Pulse Transformers Applications

• Analog Devices quad isolation systems
• Digital isolation interfaces
• Data communication circuits requiring high isolation

Pulse Transformers Procurement Notes

Verify the specific suffix 'LTR' corresponds to the tape-and-reel packaging configuration rather than tube packaging when sourcing. Confirm that the 1.5 kV isolation rating meets the safety requirements of the target application circuit. Ensure the gull-wing footprint matches the PCB design constraints. Check RoHS compliance status through official manufacturer documentation prior to integration.

Pulse Transformers Selection Notes

Select this component when a 1:3 turns ratio and 389 uH inductance are required for isolated data lines. The 1.5 kV isolation voltage is suitable for standard industrial isolation barriers. Consider the 9.65 x 8.89 mm footprint for space-constrained designs. Verify thermal performance at maximum operating temperatures of +85 C during system design.
