M20-9990545

Headers, Male Pins Overview

The M20-9990545 is a 5-position single in-line (SIL) vertical pin header from the Harwin M20 series. It features a 2.54 mm contact pitch and is designed for through-hole mounting on printed circuit boards. The connector utilizes gold-plated brass contacts to ensure reliable signal transmission, housed within a black UL94V-0 polyamide (nylon) 6T body. It supports a maximum current rating of 3A and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Vertical orientation design facilitates direct board-to-board or wire-to-board connections with standard mating heights.
• Gold-plated brass contacts provide durable electrical performance and resistance to corrosion over repeated operations.
• UL94V-0 rated polyamide housing ensures flame retardancy and mechanical stability in industrial environments.

Headers, Male Pins Applications

• Industrial control systems requiring robust interconnects
• Consumer electronics assembly
• Automotive electronic modules

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required contact count and orientation. Confirm RoHS compliance status if restricted substances are mandated by your project specifications. Ensure the supplier provides original manufacturer documentation to guarantee authenticity and traceability of the components.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row vertical header is needed for dense PCB layouts. The 2.54 mm pitch is compatible with standard breadboard and ribbon cable systems. Consider the 3A current rating for power distribution lines and verify that the operating temperature range meets the environmental conditions of the final application.
