POLYSWITCH® Resettable PTCs Surface Mount > LoRho Series LoRho SMD PTC for Charging Cable Protection Description The Littelfuse LoRho SMD PTC for Charging Cables provides protection from heat generated due to faults within the connector such as USB-C, microUSB, and many others. As connectors get smaller, their pin-to-pin spacings are shrinking which increases the opportunity for debris such as dust, dirt, or water to collect causing a fault. These faults can generate heat which may damage charg.

POLYSWITCH® Resettable PTCs Surface Mount > LoRho Series LoRho SMD PTC for Charging Cable Protection Description The Littelfuse LoRho SMD PTC for Charging Cables provides protection from heat generated due to faults within the connector such as USB-C, microUSB, and many others. As connectors get smaller, their pin-to-pin spacings are shrinking which increases the opportunity for debris such as dust, dirt, or water to collect causing a fault. These faults can generate heat which may damage charging cables, the devices they charge, or the people using them. Agency Approvals AGENCY AGENCY FILE NUMBER AMPERE RANGE E74889* 4.5A J 50313999* 4.5A * See Electrical Characteristic Table for approved part numbers. Applications • Over temperature (OT) protection for USB connectors and cables including: – USB Type-C – USB Micro-B – USB-A • Fast charging standards and protocols including: – USB Power Delivery (PD) † – Qualcomm Quick Charge (QC) † – Mediatek Pump Express (PE) † – Samsung Adaptive Fast Charging (AFC) † – Huawei/HiSilicon Fast Charging Protocol (FCP) † † These charging protocols are the property of their respective owners.

Ihold = Hold current: maximum current device will pass without tripping in 20°C still air 2. Vmax = Maximum voltage device can withstand without damage at rated current (Imax) 3. Pd = Power dissipated from device when in the tripped state at 20°C still air 4. Rmin = Minimum resistance of device in initial (un-soldered) state 5. R1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow Soldering of 260°C for 20 seconds (Values specified were determined using PCBs with 0.115in x 1.0in ounce copper traces) Caution: Operation beyond the specified rating may result in damage and possible arcing and flame TCO and Pd Testing Method: Thermal Cut-Off Test– 1. Put the device into the thermostatic chamber controlled at room temperature or 25°C. 2. Apply the specified current to the device, and increase the chamber temperature at the rate of 2°C per minute. 3. Measure the device ambient temperature when the applied current has reduced to less than 20% of initial value. Power Dissipation– 1. Conduct thermal cut-off test at rated current/voltage. 2. After device trip, decrease the chamber temperature with keeping trip state. 3. Measure the tripped-state power dissipation when the device ambient temperature has reduced to 30°C or less. © 2019 Littelfuse, Inc. Specifications are subject to change without notice.
