Product Overview

Sinyinda SYCDM27P12R1R2 (LCP Gold-Plated Edition) is a 12-pin high-density lithium battery connector male header (through-hole/SMT compatible) specifically designed for high-power-density 15A-class power/high-frequency signal hybrid transmission plus high-temperature SMT process scenarios. This product features a 2.7mm ultra-compact pitch with a 12-pin high-integration design, occupying only approximately 38mm of PCB width, saving 46% space compared to traditional 5.0mm 12-pin solutions. Combined with the high-performance LCP substrate, the heat deflection temperature is ≥340°C (1.8MPa), capable of withstanding 300°C lead-free reflow soldering peak temperatures (10-30s) without deformation, blistering, or warping. Key upgrade: the contact area adopts gold-plating technology (Au 0.05-0.1μm over Ni), significantly reducing contact resistance to ≤5mΩ, greatly enhancing oxidation resistance and fretting corrosion resistance, ensuring dual stable transmission of 15A high current and GHz-level high-frequency signals. Single-pin rated current is 15A, total current capacity is 180A, supporting flexible configurations of "6-pin power + 6-pin signal" or "8-pin power + 4-pin signal." It is particularly suited for applications with rigid requirements for "high density + high power + high-frequency high-speed + 300°C process," such as AI collaborative robot joint modules, industrial drone battery packs, humanoid robot servo interfaces, and high-end energy storage BMS sampling ports. It pairs precisely with the matching female connector SYCDF27P12CS1 to form a complete 15A-class 2.7mm-pitch high-density AI/drone lithium battery interconnection solution.

LCP Gold-Plated Edition 15A-Class 2.7mm Pitch 12-Pin Exclusive Core Advantages

• 2.7mm High-Density 12-Pin + 46% Space Saving:With a terminal center pitch of 2.7mm, the total width of 12 pins is only approximately 38mm (compared to approximately 65mm for a 5.0mm 12-pin solution), reducing PCB footprint by 46%, providing high-density interconnection possibilities for ultra-compact spaces such as AI robot joint modules and drone battery packs. At the same time, it maintains a 2.7mm safe pitch with creepage distance ≥2.0mm, meeting IPC-2221B safety requirements for 15A current carrying capacity.
• 15A Single-Pin Current Capacity + 180A Total Power:Single-pin continuous current capacity is 15A (temperature rise ≤30K@25°C), with 12 pins in parallel achieving up to 180A. It supports flexible configurations of "6-pin power + 6-pin signal" or "8-pin power + 4-pin signal," enabling integrated AI robot joint motor drive, encoder feedback, and temperature monitoring through the same port. Compared to traditional 5.0mm solutions, power density is increased by 60% within the same space.
• LCP Substrate Withstands 300°C Reflow Soldering + Low Dielectric Constant:Heat deflection temperature ≥340°C (1.8MPa), melting point 320°C, capable of withstanding 300°C lead-free reflow soldering peak temperatures (10-30s) without softening, blistering, or warping. Dielectric constant is 3.2 (1MHz) with a dissipation factor of 0.002, significantly superior to PA9T (4.5/0.01), ensuring GHz-level high-frequency signal transmission integrity and reducing signal reflection and crosstalk.
• Gold-Plated Contacts Low Impedance + Fretting Corrosion Resistance:The contact area features a gold plating layer (Au 0.05-0.1μm) over a nickel underlayer (Ni 2-3μm), with initial contact resistance ≤5mΩ (superior to the tin-plated version's 10mΩ). The chemically stable gold layer effectively prevents sulfidation, oxidation, and oxide film formation from fretting wear, ensuring excellent conductivity even after low-frequency mating cycles or prolonged idle periods. It is particularly suitable for weak signal transmission in high-frequency vibration environments of AI robots.
• Precision matching with mating connector + high reliability:Precisely matched with the SYCDF27P12CS1 receptacle, insertion/withdrawal force fluctuation < ±3N, with excellent tactile consistency; guide groove depth of 1.5mm supports blind mating; dual positioning posts with a height of 2.5mm provide PCB axial retention force ≥80N and radial retention force ≥50N, capable of withstanding high-frequency vibration (10-2000Hz, 15g) in AI robot joints and impact from drone takeoff and landing.
• Hybrid transmission architecture + EMC optimization:Power pins and signal pins are arranged alternately to reduce electromagnetic coupling interference; it is recommended that in PCB layout, the power pin trace width be ≥2.0mm (2oz copper thickness), and signal pins be impedance-matched; the LCP substrate's low moisture absorption (saturated water absorption rate of 0.04%) prevents dimensional expansion due to humidity changes that could affect high-frequency performance.
