CEPT/T1 TEW5721 Input/Output Transformer TEW5721 is designed to be used as an Input Transformer in the ISDN primary rate access network with the following devices: DS2187 - Dallas T 7290 - AT&T - PMC/Sierra PM4341 T1X & PM6341 E1 TEW5721-3 is designed to be used as an Input and Output Transformer for: - Siemens PEB2254 TEW5721-4 is designed for: - PMC-Sierra PM4351 TEW5721-5 is designed to be used as input transformer requiring turns ratios 1 : 2 or 1 : 1 TEW5721-1 is designed to be used as an Output Transformer for: - Brooktree BT8069B LXT310,318,360 - Level One MT9075 - Mitel Features TEW5721-6 is designed to be used as input transformer requiring turns ratios 1 : 3 Part numbering note: For SMD version: a) Filtran parts are now identified WITHOUT the "TEW" prefix. Add letter 'S' after part number. Therefore Filtran 5721 = TEW5721. E.g. TEW5721S-4.TDM Multiplexers. b) RoHS compliant parts may be ordered by adding a "-NL" suffix (for example, 5721-2-NL, 5721S-NL). Please check with Filtran customer service for availability. c) SMD parts are ordered with as "5721S-x", where x is the dash number. TEW5721-2 is designed to be used as an Input Transformer for: - Brooktree BT8069B LXT310, 318, 360 - Level One DS2151Q, DS2153Q - Dallas MT9075 - Mitel MECHANICAL Low cost. Through Hole and SMD.
