Resettable PPTC Datasheet Low Rho Series PolySwitch Resettable PPTC RoHS Description Littelfuse Low Rho Surface Mount PPTC (Polymer Positive Temperature Coefficient) devices provide overcurrent protection for applications where ultra low internal resistance, ultra low voltage drop and automatic resettable protection are desired. This new series allows a higher hold current device in a smaller factor and lower profile as compared to a standard PPTC. It offers ultra low internal resistance while maintaining the high level electrical characteristics and performances of standard PPTC products. All devices are UL recognized and TUV approved and have maximum fault current of 50A. They are available in 0402 to 2920 sizes while the hold current ranges from 100mA to 9A. Features & Benifits Ultra low internal resistance Compatible with high temperature solders Very thin profile Broadest range of Hold Additional Information Miniature size saves board Current ratings (100mA to 9A) space RoHS compliant, Lead Free Allows a higher hold current and Halogen Free dvice in a smaller factor and lower profile as compared to UL recognized and TUV a standard PPTC approved Fast response to fault Resources Accessories Samples currents Agency Approvals Applications Agency Agency File Number LCD / LED HDTV USB peripherals including new USB 3.0 / 2.0 ports Computer periperals E183209 Li-ion / Li-Polymer battery Digital cameras and video R50119118 packs cameras Smart phones Hard disk drives Tablet and Notebook PCs Game consoles E-readers WARNING Users shall independently assess the suitability of these devices for each of their applications Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such conditions are expected to be repetitive or prolonged in duration Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device. 2021 Littelfuse, Inc. 1 Specifications are subject to change without notice.
