Non-shielded Power Inductor Model SDR1005

and Shielded Power Inductor Model SRR1005

Mounting Base Material Change

Effective for manufacturing date code 1021 and later, the mounting base material Liquid Crystal

Polymer (LCP) used on all

SDR1005

and

SRR1005

power inductor models has been changed to

Diallyl Phthalate (DAP).

Recently, Bourns discovered a deformation of the LCP mounting base on a few SDR and SRR1005

models after normal IR reﬂ ow soldering processing. As a result, Bourns has implemented a change

to use DAP which has better thermal stability and strength than LCP under both IR reﬂ ow and

normal operating environments.

Reliability tests performed on inductors assembled with DAP mounting bases revealed that the

components’ mechanical structure remained unchanged. The implementation of the new mount-

ing base material does not affect either the inductors’ electrical characteristics or its mechanical

dimensions.
