do ceramic chip capacitors depend on test conditions?

Electrical behavior of ceramic chip capacitors is strongly dependent on test conditions, most notably temperature, voltage and frequency. This dependence on test parameters is more evident with Class II ferroelectric dielectrics, and negligible or more easily predictable with Class I formulations.

Should I replace all electrolytic capacitors on a PCB?

Too often we get / give the advice to replace all electrolytic capacitors on a PCB when it starts to malfunction (like in DVD player power supply circuit strange behavior. Need help to understand root cause but here are many more examples). Reason seems to be the huge difference in quality for these capacitors.

How do I know if a capacitor is bad?

You also need to know that the application isn't over-stressing the capacitor. A bad design that leads to excess ripple current or operating temperature or excessive voltage (or some combination of the three) may cause even the best capacitors on the market to fail prematurely.

What is a 35 volt capacitor?

35 volts isn't the operating voltage; it's the maximum voltage allowed on the capacitor before it suffers degradation and shorter life. You don't check. To choose the capacitor, you go to the manufacturer data sheets of the capacitors, which will have the specifications you need to help you choose.
