As the capacity of multilayer ceramic capacitors increases, the number of cases in which multilayer ceramic capacitors are being used in areas that were previously unconsidered is also on the increase.
In the marketplace, we are seeing practical applications being promoted to improve the efficiency of mainly electric power converters as a result of higher frequencies being applied to switching elements and these elements being driven at higher temperatures. In addition, multilayer ceramic capacitors are being adopted more and more for their impedance characteristics at high frequencies and compatibility at high temperatures.
Another key point in their adoption is that downsizing and cost reductions can be achieved due to their compatibility with surface-mounted products.
These materials provide actual examples of the differences between film capacitors and multilayer ceramic capacitors, and how downsizing and cost reductions can be achieved.
Please do read our tips for increasing your design freedom.
Key reasons for recommending multilayer ceramic capacitors
1) Downsizing is possible
2) Compatibility with high-temperature, high-humidity environments
3) Surface-mounting compatibility
Comparison between film capacitors and multilayer ceramic capacitors
This table shows a comparison between multilayer ceramic capacitor and film capacitor products with the same voltage and capacity.
From this table, you can see that multilayer ceramic capacitors are considerably smaller.
Resistance to high-temperature environments and high humidity
With multilayer ceramic capacitors, 125°C is set as the standard guaranteed temperature.
Also, we have tested our products for humidity resistance in high 85% or 95% humidity environments in reliability tests.
Advantages when multilayer ceramic capacitors are used
There are a number of advantages in choosing multilayer ceramic capacitors: Components can be downsized, substrates can be downsized as a result of the high degree of freedom in the layout of mounted components, and humidity exclusion measures can be reduced as a result of their outstanding humidity resistance.
Example of circuit used
Example of application: Air conditioner, general-purpose inverter, power converter
Snubber capacitors (C1) are required to have high-frequency noise removed.
