Adhesive Change
e carrier tape cover adhesive process for the Bourns® Model SRN4018 and SRN4026 Semi-Shielded Power
Inductor Series is changing from a heat activated adhesive (HAA) to a pressure sensitive adhesive (PSA). e
new PSA is more resilient than the existing HAA to tearing and breaking during its removal process. e
uniform adhesion of the PSA results in consistent peeling which helps prevent components from popping
out of the carrier during assembly. is change has no impact on the t, function, quality or reliability of the
components. (A ected part numbers are listed in Table 1 on the following page.)
Implementation dates are as follows:
Date that manufacturing of existing packaging method will cease: January 31, 2016

First date code using above changes: 1606
