PH9385.015NLT

Overview

The PH9385.015NLT is a specialty transformer manufactured by Pulse Electronics, designed for RS-485 communication applications. It features a push-pull configuration with an inductance of 1.35 mH and a turns ratio of 1:5. The component provides 4 kV isolation voltage and supports a maximum voltage utilization of 70 Vus. It is housed in a surface-mount package with a maximum height of 7.50 mm (0.295 inches). The device complies with RoHS3 standards and carries an MSL rating of 1.

Feature Summary

• Engineered specifically for RS-485 bus line transceiver circuits
• Provides high-voltage isolation capability for signal integrity
• Optimized push-pull topology for differential signaling

Applications

• RS-485 communication interface design
• Industrial automation control systems
• Building automation networks

Procurement Notes

Verify the specific suffix NLT to confirm tape-and-reel packaging compatibility with automated assembly equipment. Confirm that the 1.35 mH inductance value aligns with the target network impedance requirements. Ensure the 4 kV isolation rating meets the safety standards of the end application environment. Cross-reference the footprint dimensions against the PCB layout to guarantee mechanical fit within the enclosure constraints.

Selection Notes

Select this component when designing robust RS-485 interfaces requiring galvanic isolation between nodes. The 1:5 turns ratio suits specific driver configurations found in industrial protocols. Consider the 7.50 mm profile if vertical clearance is limited on the assembly board. This part is suitable for environments demanding compliance with RoHS3 regulations without compromising electrical performance or isolation reliability.

Part Context

This component belongs to the PH9385 series of specialty transformers from Pulse Electronics. The series focuses on providing reliable isolation for serial communication buses. Unlike general-purpose magnetics, these units are tuned for the specific frequency and impedance characteristics required by standard industrial data transmission protocols.
