Inductors: Standard series of transformers for DSL splitters (TDK-EPC Corporation)
TDK-EPC, a group company of the TDK Corporation, presents a new standard series of splitter transformers from EPCOS for DSL applications. The series comprises 8 inductance values ranging from 1 to 10 mH.
Thanks to their dimensions of only 9.6 x 7.8 x 10.9 mm³, the new transformers with EP7 cores permit highly space-saving designs. In addition to good symmetry properties, the components are distinguished by very low signal distortions. Their low DC resistance, which is between 0.8 and 20 Ω depending on the type, ensures minimal losses. The transformers are RoHS-compatible.
In addition to the new standard series, TDK-EPC continues to supply customer-specific transformers with corresponding cores and inductance values. TDK-EPC also offers film capacitors used in the design of splitters.
- DSL: Digital Subscriber Line. DSL designates a series of standards for the high-speed transmission of data between the subscriber and the exchange via twisted copper pairs.
- Splitters: Systems comprising transformers and capacitors used to separate the telephone and DSL signals. Splitters are needed both at the subscriber access and the exchange.
- Splitters for separating DSL and telephone signals
Main features and benefits
- Low space requirement
- Good symmetry properties
- Low signal distortion
