Overview
The Hammond Manufacturing 1140-LU-F is a single-channel audio signal transformer designed for line output applications. It features chassis mounting and utilizes a nickel alloy core to ensure high performance and wide bandwidth. The component operates within a frequency response range of 20 Hz to 20 kHz with a tolerance of ±0.35 dB. Electrical specifications include a primary impedance of 600 ohms and a secondary impedance configuration of 150/150 ohms, resulting in a 2:1 turns ratio. The physical dimensions are 3.25 inches in length, 1.55 inches in width, and 1.95 inches in height.
Feature Summary
- Utilizes nickel alloy cores for high performance and wide bandwidth capabilities
- Designed specifically for line output audio applications
- Supports chassis mounting for secure installation
Applications
- Audio line output interfacing
- Signal transformation in professional audio equipment
- Chassis-mounted audio circuit integration
Procurement Notes
Verify the specific impedance configuration required for your application, as datasheets may list variations such as 600-to-150 or 600-to-80 ohm ratios. Confirm that the chassis mount style and wire lead termination match your assembly requirements. Ensure the operating frequency range of 20 Hz to 20 kHz meets your system's audio fidelity standards before finalizing procurement.
Selection Notes
Select this model when a 2:1 impedance transformation ratio is necessary for line-level audio signals. The nickel alloy core provides superior frequency response compared to standard materials, making it suitable for high-fidelity applications. Consider the physical dimensions and chassis mounting requirements to ensure compatibility with your enclosure design and available space constraints.
Part Context
This component belongs to the 1140 series of audio transformers from Hammond Manufacturing. The series includes various models with different impedance ratios and configurations, such as the 1140-LU-B and 1140-LU-D. All units in this family share similar construction methods using nickel alloy cores and are intended for professional audio signal processing tasks requiring reliable impedance matching.
Replacement Considerations
The 1140-LU-B is a documented alternative within the same series, offering similar chassis-mount construction and nickel alloy core technology. Verify that the impedance ratio of the substitute matches the original design requirements to maintain proper signal transfer characteristics.
