Product Overview

The Sinyinda SYCBCHF01P5DIP is a 5Pin high-current female connector (solder wire type) designed for 100A-class pure power lithium battery transmission scenarios. This product adopts 5 identical 20A power terminals, supporting 5 parallel current-sharing paths to achieve 100A continuous current capacity, and features true N+3 ultra-high redundancy capability—even if a single pin fails, the remaining 4 pins can still carry 80A normal load; with two pins failed, it maintains 60A emergency operation; with three pins failed, it still supports 40A safe return/shutdown. It adopts copper nickel-plated (50-80μ") high-wear-resistant contact technology, with a mating cycle life of ≥1000 times and stable contact resistance ≤3mΩ; the PA66 insulating substrate balances mechanical strength and temperature resistance, with a rated voltage of DC 250V and an operating temperature range of -40℃~+105℃. The five-hole positioning design ensures installation accuracy of ±0.1mm, the asymmetric housing provides physical reverse-connection protection, and the recommended mating cycle life is 1000 times. The U-slot structure supports direct press-in soldering of AWG 10-18 gauge wires without pre-tinning, greatly improving assembly efficiency. It is particularly suited for application scenarios with rigid requirements for "100A-class power + flexible wiring + manual/semi-automatic assembly + ultimate redundancy," such as TWS earbud charging case super-fast charging ports, smartwatch magnetic charging bases, micro drone battery interfaces, and medical portable device power modules, and pairs precisely with the male connector SYCBCHM01P5R1 to form a complete 100A-class solder wire lithium battery interconnection solution.

Core Advantages Exclusive to 100A Solder Wire Power Terminals (5×20A Current Sharing Version)

• 5×20A Homogeneous Terminals + N+3 Ultra-High Redundancy Architecture:The 5 terminals are completely identical in size, material, plating, and pad specifications, with an initial contact resistance deviation of <5%, ensuring a current distribution deviation of <±3% across all pins under 100A load; when a single pin fails, the remaining 4 pins automatically share the current to carry 80A normal load; with two pins failed, it maintains 60A emergency operation; with three pins failed, it still supports 40A safe return/shutdown, improving system availability to 99.99% and extending MTTR from emergency repair to planned maintenance windows.
• Copper-Nickel Plated (50-80μ") High-Wear-Resistant Contacts:The nickel plating thickness reaches 50-80μ" (1.27-2.03μm), with a hardness of HV400-500, mating wear of <0.1μm per cycle, and a contact resistance change rate of <10% after 1000 mating cycles; the nickel layer exhibits excellent chemical stability, with salt spray corrosion resistance of >96h (5% NaCl), making it suitable for outdoor smart wearables, sweat environments in sports earphones, and high-altitude low-temperature conditions for drones, at a cost of only 1/5 of gold-plating solutions.
• High-Strength PA66 Substrate for Load Bearing:Tensile strength ≥80MPa, flexural strength ≥120MPa, capable of withstanding frequent open/close impact of TWS earbud charging cases (5,000 cycles without cracking) and vibration from micro-drone drops; CTI value ≥250V, meets UL94 V0 flame retardancy rating, heat deflection temperature ≥240℃ (1.8MPa), short-term tolerance of 150℃ peak temperature without softening, ensuring housing deformation-free under 100A transient surge.
• U-Slot Wire Crimping Structure + No Pre-Tinning Required:The U-slot (width 2.5mm, depth 1.8mm) is designed at the bottom of the terminal, supporting direct press-in of AWG 10-18 gauge wires followed by soldering, without the need for pre-tinning or crimping terminals, greatly simplifying the assembly process; solder joint fullness is improved by 30%, and the cold solder joint rate is reduced to <0.1%.
• Asymmetric housing + guide groove dual keying:The housing features a trapezoidal profile with asymmetric guide rib grooves, ensuring the 5-pin position is uniquely matched, completely eliminating reverse insertion risks; the guide groove depth is 2.5mm, ensuring all contacts are fully aligned before mating, preventing arc damage during live insertion/removal, and supporting blind mating operations.
• -40℃~+105℃ wide-temperature current-sharing stability:The PA66 base material has been modified for low-temperature toughness, with no cracking on impact at -40°C; at high temperatures up to 105°C, the simultaneous rise rate of contact resistance across the 5 pins is <8%, preventing current sharing imbalance or redundancy failure due to temperature drift differences; the optional sealing O-ring has a compression set rate of <20%, maintaining IP54 protection over long-term use.
