Even multilayer ceramic capacitors come in a variety of types depending upon the raw materials used and the shape of each capacitor. Npo capacitors are available at mouser electronics.

Npo capacitor frequency response. Mouser offers inventory pricing datasheets for npo capacitors. For low frequency filtering 60 120hz a large value of capacitance is necessary. Class i also known as npo temperature compensating capacitors suitable for resonant circuits where stable capacitance and high q are necessary.
Npo stands for negative positive 0 ppm0c meaning that for negative or positive shifts in temperature the capacitance changes 0 part per million meaning that it has a flat response across a wide range of temperatures. A self resonant frequency response comparison between common integration capacitors and mlv options was performed. At high frequencies a multilayer ceramic capacitor has low impedance and exhibits excellent frequency characteristics.
This enables accurate frequency response over a wide temperature range in for example resonant circuits. C0g np0 ceramics offer one of the most stable capacitor dielectrics available. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.
These capacitors have a capacitance variation dcc of 054 within the temperature range 55 to 125 0c. At this frequency the capacitor is useless as a filter. They are made of non ferro electric materials yielding superior stability and low volumetric efciency.
For this reason dc power supplies often use a parallel combination of capacitors. The frequency characteristics of a capacitor differ greatly from one type of capacitor to another. Capacitance change with temperature is 0 30ppm0c which is less than 03 c from 550c to 1250c.
The series inductance of the capacitor also raises the impedance limiting its ability to pass ac current. Capacitance drift or hysteresis for c0g np0 ceramics is negligible at less than 005 versus up to 2 for films. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.

In this exercise the minimum to maximum capacitance values available in mlcc and mlv case sizes from 0201 to 1210 were tested and plotted in a case size by case size mannersee figure 3a and 3b.
