2 Magnetic omponents for //EPT/ISDN-PRI - T/E/D/STS- TLEM PROILE ounded in, The TLEM International Group has established itself as a world leader in the manufacture of toroidal transformers and related magnetic components. Our strong technical engineering expertise has contributed to the growth of our current workforce to over, employees in manufacturing locations in Ireland, the zech Republic and India. Over the years The Talema Group has succeeded in designing, producing and delivering in excess of million transformers to its customers. The recent incorporation of xdsl technology into our extensive range of Telecom and LN magnetics offerings, such as ISDN, ase-t, Ethernet transformers for /ase-t, has broadened our market offering to an even higher level. QULITY The TLEM Group has a total commitment to quality. ll facilities maintain very stringent Quality ontrol and Quality ssurance procedurees and are certified to and manufacture in accordance with ISO- and meet a broad range of International Standards including UL, VDE, IE, and EN. Performance has been proven in the many design in s of our products. The fact that we maintain a ship-to-stock vendor rating with over national and international companies is, to us, the best testimonial of our commitment to quality.

Performance has been proven in the many design-ins of our products in these applications. Quality and consistency is guaranteed through % testing of the specified parameters for Primary Inductance, Leakage Inductance, Turns Ratio, D resistance and Interwinding apacitance. This ensures that the Return Loss and Pulse Waveshape requirements of ITU-T G. and NSI can be met. dditionally all parts are % tested for V minimum isolation. Temperature Performance Products are offered for both standard temperature (ommercial to ) and extended temperature (Industrial - to ) applications. Required minimum inductance levels are maintained at the lower temperature limits. dvanced design means that the MJM series may be used for either temperature classification.
