140K

Overview

The Hammond Manufacturing 140K is an obsolete audio and signal transformer designed for voice coil applications. It features a frequency range of 70 Hz to 11 kHz with screw end termination. The primary impedance is 4 Ohms, while the secondary impedance is 60 kOhms. This unshielded unit measures 1 inch in height and weighs 59 grams. It is classified under the 140 series and utilizes a signal level application type.

Feature Summary

• Designed for voice coil audio and signal transformer applications
• Features screw end termination for secure connection
• Operates within a frequency range of 70 Hz to 11 kHz

Applications

• Voice coil interfacing
• Signal level transformation
• Audio equipment integration

Procurement Notes

Verify component status as the 140K is marked obsolete. Confirm availability through remaining new original inventory sources. Check shipping restrictions due to weight or size limitations which may require specific currency or country constraints. Ensure compatibility with existing circuit requirements before procurement.

Selection Notes

Select this component only if legacy support for the 140 series is required. Verify that the 4 Ohm primary and 60 kOhm secondary impedances match the system design. Consider the unshielded nature for potential interference issues. Evaluate alternative models from the same manufacturer if current stock is insufficient.

Part Context

The 140K belongs to the Hammond Manufacturing 140 series of audio transformers. This series is known for robust construction suitable for industrial and professional audio environments. As an obsolete part, it represents older design standards compared to current offerings in the company's audio and signal transformer portfolio.

Replacement Considerations

No public confirmed substitute part numbers are available for the 140K. Users must evaluate functional equivalents based on impedance and frequency specifications. Consult Hammond Manufacturing for current product line recommendations.
