Chip capacitors and electrolytic capacitors are common capacitors on the market. Chip capacitors are widely used in various electronic products, with a market share of over 80%. Although electrolytic capacitors are also widely used, their popularity is still inferior to that of chip capacitors. Due to the rapid development of the electronic industry and the trend of miniaturization and chip based development of electronic devices, chip capacitors have become the main force in the market.
       Electrolytic capacitors are capacitors with polarity. When using them, attention must be paid to the polarity of the access circuit. Their capacity can be large, but their high-frequency characteristics are not very good. They are suitable for occasions such as power filtering. Of course, there are also electrolytic capacitors with good high-frequency characteristics - tantalum electrolysis, tantalum point discharge capacitors, which are relatively expensive. Chip capacitors are non polar capacitors, which do not require consideration of access issues. Chip capacitors are small in size, low in price, and have good high-frequency characteristics, such as ceramic chip capacitors, monolithic capacitors, and polyethylene (CBB) capacitors. Chip capacitors are not suitable for large capacities.
       Since they are all capacitors, their essential principles are the same, both with AC resistance and DC resistance, both storing and releasing charges. Let's briefly talk about the differences between the two!
      1. The full name of chip capacitors is multilayer chip ceramic capacitors, which is a general term for most capacitors that can be packaged on a chip. Electrolytic capacitors are a category of capacitance properties.
       2. The biggest difference between electrolytic capacitors is the use of electrolyte inside. Therefore, in order to avoid overpressure and overheating, the neck of the electrolytic capacitor is usually equipped with explosion-proof slots, which can also be used as a simple way to distinguish between solid state capacitors and electrolytic capacitors.
       3. Chip capacitors are divided into two types: non polar capacitors and polar capacitors, and polar capacitors are commonly referred to as electrolytic capacitors.
       4. Chip capacitors are generally relatively small in size, small in capacity, and high in accuracy, while electrolytic capacitors are relatively large in size, capacity, and many types.
     5. Chip capacitors play a significant role in mid to high frequencies, with small size, high voltage withstand, and very low ESR at high frequency resonance points. They are commonly used for mid to high frequency filtering. To filter at low and intermediate frequencies, electrolytic capacitors should be considered first. It should be noted that most electrolytic capacitors have polarity, and the positive and negative electrodes must not be reversed, even if the polarity is accidentally reversed when measuring with an ordinary multimeter, and the capacitance is useless at this time.
