149T

Overview

The Hammond Manufacturing 149T is an audio transformer designed for open-frame PC board mounting. It features a push-pull tube output configuration with a center-tapped primary and secondary winding. The impedance ratio is 600 CT to 600 CT ohms. The frequency range spans from 200 Hz to 15 kHz. Physical dimensions are 0.82 inches in height, 1.06 inches in length, and 0.82 inches in width. The component utilizes radial termination for through-hole installation.

Feature Summary

Designed for general-purpose use and replacement in push-pull tube output circuits
Features high-quality magnetics suitable for tube applications such as hi-fi systems
Economical open type construction with horizontal bracket design
Includes clinching lugs for extra mounting strength

Applications

Push-pull tube output circuits
Hi-fi audio systems
Signal level transformation
General-purpose audio applications

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact physical tolerances. Ensure the center-tapped configuration matches the target circuit requirements. Cross-reference the pinout diagram with the PCB layout to prevent installation errors. Confirm that the operating temperature range aligns with the environmental conditions of the final assembly.

Selection Notes

Select this model when a center-tapped 600-ohm to 600-ohm impedance match is required for tube-based audio outputs. Consider the open-frame design for applications where enclosure space allows for direct board mounting without shielding constraints. Evaluate the frequency response against the specific audio bandwidth needs of the application.

Part Context

The 149T belongs to the Hammond 149 series of audio transformers. This series is characterized by economical, open-type construction intended for horizontal bracket mounting. The components are engineered for reliability in audio signal transmission, specifically targeting vintage and modern tube amplifier designs requiring precise impedance matching.
