Overview
The PE-64995NL is a pulse transformer manufactured by Pulse Electronics, designed for ISDN S-interface applications. It features a single-turn primary to two-turn secondary configuration (1CT:2CT) with an inductance of 22mH and a resistance of 4.3 Ohms. The component utilizes a through-hole mounting style and operates within a temperature range of 0°C to 70°C. Its encapsulated construction ensures isolation and data interface integrity for signal transformers.
Feature Summary
- Provides electrical isolation and data interface capabilities for ISDN S-interface systems
- Features a 1CT:2CT turns ratio for signal transformation
- Utilizes an encapsulated design for structural protection
Applications
- ISDN S-interface signal processing
- Data interface isolation circuits
- Pulse transformer applications requiring encapsulation
Procurement Notes
Verify the specific datasheet version when sourcing, as distributor listings may vary in detail. Confirm that the through-hole package matches the target PCB footprint requirements. Ensure the operating temperature range of 0°C to 70°C aligns with the final assembly environment specifications before integration.
Selection Notes
Select this component specifically for ISDN S-interface designs requiring a 1CT:2CT configuration. The 22mH inductance value is critical for maintaining signal integrity in these specific interface protocols. Consider the physical dimensions and through-hole installation method during the mechanical layout phase to ensure proper clearance and mounting stability.
Part Context
This part belongs to the Pulse Electronics audio and signal transformer family, specifically targeting telecommunications interfaces. It serves as a specialized component for digital voice and data transmission standards, distinguishing itself from general-purpose power transformers through its precise turns ratio and encapsulated signal handling capabilities.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility carefully if considering alternative sources, as the specific 1CT:2CT ratio and encapsulation type are unique to this model.
