With a nominal DC spark-over voltage of 300V (tested at 100V\/µs), it delivers fast and stable triggering, effectively diverting surge currents away from sensitive components and ensuring long-term system protection.\u003c\/p\u003e\n\u003cp data-start=\"529\" data-end=\"1058\"\u003eBuilt with advanced ceramic gas discharge technology, the SMD4532-300NF provides consistent impulse spark-over performance at 1kV\/µs, along with high insulation resistance and low capacitance at 1 MHz. This makes it highly suitable for high-speed communication lines and precision electronics where maintaining signal integrity is critical. Its strong impulse discharge current capability (8\/20µs waveform) and high impulse withstanding voltage ensure reliable operation and extended service life under repeated surge conditions.\u003c\/p\u003e\n\u003cp data-start=\"1060\" data-end=\"1479\"\u003eCompared to lower voltage variants, the 300V model offers significantly higher voltage tolerance and enhanced protection margins, making it ideal for industrial applications, power systems, and telecom infrastructure. The SMD4532 package enhances thermal dissipation, supports higher surge current handling, and ensures robust mechanical strength, while enabling efficient surface-mount assembly for modern PCB designs.\u003c\/p\u003e\n\u003cp data-start=\"1481\" data-end=\"1500\"\u003e\u003cstrong data-start=\"1481\" data-end=\"1498\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1501\" data-end=\"1806\"\u003e\n\u003cli data-section-id=\"3pxp7o\" data-start=\"1501\" data-end=\"1542\"\u003eDC Spark-Over Voltage: 300V @ 100V\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"m23dwh\" data-start=\"1543\" data-end=\"1589\"\u003eStable impulse spark-over voltage @ 1kV\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"19kifff\" data-start=\"1590\" data-end=\"1632\"\u003eHigh surge current capability (8\/20µS)\u003c\/li\u003e\n\u003cli data-section-id=\"i71dbo\" data-start=\"1633\" data-end=\"1681\"\u003eLow capacitance @ 1 MHz for signal integrity\u003c\/li\u003e\n\u003cli data-section-id=\"1d9sj2t\" data-start=\"1682\" data-end=\"1712\"\u003eHigh insulation resistance\u003c\/li\u003e\n\u003cli data-section-id=\"cpth1w\" data-start=\"1713\" data-end=\"1763\"\u003eEnhanced thermal performance (SMD4532 package)\u003c\/li\u003e\n\u003cli data-section-id=\"10hmw0c\" data-start=\"1764\" data-end=\"1806\"\u003eLong service life and high reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1808\" data-end=\"1827\"\u003e\u003cstrong data-start=\"1808\" data-end=\"1825\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1828\" data-end=\"2072\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1f42zxu\" data-start=\"1828\" data-end=\"1862\"\u003eTelecom and networking systems\u003c\/li\u003e\n\u003cli data-section-id=\"k7606u\" data-start=\"1863\" data-end=\"1910\"\u003eIndustrial automation and control equipment\u003c\/li\u003e\n\u003cli data-section-id=\"1mbxpmx\" data-start=\"1911\" data-end=\"1951\"\u003ePower supply and inverter protection\u003c\/li\u003e\n\u003cli data-section-id=\"1hkq8rn\" data-start=\"1952\" data-end=\"1989\"\u003eSmart grid and metering solutions\u003c\/li\u003e\n\u003cli data-section-id=\"yxopth\" data-start=\"1990\" data-end=\"2030\"\u003eConsumer electronics and IoT devices\u003c\/li\u003e\n\u003cli data-section-id=\"1bdn01y\" data-start=\"2031\" data-end=\"2072\" data-is-last-node=\"\"\u003eLightning and surge protection circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"z-0 flex min-h-[46px] justify-start\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"mt-3 w-full empty:hidden\"\u003e\n\u003cdiv class=\"text-center\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"RUILON","offers":[{"title":"Default Title","offer_id":43759721349185,"sku":null,"price":0.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0647\/4468\/5633\/files\/VARISTOR-01.png?v=1756461410","url":"https:\/\/hext.in\/products\/smd4532-300nf-gas-discharge-tubes-smd4532-package-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
