HRB 3.96mm Pitch Right Angle Header M3965R-N-K

HRB M3965R‑N‑K is a 3.96mm pitch single‑row right angle pin header designed for wire‑to‑board connections. Featuring through‑hole mounting and rear‑bend posts, it ensures stable PCB assembly and space‑saving routing. The housing is made of UL94 V‑0 rated polyester, while pins are brass with tin plating for low contact resistance. Rated at 7A AC/DC, 600V, with an operating temperature range of −40°C to +120°C, this header delivers excellent electrical performance and durability. Available in 2 to 20 pin configurations, it is cUL approved, RoHS compliant, and widely used in industrial control, power supplies, and consumer electronics.
