Vishay推出新款径向固定IHVR电感器，节省空间，提高DC/DC转换器能效

<p><em>10 mm x 6.4 mm x 10 mm封装，径向固定配置，减小占位面积，直流内阻低至0.130 mW，工作温度达+155 °C</em></p>

<p>日前，Vishay Intertechnology, Inc.（NYSE：VSH）宣布，<a name="_Hlk84945915">推出</a>10.25 mm x 6.4 mm x 10 mm 4025外形尺寸新型IHVR径向固定电感器---<a href="http://www.vishay.com/ppg?34575">IHVR-4025JZ-3Z</a&gt;。<a name="_Hlk84945947"></a>Vishay Dale <a href="http://www.vishay.com/ppg?34575">IHVR-4025JZ-3Z</a&gt;采用全新设计，优化电感，减小直流内阻（DCR），提高DC/DC转换器效率，工作温度高达+155 °C，适用于计算机、服务器、通信和工业应用。<o:p></o:p><o:p>&nbsp;</o:p></p>

<p>与传统电感器相比，<a name="_Hlk84945938">日前发布的器件体积小，采用独特的径向固定设计，节省电路板空间，可利用气流提高冷却效率，同时直流内阻减小</a>50 %至0.130 mW（典型值），额定电流高达112 A。相对于低效解决方案，新款器件直流内阻低可显著节省服务器整个生命周期的能源成本。此外，其矩形形状可以更好地与其他电路板元器件搭配，便于设计人员保持电路板迹线长度相等，减少相位失衡。<o:p></o:p></p>

<p>IHVR-4025JZ-3Z特别适合用于DC/DC 转换器储能，频率最高可达5 MHz，以及电感器自谐振频率（SRF）以下大电流滤波。器件应用包括台式电脑和服务器、薄型多相大电流电源、负载点（POL）转换器、分布式电源系统和FPGA。这些应用中，电感器的电感量和饱和电流在-40 °C至+155 °C整个工作温度范围内非常稳定。<o:p></o:p></p>

<p>IHVR-4025JZ-3Z采用100 %无铅（Pb）屏蔽复合结构，噪声降至非常低的水平，具有高抗热冲击、耐潮湿、抗机械振动能力，可无饱和处理高瞬变电流尖峰。器件符合RoHS和<a href="http://www.vishay.com/doc?99912">Vishay绿色</a>标准，无卤素。<o:p></o:p></p>
