Product details

Product Description：

Huizhou Antenk Electronics Co., Ltd. manufactures MNJ03 series 2.54mm pitch open‑type mini jumpers to deliver flexible circuit short‑circuit and configuration switching for standard PCB pin header layouts, supporting 2 to 8 contact positions with dedicated A and B dimension values for each position variant and unified multi‑level dimensional tolerances to guarantee precise manual mounting onto matching pin headers. This mini jumper adopts PBT plus 30 percent glass fiber UL94V‑0 grade material as flame retardant insulator, phosphor bronze contacts support diverse plating alternatives covering gold flash, different thickness gold plating and tin over nickel plating options, electrically rated for 3A contact current, maximum 20mΩ contact resistance, minimum 500MΩ insulation resistance and 1000V AC per minute dielectric withstand voltage, operating reliably from minus 40 degrees Celsius to plus 105 degrees Celsius while complying with RoHS and REACH environmental standards, and provides multiple housing types and color selections to satisfy diverse project customization demands. This compact configuration jumper is widely applied in liquid crystal display modules, digital cameras, communication hardware, industrial control panels, portable storage devices, digital household appliances, electronic toys, computer peripherals, automotive electronic assemblies and precision measuring instruments requiring convenient circuit setting adjustment. Operators need to select proper position count and plating grade according to circuit requirements, complete manual assembly aligned with PCB pin headers, avoid violent squeezing to prevent insulator cracking and contact deformation, and store finished jumpers inside dry sealed packages to protect contact plating layers. Unlike competitors outsourcing mold stamping and plating procedures Antenk carries out complete in‑house production workflow covering self‑developed precision plastic and metal mold fabrication, phosphor bronze contact stamping, high‑temperature PBT injection molding, multi‑option gold and tin electroplating plus full‑set laboratory reliability verification, holding ISO9001 ISO14001 IATF16949 and UL E472792 certifications. We own over two hundred fifty plastic connector molds and one hundred eighty metal terminal molds, deliver custom type color and plating solutions, offer round‑the‑clock professional engineering support, and more than seventy percent of our jumper products are exported globally backed by ANTENK brand and stable mass‑production quality.

1. PBT GF UL94V 0 Jumper Insulator delivers reliable flame retardant performance and mechanical strength for long term PCB circuit configuration applications.

2. Phosphor Bronze Jumper Contact maintains stable electrical conduction under 3A working current for frequent jumper installation and removal operations.

3. Multi Plating Mini Jumper Cap supports various gold and tin plating choices to satisfy different anti corrosion and cost requirements of electronic projects.
