"压敏电阻规格书.pdf" 压敏电阻，也称为金属氧化物变阻器（MOVs），是电子设备中广泛使用的过电压保护元件。这些电阻器具有非线性的伏安特性，即在正常工作电压下，其阻值很高，而在电压超过其阈值时，阻值会显著下降，从而能够分流过电压，保护电路免受损害。World Products Inc. 提供的压敏电阻经过了多项安全认证，包括UL、CSA和VDE，符合IEC61051-2标准，并且部分型号还满足ANSI/IEEE C62.11加速老化测试要求。此外，生产工厂通过了ISO和TS16949认证，确保了产品的高质量和一致性。这些压敏电阻符合EIA标准的带状包装，并具备良好的可焊性，符合MIL STD标准。对于环保要求，World Products Inc. 提供符合RoHS指令2002/95/EC的产品，其中(-N)后缀表示符合RoHS标准，对铅、汞、六价铬、多溴联苯(PBB)、多溴二苯醚(PBDE)以及镉的含量限制在极低水平。产品一致性通过极其严格的品质控制和统计过程得以保持，采用在线自动测试设备进行100%的检验。World Products Inc. 提供多种类型的压敏电阻，几乎涵盖了所有常见的金属氧化物变阻器类型，方便设计师准确选择和设计。这些电阻具有极低的漏电流水平和出色的浪涌处理能力，得益于专有的配方技术。在物理特性方面，环氧树脂的性能得到严格控制，确保了尺寸的一致性和焊接性的改善。World Products Inc. 的压敏电阻设计灵活，能够快速响应客户对于严格应用的需求。规格书中详细列出了各种系列的电气特性、尺寸、引脚修改选项以及峰值脉冲和降额曲线等信息，如DS系列、ES系列、VZ25RS系列、VZ32KW系列、VZ34单双系列、VZ40系列和VZ53系列等，为用户提供全面的技术参数参考。 World Products Inc. 的压敏电阻是设计者和工程师在保护电子设备免受过电压损害时的重要选择，其高性能、多样性和环保特性使其成为可靠的安全保障。
