Technical content

TLA 2276 is designed to be used in a 2-coil hybrid transformer configuration with the following features:

  • Low Insertion Loss.
  • High Return loss.
  • DC capability.
  • High Transhybrid Loss. Applications: Hybrid Interface between the 2- wire loop and the 4-wire circuit, and where DC handling capabil- ity is required on the 2-wire side. Audio Hybrid Transformer TLA 2276 TLA 2276 has the following electrical performance in a 2-coil hybrid configuration, as per diagram, when ter- minated with specified impedances and with up to 70 mA loop current at the 2-wire port.
