PH9400.211NLT

Overview

The PH9400.211NLT is a surface-mount pulse transformer from Pulse Electronics, designed for high isolation applications. It features an inductance of 6.48 mH and supports a voltage-time product of 375 V·µs. The device provides 4 kV isolation between windings and utilizes a 2:1:1 turns ratio. Its physical dimensions are 16.70 mm in length, 12.70 mm in width, and a maximum height of 14.20 mm. The component operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides high electrical isolation suitable for safety-critical circuits
• Optimized for gate drive signal transmission in power electronics
• Designed for automated surface-mount assembly processes

Applications

• Battery Management Systems (BMS)
• Gate driver circuits for power switches
• Isolated communication interfaces in industrial equipment

Procurement Notes

Verify the specific suffix NLT against the manufacturer's current datasheet to confirm packaging and compliance status. Ensure the ordering quantity aligns with standard reel sizes defined by Pulse Electronics. Cross-reference the DigiKey part number 553-3358-2-ND for accurate distributor identification. Confirm that the 4kV isolation rating meets the system's safety requirements before finalizing the purchase order.

Selection Notes

Select this component when a 6.48 mH inductance and 2:1:1 turns ratio are required for isolated gate driving. The 4 kV isolation rating distinguishes it from lower-voltage variants in the PH9400 series. Consider the 14.20 mm height constraint for PCB layout clearance. Verify thermal performance at the maximum operating temperature of +125°C for the intended application environment.

Part Context

This component belongs to the PH9400 series of high-isolation SMT transformers from Pulse Electronics. The series is specifically engineered for Battery Management Systems and other applications requiring reinforced or basic insulation barriers. It shares common form factors with related models like the PH9400.111NLT but differs in inductance and voltage-time specifications.

Replacement Considerations

Direct substitutes within the same series include PH9400.111NLT and PH9400.122NLT, though these have different inductance values (4.5 mH and 2.88 mH respectively). Verify that the alternative inductance does not disrupt the timing characteristics of the gate drive circuit.
