C2267NLT

Overview

The C2267NLT is a dual-channel RF signal transformer manufactured by Pulse Electronics, designed for surface-mount technology (SMT) applications. It features a 1:1 impedance ratio with a primary and secondary coil impedance of 75 Ohms each. The component provides an inductance of 15 uH per channel and supports a maximum insulation voltage of 1.5 kV. Operating within a temperature range of 0°C to +70°C, it utilizes a shielded construction to minimize electromagnetic interference. The physical dimensions are 12.7 mm x 7.11 mm x 5.97 mm, packaged in reels for automated assembly.

Feature Summary

• Dual-channel configuration providing independent signal paths for balanced transmission
• Shielded design to reduce external electromagnetic interference and crosstalk
• High insulation voltage rating ensuring electrical isolation between circuits
• Surface-mount package optimized for high-volume automated PCB assembly

Applications

• 10Base-T Ethernet network interface implementations
• Balanced audio signal transmission circuits
• RF signal coupling and isolation stages
• Telecommunications equipment requiring impedance matching

Procurement Notes

Verify the specific suffix 'NLT' against the manufacturer's official datasheet to confirm reel packaging and tape specifications. Ensure the selected variant matches the required 15 uH inductance and 75 Ohm impedance parameters. Confirm RoHS compliance status and lead times directly with authorized distributors prior to ordering.

Selection Notes

Select this component when a dual-channel, shielded transformer with 1:1 ratio is required for 75 Ohm systems. Compare against alternatives like C2268NLT if different inductance values or package sizes are needed. Verify that the operating temperature range of 0°C to +70°C meets the environmental requirements of the target application.

Part Context

This part belongs to Pulse Electronics' portfolio of audio and signal transformers, specifically engineered for data communication and RF applications. It complements other LAN transformers in the series, offering a compact solution for integrating balanced lines into printed circuit boards while maintaining signal integrity through effective shielding.

Replacement Considerations

C2268NLT offers similar functionality but differs in inductance value (7.5 uH vs 15 uH). Cross-referencing with the official substitution guide is necessary to ensure electrical compatibility without modifying the circuit design.
