The production process for the Bourns Model SRF1260 and SRF1280
Series Dual-Winding Shielded Power Inductors will be modified to
reduce the amount of epoxy applied between the inductor core and
shield. Currently, the inductor core and shield are held
together with epoxy that is manually applied completely around
the core. The production process will now be automated to apply
the epoxy in four spots to bond the core and shield.

This Product Change Notification reflects an anticipated
positive change to reliability. The reduction in the amount of
epoxy in between the core and shield, which will create free
space for material thermal expansion, should help reduce the
risk of core cracking during the reflow soldering process.

Implementation dates are as follows:
Date deliveries of modified products will begin: May 1, 2013
Date manufacturing of existing product will cease: April 30,2013
The first date code using the above changes will be 1314.

Qualification test data is available upon request.
