Detailed Description

Introducing the 39-31-0048, a Mini-Fit Jr. Vertical Header designed for high-performance connectivity in electronic applications. With a pitch of 4.20mm and featuring a dual-row configuration, this header offers reliable power and signal transmission. Boasting 4 circuits and constructed without a snap-in plastic peg PCB lock, it facilitates easy installation. The gold-plated brass contacts ensure excellent conductivity, rated for up to 9A and 600V. Engineered for durability, the nylon body is suitable for a wide range of operating environments, withstanding temperatures from -40 to 105°C. PCB retention is enhanced through a built-in locator, while polarization to both the PCB and mating part guarantees proper alignment. RoHS compliant and lead-free process capable, this header is a dependable choice for wire-to-board connections in various electronic devices.
