104Q

Overview

The Hammond Manufacturing 104Q is a miniature audio transformer designed for printed circuit board mounting. It features an epoxy potted construction to secure internal components and protect against environmental factors. The unit utilizes a square pin type configuration, with pins typically measuring 0.025 inches in size, facilitating direct integration into PCB layouts. This component belongs to the 104 Series, which offers various output power models ranging from 5 to 1,500 milliwatts. The specific 104Q model provides a primary impedance of 500 ohms with a center tap and a secondary impedance of 3.2 ohms, suitable for low-power audio signal applications.

Feature Summary

• Epoxy potted construction for mechanical stability and environmental protection
• Square pin type design optimized for printed circuit board mounting
• Center-tapped primary winding configuration for balanced audio signals
• Miniature form factor within the 104 Series product line

Applications

• Low-power audio signal coupling in electronic circuits
