Product Overview

The SYCBCHF01P5CSMT from SYC is a 5Pin high-current female connector (SMT version) designed specifically for 100A-class pure power lithium battery transmission scenarios. This product features 5 identical 20A power terminals, supporting 5-way parallel current sharing to achieve 100A continuous current capacity, and offers true N+1 redundancy—even if a single pin fails, the remaining 4 pins can still carry an 80A regular load without interrupting power supply. It adopts a copper nickel-plated (50-80μ") high-wear-resistant contact process, with a mating cycle life of ≥1000 times and stable contact resistance of ≤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℃ to +105℃. The five-hole positioning design ensures SMT accuracy of ±0.1mm, the asymmetric housing provides physical anti-reverse insertion protection, and the recommended mating cycle life is 1000 times. It is particularly suited for application scenarios with rigid demands for "100A-class power + fully automated assembly + zero manual intervention," such as TWS earphone charging case 100W fast-charge 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 SMT lithium battery interconnect solution.

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

• 5×20A Homogeneous Terminals + N+1 Redundant Architecture:All 5 terminals are completely identical in size, material, plating, and pad specifications, with initial contact resistance dispersion of <5%, ensuring current distribution deviation of <±3% across each pin under 100A load; when a single pin fails due to contamination/damage/aging, the remaining 4 pins automatically share current to carry 80A of normal load, the system does not require shutdown, MTTR is extended from emergency repair to planned maintenance windows, and availability is improved to 99.9%.
• 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.
• SMT automatic placement process compatibility:Terminal pad size standardization (3.0×2.5mm), compatible with mainstream reflow soldering curves (peak temperature 245℃±5℃, duration 60-90s); five-hole positioning design (Φ1.85mm) ensures placement accuracy of ±0.1mm, preventing misalignment that could cause cold solder joints or short circuits; for mass production, AOI optical inspection + X-Ray penetration dual verification is recommended to ensure full, void-free solder joints.
• 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.
