- Designed specifically for impedance matching and line balancing in telecommunication systems.
- Features radial pin terminals for reliable through-hole mounting on printed circuit boards.
Applications
- Voice and data coupling in telecommunications equipment
- Impedance matching between audio stages
- Line balancing and bridging applications
Procurement Notes
Verify the specific part number suffix against manufacturer documentation to confirm package quantity requirements. The 'B' suffix indicates a factory-defined packaging configuration rather than a functional change. Ensure that the procurement channel provides original manufacturer documentation to validate component authenticity and compliance with RoHS standards before finalizing orders.
Selection Notes
Select this component when a 600 Ohm center-tapped to 600 Ohm center-tapped audio transformer is required for voice band applications. Consider the 90 mA DC current rating and the 300 Hz to 3.5 kHz frequency response to ensure compatibility with the system's signal characteristics. Verify that the through-hole mounting style and physical dimensions fit the available PCB space and assembly constraints.
Part Context
The TY-401P-B belongs to the TY series of audio transformers manufactured by Triad Magnetics. This series is engineered for various industrial and communication uses, including repeat coils and hybrid circuits. The component utilizes an unshielded design suitable for environments where external magnetic interference is minimal or managed through layout techniques.
Replacement Considerations
