101V

Overview

The Hammond Manufacturing 101V is a miniature audio transformer designed for push-pull tube output circuits. It features a rugged, potted construction suitable for printed circuit board (PCB) mount applications. The component operates with a 1:1 turns ratio and supports an input voltage of 100Vrms. Primary DC resistance is specified at 44 Ohms, while secondary DC resistance is 52 Ohms. It utilizes an 8-terminal configuration with PC pin through-hole termination style.

Feature Summary

• Designed specifically for general-purpose use and replacement in push-pull tube output circuits
• Features rugged, potted construction to ensure durability in PCB mount applications
• Provides a 1:1 turns ratio for signal coupling tasks

Applications

• Push-pull tube output circuits
• General-purpose audio signal coupling
• Replacement use in vintage or retro audio equipment

Procurement Notes

Verify the specific terminal pitch and mounting orientation against your PCB layout before ordering. Confirm that the 100Vrms rating aligns with your circuit's operational requirements. Ensure compatibility with through-hole assembly processes. Check for any regional shipping restrictions associated with electronic components from this manufacturer.

Selection Notes

Select the 101V when a 1:1 isolation transformer is required for tube-based audio stages. Consider its compact form factor for space-constrained designs. Evaluate the DC resistance values to ensure they match the impedance matching needs of your specific tube amplifier topology. Compare against other Hammond 101 series variants if different ratios are needed.

Part Context

This component belongs to the Hammond 101 Series of miniature audio transformers. The series is characterized by small footprints and robust potting materials intended for reliable performance in audio electronics. Hammond Manufacturing produces this line to serve both original equipment manufacturers and repair technicians in the audio industry.

Replacement Considerations

Direct substitutes within the same series may offer different impedance ratios. Verify that any replacement maintains the 1:1 ratio and compatible physical dimensions for PCB mounting. Ensure the replacement unit also meets the 100Vrms specification.
