Is x5r better than x7r

I use a 1210 X5R 25V 10% MLCC for input DC blocking. Supply is drying up and I want to place an order to support production for a while. In performing a Digikey/Mouser search I see there are now X7R devices in the same footprint. I know the X7R will be more stable under DC voltage which is an advantage *if* there is much DC on the input.

Search: Speaker Capacitor Chart. Our wax & paper capacitors are a blend of old and new technology Voltage rating etc The old-fashioned crystal radio in Figure 2 just relied on the capacitance of the antenna itself, but adding a separate capacitor allows for better tuning This means that the capacitor cannot truly discharge instantly, and also that it will heat up when.
r are as follows: NP0 10-100, X7R 2000-5000 and Y5V can be as high as 25000. THE EFFECT OF TIME The effect of time imposes a predictable loss of capacitance in Class II capacitors. For X7R and X5R the loss is calculated at -2.5% per decade hour and for Y5V it is -7% per decade hour.

The typical change of capacity relative service life is less than 0.1%. The capacitance and dielectric loss of NPO capacitors vary with the encapsulation type, and the frequency characteristic of large encapsulation size is better than that of small encapsulation size. The table below shows the range of NPO capacitors available.

A third observation is that, for the same package, the X7Rs always have better temperature sensitivity than X5Rs. I do not know if this holds true universally, but it did seem so in my investigation.

A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are divided into two.

Lets assume that a batch of X7R capacitors fail some test but they pass the tests for X5R, then you might have close to X7R specified components with X5R rating. You might be lucky with a small prototype series and receive boards with good specifications, but what about the normal distribution for a volume production?.

One pretty simple reason is that the tolerance on Y5V tends to be much flakier numerically than X5R or X7R. Typically -20% + 80%. A less obvious and possibly more profound reason is that the change in capacitance versus temperature is very poor on Y5V. Typically at low temperatures and high temperatures the capacitance might halve in value.
