Class III ceramic capacitors, like Z5U, offer high capacitance but struggle with temperature stability. The diversity in the characteristics of these capacitors makes them a suitable choice for a variety of applications, establishing them as the most used capacitors in today’s circuits.
Ceramic capacitors are one of the most popular and common types of capacitors. In the early days, ceramic capacitors had very low capacitance, but nowadays, this is not the case. Multilayer ceramic capacitors (MLCC) are used extensively in circuits; their capacitance rating can reach hundreds of microfarads (µF).
Class I ceramic capacitors are characterized by high stability, low losses, and minimal variation in capacitance over various environmental conditions. The most common example of Class I ceramic capacitors are C0G (NP0) and U2J capacitors. Here are the key characteristics of Class I ceramic capacitors, particularly C0G:
The most common examples of Class II ceramic capacitors include X7R and X5R. Here are some general characteristics of Class II ceramic capacitors: Higher capacitance. Moderate temperature stability. Capacitance may vary with changes in applied voltage.
The application above requires 250 μF of capacitance at the input and 450 μF of capacitance at the output. Once the degradation of the ceramic capacitor’s capacitance over-voltage, aging, and temperature is considered, we are required to derate the ceramic capacitor by around 70%.
As touched on earlier, polymer capacitors are excellent for high-frequency applications in comparison to their liquid electrolyte counterparts. While not as good as a ceramic capacitor, they are very close and can offer high capacitance for a similar price and board footprint when compared to the ceramic capacitor option.

They are used for bulk filtering of the power supply voltage. Smaller SMD ceramic or thru-hole ceramic are to filter high frequency noise, thus are very close to their point of use such as a CPU or MPU, or most any IC. Bulk capacitors that smooth low-medium frequency ripple can be inches away, and their high ESR is tolerated.

Live Chat$begingroup$ so only operate the capacitor at 50% its max voltage rating. in general for ceramic capacitors. You might do the same with other capacitors for voltage derating purposes (like tantalums). But C0G/NP0 should be relatively unaffected by DC bias. Most ceramic dielectrics are heavily affected by both DC-bias and temperature.

Live ChatGood ones still last pretty well as long as they''re rated for what you need and you don''t put them next to a blazing hot heatsink or something. Another thing is tolerance is usually pretty bad on electrolytics - if you''re making like a 555 timer, it''s better to use ceramic for the timing capacitor.
