Ⅲ.Main characteristics

Dual Connection Versatility:With a "Board to Board or Cable" style, the connector offers flexible installation options, adapting to both direct PCB-to-PCB interconnections and PCB-to-cable setups. This versatility reduces the need for multiple connector types in complex systems, simplifying design and inventory management.

Secure Through-Hole Mounting:Through-hole mounting ensures strong mechanical stability after soldering, resisting vibration and mechanical stress common in industrial equipment or automotive applications. This enhances long-term connection reliability compared to surface-mount alternatives in high-stress environments.

Standardized Mating Pitch:The 0.156" (3.96mm) mating pitch aligns with industry standards, ensuring compatibility with a wide range of complementary connectors (e.g., female headers) from Molex and other manufacturers. This interchangeability simplifies system upgrades and maintenance.

Optimized Contact Dimensions:With a mating contact length of 0.450" (11.43mm), post length of 0.140" (3.56mm), and overall contact length of 0.720" (18.29mm), the connector provides sufficient engagement depth for stable electrical contact while maintaining a compact form factor.

Reliable Contact Finish:The 15.0µin (0.38µm) thick mating contact finish minimizes electrical resistance, prevents corrosion,and ensures consistent signal transmission over time.This is critical for applications requiring low signal loss, such as data communication or power delivery circuits.

Ⅳ.Application field

Automotive Electronics:Applied in in-vehicle control units (e.g., HVAC systems, lighting controllers) and cable harnesses. The connector’s mechanical robustness withstands automotive vibration and temperature fluctuations, ensuring consistent performance in under-hood or cabin-mounted electronic systems.

Consumer Electronics:Incorporated into home appliances (e.g., washing machines, refrigerators) and desktop computers. Its dual connection style supports both internal PCB interconnections(e.g.,in computer motherboards) and external cable connections (e.g.,appliance control panels), meeting diverse design needs.

Medical Equipment:Utilized in diagnostic devices (e.g.,blood analyzers) and patient monitoring systems.The reliable contact finish and stable connection prevent signal interference, ensuring accurate data transmission—critical for medical applications where data precision impacts diagnosis and treatment.

Telecommunication Infrastructure:Used in network routers, switches, and data center servers.The standardized pitch and compatible design enable seamless interconnection between PCBs in high-density network equipment,supporting high-speed data transmission with minimal signal loss.

Ⅴ.Summary

In summary, the 41791-0836 rectangular connector from Molex excels in versatility, reliability, and compatibility. Its dual connection style, secure through-hole mounting, and standardized parameters make it adaptable to diverse applications—from industrial control to consumer electronics.
