0.25mm Thin Phosphor Bronze Tab serves as the core elastic conductive part of this SMT battery contact and maintains steady clamping force for CR2025 and CR2032 coin cells.
4um Uniform Nickel Coated Tab forms a complete anti-rust barrier on the phosphor bronze substrate to reduce contact resistance and extend product service life.
Wide Temp SMT Coin Cell Spring keeps stable elastic and conductive performance under operating temperature from -40℃ to 270℃ for diverse electronic equipment.
