| Ro VER LEA H S SI D F CO ON RE M SA E PL R IA E NT Features Fully encapsulated LM -N P10 01 -B 1 Lead free version available (see How to Low profile High dielectric strength Ten models available Ex stock Competitively priced Order) Lead free versions are RoHS compliant* Applications Line matching Fax modem LM-NP/-LP 1000 Series - Line Matching Transformers Product Dimensions WHITE MARK 4321 2.5 (.100) Note: The LM-NP/-LP-1000 Series Line Matching Transformers meet the return loss specifications 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.
