O projeto deve considerar espa&ccedil;amento t&eacute;rmico e evitar opera&ccedil;&atilde;o pr&oacute;xima ao limite de tens&atilde;o cont&iacute;nua.</p><h2>Estrat&eacute;gia de Posicionamento</h2><p>Posicionar o MOV na entrada de energia com trilhas curtas.   Instalar entre fase e neutro para prote&ccedil;&atilde;o diferencial.   Adicionar MOV fase-terra conforme a categoria de surto.</p><h2>Arquitetura de Prote&ccedil;&atilde;o em Camadas</h2><p>O MOV absorve alta energia, por&eacute;m a tens&atilde;o residual pode exigir um clamp secund&aacute;rio no barramento DC e um choke de modo comum para reduzir o estresse nos circuitos de controle.</p><h2>Exemplo de Aplica&ccedil;&atilde;o AC-DC</h2><p>Entrada 230 VCA com requisito de surto de 1 kV linha-linha e 2 kV linha-terra.   Utilizar MOV 14D entre fase e neutro com imped&acirc;ncia em s&eacute;rie antes da ponte retificadora.   Verificar a tens&atilde;o no barramento DC durante o surto.</p><h2>M&eacute;todo de Verifica&ccedil;&atilde;o</h2><p>Medir a tens&atilde;o de clamping no barramento DC.   Monitorar a temperatura do MOV em surtos repetitivos.   Verificar corrente de fuga ap&oacute;s testes.   Validar recupera&ccedil;&atilde;o funcional do sistema.</p><h2>Par&acirc;metros Necess&aacute;rios</h2><p>Tens&atilde;o RMS CA e toler&acirc;ncia   N&iacute;vel de surto e modo de acoplamento   Forma de onda de corrente de pico   N&uacute;mero de pulsos   Tens&atilde;o m&aacute;xima de clamping   Espa&ccedil;o dispon&iacute;vel na PCB</p><h2>Conclus&atilde;o</h2><p>A conformidade com a IEC 61000-4-5 requer sele&ccedil;&atilde;o de MOV baseada em energia, corrente de pico, di&acirc;metro do disco e posicionamento adequado. A prote&ccedil;&atilde;o coordenada reduz o estresse residual e aumenta a confiabilidade do sistema.</p><figure class="ts-video"> <iframe src="https://www.youtube.com/embed/RAF4Dgb-oQk" title="Prote&ccedil;&atilde;o contra surtos com varistor MOV" loading="lazy" allowfullscreen=""></iframe> </figure><div class="ts-cta"><a href="https://www.suntan.com.hk/Varistor/?utm_source=blog&amp;utm_medium=referral&amp;utm_campaign=varistor_20260225" class="ts-btn ts-primary">Ver especifica&ccedil;&otilde;es dos varistores</a>  <a href="https://www.suntan.com.hk/contact.html?utm_source=blog&amp;utm_medium=referral&amp;utm_campaign=varistor_20260225" class="ts-btn ts-outline">Solicitar suporte de engenharia</a></div></article></p><p>&nbsp;</p>]]></description><category>Varistor</category><comments>https://www.capacitor.com.hk/capacitors/varistor-oxido-metalico-iec-61000-4-5-protecao-contra-surtos.html#comment</comments><wfw:comment>https://www.capacitor.com.hk/</wfw:comment><wfw:commentRss>https://www.capacitor.com.hk/feed.asp?cmt=1223</wfw:commentRss><trackback:ping>https://www.capacitor.com.hk/cmd.asp?act=tb&amp;id=1223&amp;key=907b8dfd</trackback:ping></item><item><title>Suntan Varistor – Dipped Varistor / SMD Varistor</title><author>a@b.com (admin)</author><link>https://www.capacitor.com.hk/capacitors/Suntan-Varistor-Dipped-Varistor-SMD-Varistor.html</link><pubDate>Wed, 23 Dec 2020 14:28:40 +0800</pubDate><guid>https://www.capacitor.com.hk/capacitors/Suntan-Varistor-Dipped-Varistor-SMD-Varistor.html</guid><description><![CDATA[<p>Suntan Technology Company Limited<br />---All Kinds of Capacitors<br /><br />Дорогие друзья,<br /><br /><a href="https://www.suntan.com.hk/Varistor/" target="_blank">Варистор</a>&nbsp;также известен как резистор, зависимый от напряжения, или VDR. Suntan поддерживает хороший и качественный варистор. Это отличалось слабым обжигом, диффузией серебра, зернистостью, электрическими свойствами.<br /><br />Стандартная рабочая температура для этого продукта составляет -55 ~ + 125 &deg; C.<br />Рабочее напряжение составляет 3,3 В - 68 В<br />Низкий ток утечки, соответствует требованиям ROHS;<br />Размеры включают 0402, 0603, 0805, 1206, 1210, 1812, 2220.<br /><br />Если у вас есть вопросы, отправьте запрос нам на&nbsp;<a href="mailto:sales@suntan.com.hk" target="_blank">sales@suntan.com.hk<br /><br /><img src="https://www.capacitor.com.hk/upload/Suntan-Su-Dipped-Varistor.jpg" alt="" title="" /></a></p>]]></description><category>Varistor</category><comments>https://www.capacitor.com.hk/capacitors/Suntan-Varistor-Dipped-Varistor-SMD-Varistor.html#comment</comments><wfw:comment>https://www.capacitor.com.hk/</wfw:comment><wfw:commentRss>https://www.capacitor.com.hk/feed.asp?cmt=994</wfw:commentRss><trackback:ping>https://www.capacitor.com.hk/cmd.asp?act=tb&amp;id=994&amp;key=00a2dd0b</trackback:ping></item><item><title>Suntan SMD варистор паспорт обновляется</title><author>a@b.com (admin)</author><link>https://www.capacitor.com.hk/capacitors/538.html</link><pubDate>Tue, 03 Nov 2015 09:46:31 +0800</pubDate><guid>https://www.capacitor.com.hk/capacitors/538.html</guid><description><![CDATA[<div><span style="font-size: smaller;"><span style="font-family: Arial;">Suntan Technology Company Limited</span></span><div><span style="font-size: smaller;"><span style="font-family: Arial;">---All Kinds of Capacitors</span></span><div><span style="font-size: smaller;"><span style="font-family: Arial;"><br />AC Информация рабочее напряжение просто добавляется к спецификации наших SMD варисторы.</span></span><div><span style="font-size: smaller;"><span style="font-family: Arial;">Подробнее, пожалуйста, проверьте:&nbsp;</span></span><a href="http://www.capacitors.hk/Varistor/TSVC.pdf" target="_blank"><span style="font-size: smaller;"><span style="font-family: Arial;">http://www.capacitors.hk/Varistor/TSVC.pdf</span></span></a></div><div>&nbsp;</div></div></div></div><p><img src="https://www.capacitor.com.hk/upload/Su-Suntan-SMD-Varistor-TSVC.jpg" alt="" title="" /></p>]]></description><category>Varistor</category><comments>https://www.capacitor.com.hk/capacitors/538.html#comment</comments><wfw:comment>https://www.capacitor.com.hk/</wfw:comment><wfw:commentRss>https://www.capacitor.com.hk/feed.asp?cmt=538</wfw:commentRss><trackback:ping>https://www.capacitor.com.hk/cmd.asp?act=tb&amp;id=538&amp;key=9e4e0981</trackback:ping></item><item><title>Как заказать Suntan TSV Ближний Варисторные</title><author>a@b.com (admin)</author><link>https://www.capacitor.com.hk/capacitors/528.html</link><pubDate>Fri, 02 Oct 2015 09:40:19 +0800</pubDate><guid>https://www.capacitor.com.hk/capacitors/528.html</guid><description><![CDATA[<p style="line-height: 19.2000007629395px;"><span style="font-size: smaller;"><span style="font-family: Arial;">Suntan Technology Company Limited</span></span><br /><span style="font-size: smaller;"><span style="font-family: Arial;">---All Kinds of Capacitors</span></span><span style="font-size: smaller;"><span style="font-family: Arial;"><br type="_moz" /></span></span></p><div style="line-height: 19.2000007629395px;"><table class="MsoNormalTable" border="0" cellspacing="0" cellpadding="0" width="491" style="width: 13cm;

The name is a portmanteau of variable resistor, which is misleading since it is not continuously user-variable like a potentiometer or rheostat, and is not a resistor but in fact a capacitor. Varistors are often used to protect circuits against excessive voltage by acting as a spark gap.<br />&nbsp;<br />After reading the introduction of ceramic disc capacitor, in order to help clients enhance understanding, here take a Suntan products for example .
