Overview
The Hammond Manufacturing 1140-LU-A is a single-channel audio transformer designed for line output applications. It features chassis mounting with wire lead termination and utilizes a nickel alloy core material. The device provides an impedance ratio of 10,000 ohms to 600 ohms. Primary coil specifications include an impedance of 11.5 kohms and a resistance of 610 ohms. Secondary coil parameters are defined by an impedance of 100 ohms and a resistance of 45 ohms. Physical dimensions are 2.809 inches in length, 1.69 inches in width, and 1.653 inches in height.
Feature Summary
- Chassis mount construction for secure installation
- Nickel alloy core material for signal integrity
- Wire lead termination for circuit integration
Applications
- Line output signal transformation
- Audio equipment interconnection
- Impedance matching between circuits
Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct impedance ratios and physical configurations. Confirm that the wire lead termination style matches the target assembly requirements. Cross-reference the nickel alloy core specification if magnetic shielding properties are critical for the intended application environment.
Selection Notes
Select this component when a fixed 10k to 600 ohm impedance transformation is required for line-level audio signals. Consider the chassis mount form factor and wire lead availability during design. Evaluate the physical envelope constraints against the specified length, width, and height measurements to ensure proper fit within the enclosure.
Part Context
This unit belongs to the 1140 series of audio transformers manufactured by Hammond Manufacturing. The series includes variants such as the 1140-DB-A for direct box applications. These components are categorized under audio and signal transformers, distinct from industrial power or high-voltage plate transformers offered by the same manufacturer.
Replacement Considerations
The 1140-LU-F is a related variant within the same series but features a different impedance ratio of 600 to 150 ohms. Verify that the specific electrical transformation requirements align with the 10k to 600 ohm specification before substituting.
