Overview
The TY-146P-B is a printed circuit audio transformer from Triad Magnetics, designed for line matching and isolation applications. It operates within a frequency range of 200 Hz to 15,000 Hz. The device features a primary impedance of 600Ω center-tapped with a 150Ω section, and a secondary impedance of 600Ω center-tapped with a 150Ω section. It has a power rating of 100 mW (1/10 W). The primary resistance is 17 Ohms, and the secondary resistance is 22 Ohms. The unit utilizes a bobbin construction suitable for through-hole mounting.
Feature Summary

Procurement Notes
Verify that the specific suffix '-B' corresponds to the intended packaging or variant configuration as defined by Triad Magnetics. Confirm that the electrical specifications, particularly the 600Ω CT / 150Ω impedance ratio, align with the target circuit design requirements before finalizing procurement orders.
Selection Notes
Select this component when a 1:1 audio transformer with specific 600Ω and 150Ω impedance taps is required. Ensure the operating environment supports the specified frequency range of 200 Hz to 15,000 Hz. Verify that the 100 mW power rating is sufficient for the signal levels in the application.
Part Context
This part belongs to the Triad Magnetics audio transformer series, which includes various models like TY-311P and MET-46-T. These components are generally used for signal isolation and impedance transformation in audio and communication systems. The TY-146P-B specifically addresses applications requiring precise impedance matching between stages.
Replacement Considerations
Direct substitutes may include other Triad Magnetics audio transformers such as TY-307P or MET-31 if impedance and pinout compatibility can be verified. Cross-referencing datasheets for identical 600Ω CT / 150Ω specifications is necessary to ensure functional equivalence.
