• Surface mount construction for automated assembly

Pulse Transformers Applications

• T3/DS3/E3/STS-1 telecommunications interfaces
• High-frequency signal isolation circuits
• Transceiver interface modules

Pulse Transformers Procurement Notes

Verify the specific suffix (NL vs NLT) to confirm packaging type, as NL indicates tube packaging while NLT indicates tape and reel. Confirm moisture sensitivity handling procedures are followed during storage and reflow soldering. Ensure the operating temperature range of -40°C to +85°C aligns with the target application environment. Check for UL recognition status updates on specific variants.

Pulse Transformers Selection Notes

Select this component when a single-channel transformer for T3/DS3/E3/STS-1 standards is required. The 40µH inductance and 1:2CT ratio are critical for impedance matching in these specific telecom protocols. Consider the physical footprint of 7x7 mm for PCB layout constraints. Verify compatibility with the specific transceiver IC used in the design.

Pulse Transformers Part Context

The T3002NL belongs to the T3/DS3/E3/STS-1 transformer family from Pulse Electronics. These components are specialized for high-speed digital telecom signals. The NL suffix denotes tube packaging, distinct from the NLT variant which uses tape and reel. This series is engineered to meet strict return loss specifications defined in G.703 standards.

Pulse Transformers Replacement Considerations

The T3002NLT is a direct functional equivalent differing only in packaging format (tape and reel instead of tube). Cross-referencing with other manufacturers requires verifying identical inductance, turns ratio, and thermal ratings.
