• Utilizes a compact surface-mount toroidal platform for space efficiency
• Features reinforced insulation standards for enhanced safety

Applications

• Industrial control systems
• Building automation interfaces
• Smart grid monitoring equipment

Procurement Notes

Verify the specific suffix requirements against the manufacturer's current datasheet to ensure compliance with RoHS directives and packaging specifications. Confirm that the 4CT:3CT turns ratio aligns with the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a compact, high-isolation solution is required for low-power transmission across barriers. Ensure the PCB layout accommodates the specified 12.50mm by 9.20mm footprint and 7.60mm maximum height constraints.

Part Context

This part belongs to the PH9384 family of pulse transformers engineered for industrial communication bus interfaces such as RS485 and ModBus. These devices address grounding loop issues and electrical noise in distributed systems where traditional transformers may be too large.

Replacement Considerations

Cross-reference with other PH9384 variants like PH9384.034NL or PH9384.083NL if different turns ratios are acceptable. Verify mechanical compatibility and electrical specifications against official substitution lists.
