With a nominal DC spark-over voltage of 120V (tested at 100V\/µs), it provides fast and accurate response, effectively diverting surge currents away from sensitive components and ensuring system stability.\u003c\/p\u003e\n\u003cp data-start=\"515\" data-end=\"1044\"\u003eUtilizing advanced ceramic gas discharge technology, the SMD4532-120NF delivers stable impulse spark-over performance at 1kV\/µs, along with high insulation resistance and low capacitance at 1 MHz. These characteristics make it ideal for high-speed communication systems and precision electronics 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 even under repeated surge conditions.\u003c\/p\u003e\n\u003cp data-start=\"1046\" data-end=\"1452\"\u003eCompared to lower voltage variants, the 120V model offers increased voltage tolerance and improved protection margins, making it suitable for a wide range of industrial and power-related applications. The SMD4532 package enhances thermal dissipation, supports higher surge handling capability, and provides robust mechanical strength, while enabling efficient surface-mount assembly for modern PCB designs.\u003c\/p\u003e\n\u003cp data-start=\"1454\" data-end=\"1473\"\u003e\u003cstrong data-start=\"1454\" data-end=\"1471\"\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1474\" data-end=\"1779\"\u003e\n\u003cli data-section-id=\"1egdkpw\" data-start=\"1474\" data-end=\"1515\"\u003eDC Spark-Over Voltage: 120V @ 100V\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"m23dwh\" data-start=\"1516\" data-end=\"1562\"\u003eStable impulse spark-over voltage @ 1kV\/µS\u003c\/li\u003e\n\u003cli data-section-id=\"19kifff\" data-start=\"1563\" data-end=\"1605\"\u003eHigh surge current capability (8\/20µS)\u003c\/li\u003e\n\u003cli data-section-id=\"i71dbo\" data-start=\"1606\" data-end=\"1654\"\u003eLow capacitance @ 1 MHz for signal integrity\u003c\/li\u003e\n\u003cli data-section-id=\"1d9sj2t\" data-start=\"1655\" data-end=\"1685\"\u003eHigh insulation resistance\u003c\/li\u003e\n\u003cli data-section-id=\"cpth1w\" data-start=\"1686\" data-end=\"1736\"\u003eEnhanced thermal performance (SMD4532 package)\u003c\/li\u003e\n\u003cli data-section-id=\"10hmw0c\" data-start=\"1737\" data-end=\"1779\"\u003eLong service life and high reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1781\" data-end=\"1800\"\u003e\u003cstrong data-start=\"1781\" data-end=\"1798\"\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul data-start=\"1801\" data-end=\"2048\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-section-id=\"1whba5f\" data-start=\"1801\" data-end=\"1842\"\u003eTelecom and networking infrastructure\u003c\/li\u003e\n\u003cli data-section-id=\"1ohxzbe\" data-start=\"1843\" data-end=\"1888\"\u003eIndustrial control and automation systems\u003c\/li\u003e\n\u003cli data-section-id=\"1mbxpmx\" data-start=\"1889\" data-end=\"1929\"\u003ePower supply and inverter protection\u003c\/li\u003e\n\u003cli data-section-id=\"18shwv3\" data-start=\"1930\" data-end=\"1965\"\u003eSmart grid and metering systems\u003c\/li\u003e\n\u003cli data-section-id=\"yxopth\" data-start=\"1966\" data-end=\"2006\"\u003eConsumer electronics and IoT devices\u003c\/li\u003e\n\u003cli data-section-id=\"1bdn01y\" data-start=\"2007\" data-end=\"2048\" 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":43759700803649,"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\/smd4532-120nf-gas-discharge-tubes-smd4532-package-ruilon","provider":"Hext by Regent Electronics","version":"1.0","type":"link"}
