145F

Overview

The Hammond Manufacturing 145F is a chassis-mount audio transformer designed for driver applications within the 143-146 series. It features a primary impedance of 600 ohms with a center tap and secondary impedances of 200 ohms with a center tap. The component supports a maximum DC current of 20 mA and has a maximum DC resistance of 45 Ohms. This unit serves as an audio transmission driver, facilitating signal coupling in electronic circuits requiring specific impedance matching.

Feature Summary

Chassis mount construction for secure installation
Audio transformer functionality optimized for driver stages
Center-tapped primary and secondary windings

Applications

Audio signal transmission driver circuits
Impedance matching in audio equipment
Electronic circuit coupling applications

Procurement Notes

Verify the exact datasheet specifications against the manufacturer's official documentation before procurement. Confirm that the 600 CT:200 CT configuration aligns with your circuit requirements. Ensure compatibility with chassis mounting standards and check for any recent revisions to the 143-146 series product line to guarantee correct part selection.

Selection Notes

Select this component when a 600 ohm center-tapped input is required to drive a 200 ohm center-tapped load in audio applications. Consider the 20 mA maximum DC current limit and 45 Ohm resistance constraints. Evaluate if the chassis mount form factor suits your enclosure design compared to PCB mount alternatives in the same series.

Part Context

Part of the Hammond Manufacturing 143-146 series, which includes various audio transformers. The 145F specifically addresses driver-side transformation needs. It complements other series components like the 145QBTBU or 1455J1201BK by providing the necessary signal conversion capabilities for complete audio system designs.

Replacement Considerations

Consult Hammond Manufacturing official cross-reference lists for verified substitutes. No public substitute part numbers are confirmed in available data.
