PH9384.035NL

Overview

The PH9384.035NL is a toroidal isolation power transformer from Pulse Electronics, designed for surface mount applications. It features a patented Sidecar structure providing enhanced insulation with a 4 kV RMS isolation voltage and a 9.5 mm creepage distance. The component operates within a temperature range of -40°C to 125°C and utilizes a six-terminal gull-wing SMD package. It complies with UL60950-1 2nd edition standards and RoHS directives.

Feature Summary

• Patented Sidecar structure for compact surface mount integration
• High isolation capability with 4 kV RMS voltage rating
• Enhanced insulation safety with 9.5 mm creepage distance
• Compatible with multiple IC driver architectures

Applications

• Industrial communication bus interfaces such as RS485, ModBus, and ProfiBus
• Systems requiring protection against large ground loops and electrical noise
• Isolated power supply gate driving in industrial control environments

Procurement Notes

Verify the specific suffix configuration when ordering, as variations exist between NL and NLT designations regarding packaging and compliance certifications. Confirm that the selected variant matches the required thermal operating range and mechanical footprint specifications for the target PCB layout. Ensure compatibility with the intended driver circuit topology before finalizing procurement.

Selection Notes

Select this component for designs demanding high isolation in space-constrained industrial settings. The toroidal geometry supports efficient magnetic coupling while maintaining a low profile suitable for automated assembly. Consider the 4 kV RMS rating when designing for environments with significant potential differences or noise interference between isolated sections.

Part Context

This part belongs to the PH9384 series of push-pull converter transformers. The series is characterized by its ability to provide small power across an isolation barrier using a flat, compact SMD form factor. It addresses the limitations of traditional bulky isolation transformers in modern electronic systems requiring robust safety margins.

Replacement Considerations

Direct substitutes are not explicitly documented in the provided source material. When evaluating alternatives, ensure the replacement maintains the 4 kV RMS isolation rating, 9.5 mm creepage distance, and compatible SMD terminal configuration to preserve system safety and mechanical integrity.
