PH9085.034NLT

Overview

The PH9085.034NLT is a surface-mount isolation transformer manufactured by Pulse Electronics, designed for high-isolation applications. It features an inductance of 1.02 mH and provides 2.5 kV isolation voltage. The component utilizes a 3:4 turns ratio with three primary and four secondary coils. Its physical dimensions are 8.10 mm in length, 7.10 mm in width, and a maximum height of 5.08 mm. The device is RoHS3 compliant and classified under MSL Level 1.

Feature Summary

• Provides 2.5 kV electrical isolation between windings
• Surface mount construction for automated assembly
• Optimized for MAX253 compatible circuits

Applications

• MAX253 power management circuits
• High isolation signal coupling
• SMT board-level power transformers

Procurement Notes

Verify the specific suffix 'NLT' to confirm surface-mount tape-and-reel packaging compatibility. Ensure the procurement source references the official datasheet for the PH9085 series to validate the 1.02 mH inductance and 2.5 kV isolation ratings. Confirm RoHS3 compliance status matches current regulatory requirements before finalizing orders.

Selection Notes

Select this component when a compact SMT footprint is required alongside high isolation voltage. The 3:4 turns ratio suits specific impedance matching needs within the PH9085 family. Consider the 5.08 mm maximum height constraint for strict vertical clearance limitations on the target PCB layout.

Part Context

This part belongs to the PH9085 series of specialty isolation transformers from Pulse Electronics. The series focuses on providing robust galvanic isolation in small surface-mount packages. It serves as a specialized solution for power conversion and signal integrity in dense electronic assemblies requiring verified isolation barriers.
