With a nominal DC spark-over voltage of 420V (tested at 100V\/µs), it provides fast and reliable activation, effectively diverting surge currents away from sensitive components and ensuring stable system operation.\u003c\/p\u003e\n\u003cp data-start=\"533\" data-end=\"1088\"\u003eManufactured using advanced ceramic gas discharge technology, the SMD4532-420NF offers stable impulse spark-over characteristics at 1kV\/µs, along with high insulation resistance and low capacitance at 1 MHz. These features make it highly suitable for high-speed communication lines and precision electronic systems where signal integrity is critical. Its strong impulse discharge current capability (8\/20µs waveform) and excellent impulse withstanding voltage ensure long service life and consistent protection performance under repeated surge conditions.\u003c\/p\u003e\n\u003cp data-start=\"1090\" data-end=\"1507\"\u003eCompared to lower voltage variants, the 420V model provides increased voltage tolerance and enhanced protection margins, making it ideal for demanding industrial applications, telecom infrastructure, and power systems. The SMD4532 package delivers superior thermal dissipation, higher surge handling capability, and robust mechanical strength, while supporting efficient surface-mount assembly for modern PCB designs.\u003c\/p\u003e\n\u003cp data-start=\"1509\" data-end=\"1528\"\u003e\u003cstrong data-start=\"1509\" data-end=\"1526\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1529\" data-end=\"1834\"\u003e\n\u003cli data-section-id=\"s1z281\" data-start=\"1529\" data-end=\"1570\"\u003eDC Spark-Over Voltage: 420V @ 100V\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"m23dwh\" data-start=\"1571\" data-end=\"1617\"\u003eStable impulse spark-over voltage @ 1kV\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"19kifff\" data-start=\"1618\" data-end=\"1660\"\u003eHigh surge current capability (8\/20µS)\u003c\/li\u003e\n\u003cli data-section-id=\"i71dbo\" data-start=\"1661\" data-end=\"1709\"\u003eLow capacitance @ 1 MHz for signal integrity\u003c\/li\u003e\n\u003cli data-section-id=\"1d9sj2t\" data-start=\"1710\" data-end=\"1740\"\u003eHigh insulation resistance\u003c\/li\u003e\n\u003cli data-section-id=\"cpth1w\" data-start=\"1741\" data-end=\"1791\"\u003eEnhanced thermal performance (SMD4532 package)\u003c\/li\u003e\n\u003cli data-section-id=\"10hmw0c\" data-start=\"1792\" data-end=\"1834\"\u003eLong service life and high reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1836\" data-end=\"1855\"\u003e\u003cstrong data-start=\"1836\" data-end=\"1853\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1856\" data-end=\"2099\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1whba5f\" data-start=\"1856\" data-end=\"1897\"\u003eTelecom and networking infrastructure\u003c\/li\u003e\n\u003cli data-section-id=\"xwcxty\" data-start=\"1898\" data-end=\"1931\"\u003eIndustrial automation systems\u003c\/li\u003e\n\u003cli data-section-id=\"1mbxpmx\" data-start=\"1932\" data-end=\"1972\"\u003ePower supply and inverter protection\u003c\/li\u003e\n\u003cli data-section-id=\"vupg7q\" data-start=\"1973\" data-end=\"2006\"\u003eSmart grid and energy systems\u003c\/li\u003e\n\u003cli data-section-id=\"yxopth\" data-start=\"2007\" data-end=\"2047\"\u003eConsumer electronics and IoT devices\u003c\/li\u003e\n\u003cli data-section-id=\"e8q97u\" data-start=\"2048\" data-end=\"2099\" data-is-last-node=\"\"\u003eLightning and transient 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":43759740747841,"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\/smd4532-420nf-gas-discharge-tubes-smd4532-package-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
