JST R Insulated Ring Terminal 4 mm Stud Size 12 AWG 10 AWG Wire Size Yellow FVDWS5.5-S4(LF)

The JST FVDWS5.5-S4(LF) is an R-series insulated ring terminal engineered for professional electrical and electronic applications. Featuring oxygen-free copper contact material, it offers excellent electrical characteristics ensuring minimal resistance and reliable connectivity in critical circuits. This terminal supports wire sizes from 12 AWG to 10 AWG, suitable for various power and signal wiring needs.

The terminal's vinyl insulation provides high flame resistance and electrical isolation to prevent short circuits and enhance safety. The flared vinyl insulation with a butted seam design facilitates easier wire insertion and effective crimping, resulting in a secure mechanical and electrical connection. This ring terminal is rated to withstand temperatures up to 105 °C, making it suitable for demanding industrial environments.

Its 4 mm stud size and precise ring dimensions (7.2 mm outer diameter and 4.3 mm inner diameter) ensure compatibility with standardized terminal posts and studs. With an overall length of 23.5 mm and 1 mm thickness, it balances durability with compactness. The JST insulated Ring Terminal is ideal for use in power connectors within electronic components, automotive, HVAC, manufacturing, and industrial electrical systems.

Key features include high-strength brazing for mechanical integrity, flame-retardant vinyl insulation, and compatibility with 12 to 10 AWG wiring standards. The yellow color insulation allows easy identification of wire gauge and terminal type during installation and maintenance.
