PE-64995

Overview

The PE-64995 is a single-channel ISDN S-Interface pulse transformer manufactured by Pulse Electronics. Designed for through-hole mounting, it features a 1CT:2CT turns ratio and an inductance of 22 mH. The component operates within a temperature range of 0°C to 70°C and carries UL approval. It serves as an isolation and data interface solution for digital telecommunication applications requiring specific impedance matching and signal integrity.

Feature Summary

• Provides electrical isolation for ISDN S-Interface data transmission
• Encapsulated construction ensures mechanical stability and environmental protection
• Optimized magnetic core design supports high-frequency pulse signal fidelity

Applications

• ISDN terminal adapters
• Digital subscriber line equipment
• Telecommunications network interface units

Procurement Notes

Verify the specific suffix (e.g., NL) against the Bill of Materials to ensure compliance with RoHS directives and lead-free soldering requirements. Confirm that the through-hole package dimensions align with the target PCB footprint. Cross-reference the manufacturer's latest datasheet to validate active status and availability before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring precise 1CT:2CT coupling for ISDN protocols. Ensure the operating environment remains within the specified 0°C to 70°C thermal limits. Consider the 22 mH inductance value for low-frequency response requirements in the signal path. Validate that the encapsulation type meets the mechanical stress expectations of the assembly process.

Part Context

This part belongs to Pulse Electronics' portfolio of datacom and telecommunications transformers. It is specifically engineered for the ISDN market segment, distinguishing itself from general-purpose audio or power transformers. The product line emphasizes reliability in digital signal transmission environments where galvanic isolation is critical for system safety and noise immunity.

Replacement Considerations

The PE-64995NL is a verified equivalent variant offering identical electrical specifications with compliant packaging. No other direct substitute part numbers are confirmed in public documentation. Verify pinout compatibility and physical envelope dimensions before attempting any substitution with non-manufacturer components.
