  专为满足电动汽车(EV)系统的独特需求而设计,828和827系列提供10kA的断流额定值、宽工作温度范围(-55°C~125°C)以及多种安装选项,包括通孔安装和螺栓固定版本。这些特性使其成为车载充电器(OBC)和配电单元(PDU)的理想选择,满足其对高压、高可靠性和紧凑型设计等关键应用场景的需求。

  核心差异化优势:

  · 额定电压:828系列为1,000VDC;827系列为800VDC;

  · 断流能力:两系列均在额定电压下达到10kA;

  · 安装灵活性:提供通孔安装和螺栓固定版本,集成ISO端子及间隔引线;

  · 标准合规性:符合AEC-Q200、RoHS、无卤素及100%无铅要求。

  该系列保险丝无需额外安装配件或复杂引线成型工艺,既简化了高压电路集成流程,又最大化提升了PCB空间利用率,其可靠结构确保在恶劣环境中保持性能与耐久性,对电动汽车应用至关重要。

  “828/827系列保险丝以更小尺寸提供亟需的高压保护,符合AEC-Q200标准,填补了汽车电子领域高直流电压保护的空白。”Littelfuse全球产品经理Style Liu表示,“其紧凑型设计与灵活安装选项让工程师能够自由优化布局,同时确保保护性能不受影响。”

  828和827系列扩展了Littelfuse面向快速发展的电动出行市场的电路保护解决方案产品组合。通过将高额定电压与汽车级可靠性及灵活组装选项相结合,该系列保险丝助力设计工程师开发出更安全高效的电动汽车动力系统。

  目标应用:

  · 汽车电子设备;

  · 车载充电器(OBC);

  · 配电单元(PDU);

  · 高压电动汽车子系统。
