109N

Overview

The Hammond Manufacturing 109N is a potted audio and signal transformer designed for through-hole mounting. It features a primary impedance of 10k ohms and a secondary impedance of 600 ohms, providing a turns ratio of 4.08:1. The device operates within a frequency range of 300 Hz to 50 kHz and supports a power rating of 2W. Electrical characteristics include a primary DC resistance of 700 ohms and a secondary DC resistance of 60 ohms. The component utilizes pin terminals for circuit integration.

Feature Summary

Potted construction for environmental protection
Single-channel audio signal transformation
Through-hole pin terminal mounting interface

Applications

Audio line interstage coupling
Signal impedance matching in audio circuits
Line-level signal transformation

Procurement Notes

Verify the specific impedance configuration against project requirements, as variations exist between 1.5k CT and 600 ohm secondary options. Confirm that the 10k primary impedance aligns with the source circuit design. Ensure the through-hole package dimensions fit the PCB layout constraints. Cross-reference the manufacturer datasheet to validate the exact electrical parameters for the 109N suffix before finalizing the bill of materials.

Selection Notes

Select this component when a fixed 10k to 600 ohm impedance transformation is required for audio applications. Consider the 300 Hz to 50 kHz bandwidth limitations for high-fidelity or wideband signal processing needs. Evaluate the physical size and through-hole mounting style against available PCB real estate. Compare against other series transformers if different impedance ratios or surface-mount packages are necessary for the specific design topology.

Part Context

The 109N belongs to the Hammond 109 series of audio and signal transformers. This series is characterized by potted designs suitable for robust electronic environments. The product falls under the broader category of audio transformers manufactured by Hammond Manufacturing, distinct from their enclosure and wireway product lines.
