106Q

Overview

The Hammond Manufacturing 106Q is a miniature epoxy-encapsulated audio transformer designed for push-pull tube output circuits. It features a primary impedance of 48CT ohms and a secondary impedance of 3.2 ohms. The device operates with a frequency range starting at 170Hz and supports a power level of 1.5W. Electrical characteristics include a primary DC resistance of 2.4 ohms and a secondary DC resistance of 300 milliohms. It provides 200V isolation and exhibits an insertion loss of 1dB. The component utilizes through-hole PC pin termination and measures 1.080 inches in length, 0.880 inches in width, and 0.950 inches in maximum height.

Feature Summary

• Miniature epoxy encapsulation for compact integration
• Designed specifically for push-pull tube output applications
• Through-hole mounting with PC pin termination

Applications

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

Procurement Notes

Verify the specific part number against official Hammond Manufacturing documentation to ensure compatibility with existing circuit designs. Confirm that the 48CT primary and 3.2 ohm secondary impedances match the target application requirements. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure that the physical dimensions fit within the designated enclosure space before finalizing procurement decisions.

Selection Notes

Select this component when a miniature audio transformer is required for tube-based push-pull amplifier stages. The 48CT primary impedance is suitable for specific tube plate-to-plate load requirements. Consider the 1.5W power handling capacity and 170Hz lower frequency limit when evaluating performance needs. The epoxy potting provides mechanical stability and protection against environmental factors during operation.

Part Context

The 106Q belongs to the Hammond 106 series of miniature audio transformers. This series is characterized by small form factors and epoxy encapsulation, making them suitable for space-constrained audio applications. The product is currently active and available for order from authorized distributors.

Replacement Considerations

Cross-reference with other Hammond 106 series variants such as the 106E for different impedance configurations. Verify that substitute components maintain identical primary and secondary impedance values to preserve circuit performance.
