125H

Overview

The Hammond Manufacturing 125H is an audio transformer designed for universal push-pull tube output applications. It features a single channel configuration with terminal end connections and operates within a frequency range of 150 Hz to 15 kHz. The unit has a power rating of 3 watts, a primary coil impedance of 25 kOhms, and a secondary coil impedance of 15 Ohms. The inductance is specified at 14.94 H. Physically, the unshielded component measures 2.06 inches in length, 1.25 inches in width, and 1.19 inches in height, weighing approximately 394.6 grams.

Feature Summary

Designed specifically for universal push-pull tube output configurations
Provides signal transformation between high-impedance primary and low-impedance secondary circuits
Constructed with terminal connections for direct circuit integration

Applications

Tube amplifier output stages
Audio signal processing equipment
Push-pull circuit implementations

Procurement Notes

Verify the specific datasheet version for the 125H model to confirm exact electrical tolerances and physical dimensions prior to integration. Ensure compatibility with the target tube amplifier's impedance requirements. Confirm that the terminal connection type matches the existing wiring infrastructure. Check for any regional shipping restrictions or compliance certifications required for the destination market.

Selection Notes

Select this component when a dedicated audio transformer for push-pull tube outputs is required. The 25 kOhm primary and 15 Ohm secondary impedances define its specific application niche. Consider the physical dimensions and unshielded design when planning enclosure space and electromagnetic interference mitigation strategies relative to other circuit components.

Part Context

The 125H belongs to the Hammond Manufacturing series of audio and signal transformers. These components are engineered for specialized audio electronics, particularly vintage or high-fidelity tube-based amplification systems. The product line emphasizes robust construction suitable for continuous operation in professional audio environments.
