What is the MSL level of the ceramic capacitors? | Capacitors …
Evaluations performed by Murata revealed the MSL of the chip multilayer ceramic capacitor is 1 and the MSL of the resin mold surface applied type ceramic capacitor (DK1, EVA Series) is 3. Since products compatible to reflow soldering are applicable to MSL, products dedicated to flow soldering, such as parts with leads, are not applicable.
Analysis of the influence of soldering parameters on multi-layer ...
Multilayer ceramic capacitors (MLCCs) are small, inexpensive surface-mounted electronic components with high capacitance. MLCC is used in two major applications, one is resonant circuits and filters, and the other is power supply bypass and decoupling (Pan and Randall 2010) cause of the strong points, it is used in almost all …
•The manufactures do not recommend hand-soldering of ceramic capacitors, and the "failing parts" were hand soldered. •This is the first instance we have seen of cracked capacitors making it through I&T undetected and becoming anomalous on-orbit. •In all cases the cracks on TIRS did not propagate to the surface of the part.

Cracking Problems in Low-Voltage Chip Ceramic Capacitors
Cracking remains the major reason of failures in multilayer ceramic capacitors (MLCCs) used in space electronics. Due to a tight quality control of space-grade components, the probability that as manufactured capacitors have cracks is relatively low, and cracking is often occurs during assembly, handling and the following testing of the systems.
