T1/E1/CEPT/ISDN-PRI
INTERFACE MODULES
Four Transformer Modules for Dual SMT
T1/E1 Ports, Extended Temperature Range
EXTENDED TEMPERATURE RANGE MODELS
1. Extended Temperature Range Models — For extended temperature range transformers (-40°C to +85°C operating temperature range), OCL (Open Circuit Inductance)
2. Turns ratio is specified primary:secondary (CT = Center Tap).
3. Standard packaging for the surface mount package is anti-static tubes. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number,
