100B-2002

Overview

The iNRCORE, LLC 100B-2002 is a LAN pulse transformer designed for 10/100 Base-T Ethernet applications. It features a 1:1 turns ratio and a typical inductance of 350µH. The component utilizes a surface mount package with dimensions of 0.518 inches in length and 0.595 inches in width. This module supports dual channel operation within a compact form factor suitable for high-density circuit board layouts.

Feature Summary

• Supports 10/100 Base-T Ethernet data transmission standards
• Provides galvanic isolation via integrated magnetic coupling
• Designed for surface mount technology assembly processes

Applications

• Ethernet network interface cards
• LAN port connectors on embedded systems
• Industrial communication modules requiring 10/100 Mbps connectivity

Procurement Notes

Verify the specific suffix variant (e.g., XT, NL, FXNL) required for your design, as packaging and lead times vary by configuration. Confirm RoHS compliance status, as some variants may be non-compliant. Ensure the chassis or PCB layout accommodates the specified surface mount footprint dimensions before finalizing procurement orders.

Selection Notes

Select this component when a 1:1 impedance transformation is required for balanced-to-unbalanced signal conversion in Ethernet PHY interfaces. Consider the 350µH inductance value for common mode rejection requirements. Evaluate the physical size constraints against the 0.518 x 0.595 inch package dimensions to ensure adequate clearance on the target printed circuit board.

Part Context

This part belongs to the iNRCORE LAN transformer family, which provides magnetics solutions for various Ethernet speeds. The 100B series specifically targets 10/100 Base-T applications, distinguishing it from higher-speed Gigabit or PoE-enabled transformer lines. It serves as a critical passive component for signal integrity in wired networking hardware.

Replacement Considerations

Direct substitutes include other 10/100 Base-T pulse transformers with identical 1:1 ratios and compatible surface mount footprints. Verify pinout compatibility and inductance specifications before swapping. Variants such as 100B-2002XT or 100B-2002NL offer different packaging options but maintain core electrical equivalence.
