Overview
The Tamura TV105 is a telecommunications transformer designed for telephone applications. It features a primary impedance of 600 Ohms and an insertion loss of 1.15 dB. This component facilitates signal transmission in voice-grade circuits, ensuring proper impedance matching and isolation between line and equipment sides.
Feature Summary
- Designed for telephone circuit interfacing
- Provides 600 Ohm primary impedance matching
- Maintains low insertion loss for signal integrity
Applications
- Telephone line interface circuits
- Voice communication equipment
- Telecommunications terminal adapters
Procurement Notes
Verify the specific datasheet version (e.g., TV105-12D) to confirm exact mechanical dimensions and electrical tolerances. Ensure compliance with RoHS status requirements as some listings indicate non-compliance. Confirm package type and pin configuration against the target PCB layout before ordering.
Selection Notes
Select this component when a standard 600 Ohm telephone transformer is required for voice band applications. Consider the 1.15 dB insertion loss specification for link budget calculations. Verify environmental ratings if operating outside standard indoor conditions.
Part Context
The TV105 belongs to Tamura's audio and signal transformer portfolio, specifically targeting legacy and modern telephony infrastructure. It serves as a critical interface element between analog telephone lines and internal electronic circuitry, providing necessary galvanic isolation and impedance transformation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires consulting official Tamura replacement guides or authorized distributor substitution lists.
