PH9384.089NLT

Overview

The PH9384.089NLT is a surface-mount isolation transformer from Pulse Electronics, designed for push-pull converter applications. It features a patented Sidecar structure with a compact footprint of 12.5 mm length, 9.2 mm width, and 7.6 mm height. The component provides 4000 Vrms isolation voltage and a 9.5 mm creepage distance. Electrical specifications include a power rating of 3 W, an inductance of 538 µH, and a winding configuration of 8CT:9CT. It supports dual primary and dual secondary windings.

Feature Summary

• Patented Sidecar structural design enabling compact surface-mount integration
• Enhanced insulation providing high isolation barrier safety
• Optimized for low-power transmission across isolation barriers
• Compatible with multiple integrated circuit gate drivers

Applications

• Industrial communication bus interfaces such as RS485, ModBus, and ProfiBus
• Systems requiring protection against large ground loops and electrical noise
• Industrial control and building automation systems
• Smart grid and monitoring equipment applications

Procurement Notes

Verify the specific suffix NLT to confirm tape-and-reel packaging configuration. Ensure compatibility with reflow soldering profiles specified in official documentation. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Cross-reference manufacturer part numbers with distributor catalogs to avoid ordering errors based on similar series variants.

Selection Notes

Select this component when space constraints require a low-profile isolation solution with high voltage ratings. The 3 W power rating suits low-power interface needs. Consider the 8CT:9CT winding ratio for specific driver requirements. Evaluate thermal performance within the -40°C to +125°C operating range. Compare physical dimensions against board layout restrictions before finalizing the design.

Part Context

This part belongs to the PH9384 series of toroidal isolation power transformers by Pulse Electronics, a YAGEO Company. The series utilizes a unique SMD platform architecture distinct from traditional bulky isolation transformers. It addresses the need for compact, cost-effective industrial designs while maintaining robust electrical isolation standards for sensitive communication interfaces.

Replacement Considerations

Consult official substitution lists for direct equivalents. Verify pinout and electrical parameters match exactly. Check mechanical footprint compatibility if substituting with other series members.
