SL 11 139 18 G

Headers, Male Pins Overview

The SL 11 139 18 G is a single-row male pin header connector manufactured by Fischer Elektronik. It features a 0.635 mm pitch and contains 18 positions. The contacts are constructed from copper-tin alloy with gold plating, ensuring low contact resistance of ≤5 mΩ. Rated for 3 A current and 250 V AC voltage, it withstands 2000 V dielectric strength. The insulator is made of PA 4.6 (polyamide) with UL 94 V-0 flammability rating. Designed for through-hole mounting, the connector operates within a temperature range of -40°C to +163°C and supports soldering at 260°C for 10 seconds.

Headers, Male Pins Feature Summary

• Low profile design utilizing gold-plated copper-tin alloy contacts for reliable signal transmission
• High thermal stability with polyamide insulation rated for temperatures up to 163°C
• Robust electrical isolation meeting 2000 V dielectric strength requirements

Headers, Male Pins Applications

• General purpose board-to-board interconnections
• Industrial control system circuit boards
• Electronic equipment requiring high reliability headers

Headers, Male Pins Procurement Notes

Verify that the specific part number suffix matches the required contact plating and pin count. Confirm that the through-hole mounting style aligns with the target PCB layout. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the datasheet for exact dimensional tolerances before integration.

Headers, Male Pins Selection Notes

Select this component when a low-profile single-row header is required for dense circuit layouts. The gold plating offers superior corrosion resistance compared to tin-only options. Consider the 0.635 mm pitch for applications needing finer spacing than standard 2.54 mm headers. Verify that the 3 A current rating suffices for the intended power distribution needs.

Headers, Male Pins Part Context

This component belongs to the SL 11 series of male pin headers from Fischer Elektronik. The series offers various pin counts and pitch options for different connectivity needs. The SL 11 139 18 G specifically addresses applications requiring a compact, high-reliability connection point with gold-plated contacts for enhanced durability in demanding environments.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Fischer Elektronik SL 11 series headers with identical 18-pin configurations and 0.635 mm pitch. Ensure replacement parts maintain the same gold-plated contact material and PA 4.6 insulation properties to preserve electrical and thermal performance standards.
