Mounting
All encased capacitors will pass the Resistance to Soldering Heat of MIL-STD-202, Method 210, Condition C. This test
simulates wave solder topside board mount product. This demonstration of resistance to solder heat is in accordance with
what is believed to be the industry standard. More severe treatment must be considered reective of an improper soldering
process.
The above gure is a recommended solder wave prole for both axial and radial leaded ceramic capacitors.
