We often get questions as to the difference between similar capacitors from the same manufacturer such as the RH221C106MAARA3 and RH221C106MA3RA3 ceramic capacitors from KYOCERA AVX. As seen on the snippet from the datasheet below, the only difference between these two parts is the packaging they come to us in.
The RH221C106MAARA3 is on a tape and reel and the RH221C106MA3RA3 comes in a waffle pack.
This part numbering guide applies to the entire RH series of ceramic capacitors from Kyocera.
Below are the Style/Size codes.
Please note only the RH21 and RH22 are AEC-Q200 compliant.
