Overview
The Hammond Manufacturing 141F is an audio signal transformer designed for through-hole PC board mounting. It features a center-tapped primary winding with an impedance of 25,000 ohms and two center-tapped secondary windings, each with an impedance of 50 ohms. The component operates within a frequency range of 20 Hz to 20 kHz. Electrical specifications include a primary DC resistance of 375 ohms and a secondary DC resistance of 0.8 ohms per winding. The unit has a power rating of 10 mW and measures 0.78 inches in length, 0.66 inches in width, and 0.46 inches in height.
Feature Summary
- Center-tapped dual secondary winding configuration for balanced audio applications
- Low-profile radial leaded construction suitable for printed circuit board integration
- Designed for high-fidelity audio signal coupling and impedance matching
Applications
- Audio amplifier input stages
- Impedance matching between microphone sources and preamplifiers
- Balanced line driving circuits
Procurement Notes
Verify the specific manufacturer part number against official Hammond Manufacturing documentation to confirm electrical parameters and physical dimensions. Ensure that the required center-tapped configuration matches the design schematic. Cross-reference datasheet revisions to confirm compliance with current RoHS directives and material composition standards before finalizing procurement orders.
Selection Notes
Select this component when a low-profile audio transformer with dual center-tapped secondaries is required for PCB assembly. Consider the 25k:50CT impedance ratio for appropriate source and load matching. Evaluate the 10 mW power handling capability against the expected signal levels in the target circuit to ensure reliable operation without saturation or distortion.
Part Context
The 141F belongs to the Hammond Manufacturing 141 series of audio transformers. This series provides various impedance ratios and winding configurations for professional audio equipment. The 141F specifically addresses applications requiring balanced output from high-impedance sources, distinguishing it from single-secondary variants within the same product family.
