RECOMMENDED REFLOW PROFILE

Vishay OS-CON has different characteristics against soldering heat from conventional aluminum electrolytic capacitors or

tantalum capacitors because of its unique materials and structure.

Please note the following points on soldering of Vishay OS-CON 94SVPD series to draw out the best performance.

Note

• All temperatures are measured on the topside of the Al-can and terminal surface.

Attention:

Reflow soldering may reduce the capacitance of products before or after soldering even if soldering conditions stipulated in

Recommended Reflow Condition are met. Though the actual reflow conditions are subject to change depending on the kind of

reflow soldering method, please be aware that the peak temperature at the top of Al-case and electrode terminals should not

exceed peak temperature. Particular notice should be given to the time that Vishay OS-CON is heated at 200 °C or higher during

reflow. Be aware that soldering considerably deviating from these conditions will cause problems such as a 50 % reduction in

capacitance, and a considerable increase in leakage current.

The leakage current value may increase (from a few μA to a few mA) even within the above conditions. When the Vishay OS-CON

is used in a DC circuit, the leakage current will decrease gradually through self-recovery after voltage is applied. If your reflow

profile (reflow temperature, number of reflows, etc.) deviates from the above conditions for mounting the 94SVPD series, please

consult with Vishay OS-CON.
