【产品】Littelfuse扩展PolySwitch低Rho SMD系列自恢复PPTC，电阻低至1mΩ
2020年12月8日，全球领先的电路保护、电源控制和传感技术制造商LITTELFUSE宣布，PolySwitch®低Rho SMD系列PPTC器件中额外增加23个新等级。新等级产品的电阻更低，为1mOhm，保持电流范围为0.75 A~9.0 A，最大电压从6.0 V至24 V不等，其表面安装尺寸为0402至2920。这些新增产品使低Rho SMD系列成为目前市面上最广泛的PPTC产品组合。
PolySwitch低Rho SMD自恢复PPTC为需要超低内部电阻、超低压降和自动自恢复保护的电子应用提供强大的过流保护。
低Rho自恢复PPTC的典型市场和应用包括：
•消费电子产品
•移动和可穿戴设备
•服务器和计算设备
•便携式医疗设备
•USB Type A和Type B端口
•锂电池
Littelfuse全球产品经理Stephen Li表示：“我们经过扩展的低Rho SMD自恢复PPTC产品组合包括更广泛的额定值和尺寸范围。 这为电子工程师提供了更大的设计灵活性，尤其是在为消费电子产品应用开发下一代电池保护和充电端口方面。”
PolySwitch低Rho SMD自恢复PPTC具有以下主要优势：
•内阻极低，从而降低了功耗。
•0402至2920的表面安装尺寸和超薄设计适合PCB空间有限的紧凑型设计。
•UL和TUV认证有助于符合行业标准。
•环保组件符合RoHS标准、无铅且无卤素。
