BKT-141-03-L-V-S

Headers, Male Pins Overview

The BKT-141-03-L-V-S is a polarized micro terminal strip manufactured by Samtec. It features a 1.00 mm pitch and a 2.54 mm row spacing, configured with 41 positions in a dual-row arrangement. The connector utilizes surface mount technology (SMD/SMT) for straight installation on printed circuit boards. Contacts are male pins made of phosphor bronze with gold plating, rated for 2.8 A current. The housing is constructed from black liquid crystal polymer (LCP), offering UL 94 V-0 flammability rating. Operating temperature range spans from -55°C to +125°C.

Headers, Male Pins Procurement Notes

Verify the complete part number including suffixes such as -S for tape-and-reel packaging or -A for alternative configurations against official Samtec documentation. Confirm that the specific variant matches the required mechanical and electrical specifications for the target application. Cross-reference RoHS compliance status and material declarations with current manufacturer data sheets to ensure regulatory adherence before procurement.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required with precise polarization. The 1.00 mm pitch allows for significant I/O density within constrained board areas. Ensure the design supports surface mount reflow processes. Consider the 2.8 A per contact rating for power distribution needs. Verify that the operating environment stays within the specified -55°C to +125°C thermal limits for long-term reliability.

Headers, Male Pins Part Context

This part belongs to the BKT series of flexible board stacking headers from Samtec. These components are designed for applications requiring robust connections between closely spaced PCBs. The series offers various stacking heights and termination options to suit different mechanical constraints. The BKT-141-03-L-V-S specifically represents a standard configuration within this family, balancing density with ease of assembly.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Samtec BKT variants with identical pitch and row count but different stacking heights or termination styles. Verify compatibility with mating sockets such as the TMS series. Ensure any replacement maintains the same polarization keying and electrical ratings to preserve system integrity without redesigning the footprint.

Headers, Male Pins FAQ

What is the primary function of the polarization feature in this connector?
