LM-NP/-LP 1000 Series - Line Matching Transformers
*RoHS Directive 2002/95/EC Jan 27, 2003 including Annex.
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications
Note
The LM-NP/-LP-1000 Series Line
Matching Transformers meet the return
loss specifi cations of BS 6305.
It is important, however, to use the
circuit recommended by BS 6305 for
return loss measurements.
The LM-NP-1000 Series are EN 41003
approved.

* Due to the unique design and the most advanced manufacturing techniques the 2 coils are fully identical, meaning there is no real
primary nor secondary winding. Depending on the application, the transformers can be used either way.
