Littelfuse Expands PolySwitch® Low Rho SMD Series Adding 23 New Ratings to The Existing Product Portfolio
CHICAGO, December 8, 2020 - LITTELFUSE, Inc. (NASDAQ: LFUS), a global manufacturer of leading technologies in circuit protection, power control and sensing, today announced an additional 23 new ratings in the PolySwitch® Low Rho SMD series of PPTC devices. The new ratings are available with a lower resistance of 1mOhm, hold currents from 0.75 A to 9.0 A, a maximum voltage from 6.0 V to 24 V all in surface mountable sizes from 0402 to 2920. These additions make the Low Rho SMD series the broadest PPTC portfolio currently available on the market.
The PolySwitch Low Rho SMD Resettable PPTCs provide robust overcurrent protection for electronics applications where ultra-low internal resistance, ultra-low voltage drop and automatic resettable protection are desired.
Typical markets and applications for the Low Rho Resettable PPTCs include:
* Consumer electronics
* Mobile and wearables
* Servers and computing equipment
* Portable medical devices
* USB Type A and Type B ports
* Lithium batteries
"Our expanded Low Rho SMD Resettable PPTCs portfolio includes a much broader array of both ratings and sizes," said Stephen Li, Global Product Manager at Littelfuse. "This provides electronics engineers with greater design flexibility, especially when developing the next generation of battery protection and charging ports for consumer electronics applications."
PolySwitch Low Rho SMD Resettable PPTCs offer these key benefits:
* Less power dissipation resulting from ultra-low internal resistance.
* Fits compact designs where PCB space is very limited via surface mount sizes from 0402 to 2920 and very thin profile.
* Aids compliance with industry standards via UL and TUV certifications.
* Environmentally friendly components are RoHS compliant, lead free and halogen free.

【经验】如何为汽车线束过流保护选择一款合适的PPTC保护器件？
为提升汽车线束的过流防护能力，需要加入一款车规级PPTC保护器件，本文通过以12V工作电压、导线截面积为0.35mm2线束为例，推荐littelfuse的AHRF系列16V PolySwitch汽车用高温无铅径向引线型自恢复PPTC，型号为AHRF750，保持电流7.5A，动作电流为14.8A，最大工作电压16VDC，可满足设计需求。
【经验】可恢复保险丝（PPTC）在光模块测试设备应用中的注意事项和选型推荐
在光模块测试设备设计时，需要可恢复保险丝PPTC，对整个测试设备进行保护作用。主要注意：选择贴片的保险丝，设计方便；选择工作时的最高直流电压，在这个设备中，最好选择12V或者以上；在保险丝下方尽量铺地来散热，防止PPTC无限制升温；注意在工作温度下的I-Hold电流。选择的PPTC一定要注意在70-80℃。建议选择littelfuse的2920L700/12。
