The JWH-3.5 is a versatile medium-light marine-grade non-resonant peak vibration isolator engineered for shipboard radar displays, control panels, and electronic instruments with a nominal load of 35 Newtons. Offering a load range of 30–40N, this isolator bridges the gap between ultra-light navigation terminals and heavier machinery monitoring equipment. Featuring a low natural frequency of ≤7Hz and carefully optimized damping characteristics, it effectively suppresses resonance peaks while providing robust vibration and shock isolation across a wide frequency spectrum. With a loaded working height of 51mm ±1mm, it provides vertical displacement limits of 5mm upward, 8mm downward, and 8mm horizontal. Built to withstand the demanding conditions of marine service, the JWH-3.5 offers exceptional resistance to oil, seawater, salt spray, and UV radiation, with a 10-year service life. It is the ideal choice for bridge electronics, engine room monitoring displays, and deck-mounted instrument
