PH9085.083NLT

Overview

The PH9085.083NLT is a surface-mount isolation transformer from Pulse Electronics, designed for high-isolation applications. It features an inductance of 1.16 mH and provides 2.5 kVrms isolation voltage. The component utilizes an 8CT:3CT winding configuration with six terminals in a gull-wing SMD package. Its physical dimensions are 8.10 mm in length, 7.10 mm in width, and a maximum height of 5.08 mm. It operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides 2.5 kVrms electrical isolation between windings for signal integrity.
• Optimized for RS-485 and RS-232 communication interface protection.
• Utilizes a compact surface-mount gull-wing package for automated assembly.

Applications

• RS-485 communication bus isolation
• RS-232 serial port isolation
• Industrial control system signal interfaces

Procurement Notes

Verify the specific suffix NLT against the manufacturer's current datasheet to confirm packaging type and compliance status. Ensure the ordering quantity meets the minimum order increment requirements specified by authorized distributors. Cross-reference the component marking with the official part number to prevent counterfeit substitution during receipt inspection.

Selection Notes

Select this component when high isolation voltage is required for serial communication lines. The 1.16 mH inductance supports standard baud rates for RS-485/RS-232 protocols. Consider the 8.10 x 7.10 mm footprint for PCB layout constraints. Verify thermal management capabilities given the 125°C maximum operating temperature limit.

Part Context

This part belongs to the PH9085 series of high-isolation transformers from Pulse Electronics Power. The series is specifically engineered for digital communication interfaces requiring galvanic isolation. It complements other variants in the family that differ in inductance or winding ratios but share similar isolation characteristics and mounting styles.

Replacement Considerations

Direct substitutes include other PH9085 series variants such as PH9085.021NLT or PH9085.043NLT, provided the winding ratio and inductance values match the circuit design requirements. Verify pin compatibility and isolation voltage ratings before substitution.
