Expansive Lineup of PTCC Devices Gains 23 New Ratings

Dec. 10, 2020
The resettable PPTCs provide robust overcurrent protection for applications in consumer electronics, mobiles, wearables, and portable batteries.

Twenty-three new ratings have been added to Littelfuse’s PolySwitch Low Rho SMD series of polymeric positive temperature coefficient (PPTC) devices. The new ratings are available with a lower resistance of 1 mΩ, hold currents from 0.75 A to 9.0 A, and a maximum voltage from 6.0 V to 24 V, all in surface mountable sizes from 0402 to 2920.

The 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 applications are found in consumer electronics, mobile and wearable devices, servers and computing equipment, portable medical devices, USB ports, and lithium batteries.

Key benefits of these PPTC devices include lower power dissipation resulting from ultra-low internal resistance. They fit into compact designs where PCB space is very limited. They will also aid in complying with industry standards via UL and TUV certifications.

The Low Rho PPTC series is available in tape and reel format. Sample requests can be placed through authorized Littelfuse distributors worldwide.
