- ISDN Primary Rate Interface implementations
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status prior to ordering. Confirm that the moisture sensitivity level requirements align with your facility's reflow soldering profile. Ensure the SMD footprint matches the design layout exactly. Check for any lead-free manufacturing constraints if required by local regulations. Validate the operating temperature range against environmental conditions.
Selection Notes
Select this component when designing for T1, CEPT, or ISDN-PRI interfaces requiring a quad-port solution. The 1200 uH inductance value is critical for maintaining signal integrity in these specific telecom standards. Consider the physical dimensions of 28.58 x 12.32 mm for board space allocation. The 1.5 kV isolation rating ensures safety compliance for network connections.
Part Context
This part belongs to the Pulse Electronics audio and signal transformer family. It is specifically engineered for digital telecommunication networks. The module integrates magnetic components into a compact surface-mount package. It replaces older through-hole designs in modern PCB layouts.
