LM-LP-1003L

Overview

The Bourns LM-LP-1003L is a line matching transformer from the LM-NP/-LP 1000 Series, designed for audio signal applications. It features a 1:1 turns ratio and utilizes PC pin through-hole mounting. The component includes six terminals and provides high isolation with a dielectric strength of 6500VDC. Primary and secondary DC resistances are both specified at 90 Ohms. The unit has an inductance of 2.8 H and a maximum seated height of 0.496 inches (12.60mm).

Feature Summary

• Provides electrical isolation between audio circuits via a 1:1 line matching design.
• Features high voltage insulation capability rated at 6500VDC for safety.
• Constructed with a six-terminal configuration for flexible circuit integration.

Applications

• Audio equipment signal interfacing
• Line matching in professional audio systems
• Balanced to unbalanced signal conversion

Procurement Notes

Verify the specific datasheet version when ordering, as specifications are subject to change without notice. Confirm that the 'L' suffix aligns with the required package or specification variant for your design. Ensure compatibility with through-hole assembly processes given the PC pin mounting type. Cross-reference the 90 Ohm resistance values against your circuit requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring balanced audio signal transmission with high isolation needs. The 1:1 ratio makes it suitable for direct line matching where impedance transformation is not required. Consider the 6500VDC rating for environments demanding robust electrical separation. The through-hole format is appropriate for standard PCB manufacturing workflows.
