L77DB25SF179 is a subminature connector designed for reliable electrical interconnections in compact applications. The connector features a tinned steel shell with a flame-retardant glass-filled thermoplastic body (UL 94 V-0), brass contacts with gold-over-nickel finish on the mating area, and operates across a temperature range of -55°C to +85°C. It provides voltage proof greater than 1000 V RMS at 50 Hz, with nominal current ratings of 7.5 A (size 20) or 20 A (size 8), contact resistance below 5 mO, and insulator resistance exceeding 5000 MO. The connector is suitable for applications requiring compact, high-reliability interconnections in industrial, aerospace, and instrumentation systems where environmental durability and electrical performance are essential.
