PolySwitch Resettable PPTCs Surface Mount > microSMD Series RoHS microSMD Series Description The microSMD series provides surface mount overcurrent protection for applications where space is at a premium and resettable protection is desired. Features Broadest range of resettable devices available in industry Low resistance Small 1210 footprint Fast time-to-trip RoHS complaint, lead-free and halogen-free Agency Approvals Applications AGENCY AGENCY FILE NUMBER Mobile Electronics and Batteries E74889 Computer Telephone and broadband 78165 Portable electronics Automotive Multimedia Industrial controls 72161779 Game machines Battery Additional Information Datasheet Resources Samples Electrical Characteristics I I V I P Max Time-to-trip R R H T MAX MAX D MAX MIN 1MAX Part Number (A) (A) (V ) (A) (W) (A) (s) () () DC microSMD Series Size 3225mm/1210mils microSMD005F 0.05 0.15 30 10 1.00 0.25 1.50 3.60 50.00 microSMD010F 0.10 0.25 30 10 0.80 0.50 1.00 2.10 15.00 microSMD035F 0.35 0.75 6 40 0.80 8.00 0.20 0.32 1.30 microSMD050F 0.50 1.00 13.2 40 0.80 8.00 0.05 0.25 0.90 microSMD075F 0.75 1.50 6 40 0.80 8.00 0.10 0.11 0.40 microSMD110F 1.10 2.20 6 40 0.80 8.00 0.20 0.07 0.21 microSMD150F 1.50 3.00 6 40 0.80 8.00 1.00 0.04 0.11 microSMD175F 1.75 3.50 6 40 0.80 8.00 0.80 0.025 0.08 microSMD200F 2.00 4.00 6 100 0.80 8.00 2.50 0.020 0.06 Notes: I : Hold current: maximum current device will pass without interruption in 20C still air. H I : Trip current: minimum current that will switch the device from low resistance to high resistance in 20C still air. T V : Maximum continuous voltage device can withstand without damage at rated current. MAX I : Maximum fault current device can withstand without damage at rated voltage. MAX P : Power dissipated from device when in the tripped state in 20C still air. D R : Minimum resistance of device as supplied at 20C unless otherwise specified. MIN R : Maximum resistance measured one hour post-trip or post-reflow at 20C. 1MAX 2019 Littelfuse, Inc. Specifications are subject to change without notice.
