H1100NLT

Overview

The H1100NLT is a LAN pulse transformer module manufactured by Pulse Electronics, designed for 10/100 Base-T Ethernet network applications. It features a surface mount (SMD/SMT) package with unshielded construction. The component supports a frequency range of 100 kHz to 100 MHz and provides an insulation voltage of 1.5 kV. Key electrical parameters include an inductance of 350 uH and a center tap-to-center tap resistance of 0.65 Ohms. It operates within a temperature range of 0°C to +70°C. The module has a single channel configuration with dimensions of 14.81 mm length, 11.68 mm width, and 5.13 mm height.

Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the component meets RoHS compliance requirements relevant to your target market regulations. Check for any specific moisture sensitivity level (MSL) handling instructions if storage conditions are a concern. Ensure the ordering suffix matches the required packaging type, such as cut tape or reel, as specified in the distributor catalog. Cross-reference the datasheet revision date to confirm the technical specifications have not been updated.

Selection Notes

Select the H1100NLT when designing systems requiring standard 10/100 Mbps Ethernet connectivity. This component is suitable for applications where space constraints allow for its specific SMD footprint. Consider the 350 uH inductance value for compatibility with standard PHY chip requirements. Verify that the operating temperature range of 0°C to +70°C aligns with the environmental conditions of the final product. Ensure the unshielded design does not conflict with electromagnetic interference (EMI) requirements of the system.

Part Context

The H1100NLT belongs to the family of LAN transformers produced by Pulse Electronics. These components are essential passive elements in Ethernet transceivers, providing signal coupling and isolation between the PHY chip and the external network medium. They are widely used in consumer electronics, industrial networking equipment, and computer hardware to facilitate reliable data transmission over twisted-pair cabling.
