1140-LN-E

Overview

The Hammond Manufacturing 1140-LN-E is a single-channel audio signal transformer designed for line input applications. It features chassis mounting and utilizes wire lead termination. The core material is a nickel alloy, providing shielding to minimize interference. Primary impedance is 800 ohms with a resistance of 27 ohms; secondary impedance is 800 ohms with a resistance of 74 ohms. The unit supports an impedance ratio of 600 to 600 and operates within a frequency range of 20Hz to 20kHz. Physical dimensions are 2.5 inches in length and 1.956 inches in width.

Feature Summary

Designed for high input levels up to +19dBu
Provides wide bandwidth and low distortion performance
Shielded construction using nickel alloy core material

Applications

Audio line input circuits
Chassis-mounted audio equipment integration
Signal transformation in professional audio systems

Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct impedance and termination specifications. Confirm that the nickel alloy core and shielding requirements align with the target application's electromagnetic interference constraints. Cross-reference datasheet parameters for primary and secondary resistance values prior to procurement to guarantee circuit compatibility.

Selection Notes

Select this component when a dedicated line input transformer with 600-to-600 ohm impedance matching is required. Ensure the chassis mount form factor fits the enclosure design. Consider the physical dimensions of 2.5 by 1.956 inches for spatial planning. Verify that the wire lead termination method suits the existing wiring infrastructure and that the operating frequency range covers the necessary audio spectrum.

Part Context

This component belongs to the Hammond Manufacturing 1140 series of audio and signal transformers. The series includes various configurations for line input and output applications. The 1140-LN-E specifically addresses line input needs with a balanced impedance configuration. Other variants in the series may offer different impedance ratios or termination styles, such as the 1140-LU-E for line output.
