PA0264NLT

Overview

The PA0264NLT is a surface mount pulse transformer manufactured by Pulse Electronics. It features a 1:1:1 turns ratio and an inductance of 1.14 mH. The component supports an ET value of 17.2 Vµs and operates within a temperature range of -40°C to +130°C. Its physical dimensions are 8.64 mm in length, 6.73 mm in width, and a maximum height of 3.56 mm. The device meets AEC-Q200 qualification standards for automotive applications.

Feature Summary

• Provides galvanic isolation with a 1:1:1 signal transformation ratio
• Qualified for automotive environments under AEC-Q200 standards
• Designed for high-temperature operation up to 130°C
• Utilizes a compact surface-mount package for PCB integration

Applications

• Automotive electronic circuit isolation
• Signal transmission in harsh thermal environments
• Pulse transformer applications requiring 1:1:1 ratio

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement, as environmental declarations may vary. Confirm that the required ET value of 17.2 Vµs aligns with the target circuit design specifications. Ensure the operating temperature range of -40°C to +130°C meets the system's thermal requirements. Validate the surface-mount footprint dimensions against the PCB layout to guarantee proper fitment.

Selection Notes

Select this component when a 1:1:1 isolated pulse transformer is required for automotive or industrial use. The 1.14 mH inductance and 17.2 Vµs ET value define its magnetic performance limits. Consider the -40°C to +130°C operating range for high-heat scenarios. The SMD package size of 8.64 x 6.73 x 3.56 mm dictates the available board space. Verify AEC-Q200 certification if automotive reliability is mandatory.

Part Context

This part belongs to the Pulse Transformers category within Pulse Electronics' portfolio. It is distinct from common mode chokes and power inductors offered by the same manufacturer. The PA0264NLT serves as an isolation component rather than a filtering or energy storage element. Its 1:1:1 configuration differentiates it from step-up or step-down transformer variants.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 1:1:1 ratio, 1.14 mH inductance, and 17.2 Vµs ET value. Physical compatibility must be verified against the 8.64 x 6.73 x 3.56 mm footprint. Thermal ratings and AEC-Q200 qualification should also be compared.
