107N

Overview

The Hammond Manufacturing 107N is a miniature epoxy-potted audio transformer designed for printed circuit board mounting. It features a primary impedance of 10,000 ohms with center tap and a secondary impedance of 600 ohms with center tap. The unit operates within a frequency range of 300Hz to 50kHz with a response tolerance of ±1.5dB. Electrical specifications include a primary DC resistance of 240 ohms and a secondary DC resistance of 8.5 ohms. The isolation voltage is rated at 100VRMS, and the power handling capacity is 150mW. Physical dimensions are 0.630 inches in length, 0.586 inches in width, and 0.630 inches in maximum height.

Feature Summary

• Miniature epoxy potting provides mechanical stability and environmental protection
• Center-tapped windings on both primary and secondary sides facilitate balanced circuit integration
• Printed circuit board mount style ensures secure surface attachment

Applications

• Audio signal transmission systems
• Impedance matching between stages
• Balanced line interfacing

Procurement Notes

Verify the specific part number against official Hammond Manufacturing documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with intended PCB layout and thermal requirements. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a compact audio transformer with specific 10k-to-600 ohm impedance transformation is required. Consider the center-tap configuration for balanced applications. Evaluate the frequency response characteristics against system bandwidth needs. Verify that the power rating meets operational signal levels without saturation.

Part Context

This component belongs to the 107 series of audio transformers manufactured by Hammond Manufacturing. The series includes variants with different impedance ratios, such as the 107H model which utilizes a 600CT-to-600CT configuration. These units are generally characterized by their small form factor and robust epoxy construction suitable for industrial electronics.

Replacement Considerations

Cross-reference with other Hammond 107 series models like the 107H if impedance ratios differ from project requirements. Verify pinout compatibility and mounting hole spacing when substituting with equivalent components from other manufacturers.
