LM-LP-1005L

Overview

The LM-LP-1005L is a line matching transformer from Bourns Inc.'s LM-NP/-LP 1000 Series. It features a 1:1 turns ratio and provides galvanic isolation with a 6500VDC dielectric strength. The primary winding has a DC resistance of 90 Ohms, while the secondary winding also exhibits a 90 Ohm DC resistance. This component is designed for audio signal transmission applications requiring balanced line interfacing.

Feature Summary

• Provides galvanic isolation between audio circuits to reduce ground loop noise
• Features a 1:1 turns ratio for direct signal transfer without gain alteration
• Supports high voltage isolation up to 6500VDC for enhanced safety

Applications

• Audio line matching in professional sound systems
• Balanced-to-balanced signal interfacing
• Ground loop noise reduction in audio equipment

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing standards may evolve. Confirm that the 90 Ohm DC resistance values align with your circuit impedance requirements. Ensure the 6500VDC isolation rating meets the safety standards of the target application environment. Cross-reference the package type and pin configuration with the official mechanical drawings before integration.

Selection Notes

Select this component when a 1:1 transformation ratio is required for balanced audio lines. The 90 Ohm winding resistance suits moderate impedance sources and loads. Consider the physical size and mounting style if space constraints exist within the chassis design. Evaluate thermal performance if operating in enclosed environments with limited airflow.
