Overview
The Hammond Manufacturing 1140-LU-G is a single-channel audio and signal transformer designed for line output applications. It features chassis mounting with wire lead termination. The core material is nickel alloy. Primary impedance is 680 ohms with a resistance of 40 ohms. Secondary impedance is 80 ohms with a resistance of 40 ohms. The frequency response ranges from 20Hz to 20kHz. Physical dimensions are 3.25 inches in length, 1.55 inches in width, and 1.95 inches in height.
Feature Summary
- Chassis mount construction for stable installation
- Nickel alloy core material for signal integrity
- Wire lead termination for circuit integration
Applications
- High performance tube line output stages
- Studio grade impedance matching
- Audio signal transformation
Procurement Notes
Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct impedance configuration and termination type. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference primary and secondary impedance values with system requirements before procurement to prevent mismatch issues.
Selection Notes
Select this component when a single-channel audio transformer with specific 680-ohm primary and 80-ohm secondary impedances is required. Consider the chassis mount form factor and wire lead termination for compatibility with existing enclosure designs and wiring harnesses. Evaluate the nickel alloy core properties for intended frequency range performance.
Part Context
This component belongs to the 1140 series of studio grade impedance matching transformers manufactured by Hammond Manufacturing. The series includes variants such as 1140-LU-A, 1140-LU-D, and 1140-LU-E, which share similar chassis mount characteristics but may differ in impedance ratios or specific application tuning.
Replacement Considerations
Direct substitutes within the same series include models like 1140-LU-A, 1140-LU-D, and 1140-LU-E. Verify that alternative part numbers match the required primary and secondary impedance values and physical mounting dimensions before substitution.
