Overview
The Pulse Electronics 23Z104SM is a discontinued surface-mount common mode choke designed for signal line applications. It features four independent channels with an inductance of 68 uH and a maximum DC resistance of 200 mOhms per channel. The component operates within a temperature range of 0°C to +70°C and has physical dimensions of 5.84 mm length, 6.73 mm width, and 5.59 mm height. It utilizes an unshielded design and is housed in an 8-SOIC package.
Feature Summary
- Provides common mode noise suppression for four-channel signal lines
- Surface-mount construction for automated PCB assembly
- Unshielded magnetic core design
Applications
- LAN interface circuit protection
- Signal line filtering in electronic equipment
- Common mode interference reduction in data transmission paths
Procurement Notes
This component is officially obsolete and no longer manufactured by Pulse Electronics. Procurement is limited to existing surplus stock from distributors. Verify the authenticity of available units and check RoHS compliance status, as the original specification indicates non-compliance. Ensure supply chain stability before finalizing designs requiring this specific part number.
Selection Notes
Designers should consider the 23Z104SMNL as a direct replacement due to its identical electrical characteristics and form factor. Evaluate alternative components if long-term supply assurance is required, as the current model is end-of-life. Confirm that substitute parts meet the same inductance and current handling requirements for the intended application.
Part Context
The 23Z104SM belongs to the Pulse Electronics LAN Choke series, specifically engineered for Ethernet and similar high-speed data interfaces. It serves as a passive filter to attenuate electromagnetic interference on twisted pair cables. The product line focuses on compact solutions for modern communication hardware.
Replacement Considerations
The 23Z104SMNL is confirmed as a direct substitute. Both parts share identical electrical parameters and pin configurations, allowing for drop-in replacement in existing layouts without schematic modifications.
