Notes
(1) Case sizes 1111, 1210 to 1812 with a thickness > 0.049" (1.24 mm) and case sizes 1825 and larger should NOT be wave soldered.
(2) Termination code “E” is for conductive epoxy assembly, contact [email protected] for availability.
(3) CDR, DSCC, and MIL-PRF-123 part numbers only.
(4) CDR “U” termination code: Base metallization-barrier metal-solder coated (tin/lead alloy, with a minimum of 4 % lead).
Solder has a melting point of + 200 °C or less. Solder coat thickness is a minimum of 60 microinches.
• Solder iron techniques are not recommended. For more information on soldering visit www.vishay.com/doc?45034.
• Contact [email protected] with respect to specific part number requirements.
(5) Terminations code “F” and “M” may exhibit high wetting angles and lower fillet heights as compared to barrier plate terminations such as
X-term. Contact [email protected] with respect to specific requirements.
(6) For “C” termination solder coverage should be at least 90 % of the terminal critical areas in soldering.
