Lead-Free Terminations

All standard terminations (JDI termination code "V") of our SMT components consist of 100% Matte Tin plating over a Nickel barrier. Components with these terminations are capable of a 260°C maximum reflow temperature for a duration of 5 seconds and compatible with most common lead-free solder processes. Tin Whisker test results are published in the Johanson Technical Note: Tin Whisker Testing

*Sn-Pb Terminations

In response to specific industry and customer requests, Johanson Dielectrics produces a limited amount of product featuring Tin-Lead (Sn-Pb) Terminations (JDI termination code "T") and flexible Tin-Lead Termination (JDI termination code “W”). These products are non-RoHS compliant due to the Pb constituent in the termination as required in certain specialty applications, e.g., Military & Space.

Legacy RoHS Compliant P/N Suffix

In 2005 a Johanson part number suffix of "-****-RC" assisted customers in identifying compliant and non-compliant inventory during their transition to RoHS compliancy. The "RC" suffix is no longer necessary for surface mount devices to ensure compliance and should not be utilized for new designs. JDI will continue to support these legacy part numbers for the benefit of customers with these part numbers on current AVLs / BOMs.
