Ptc Resettable Fuses datasheet and documents for SRP200F
Ptc Resettable Fuses Overview
The Littelfuse SRP200F is a PolySwitch resettable PPTC fuse designed for strap mount installation. It features a hold current of 2 A and a trip current of 4.4 A, with a maximum voltage rating of 30 VDC. The device has a resistance of 100 mOhms and a rated fault current of 100 A. Physical dimensions are 23.4 mm in length, 11 mm in width, and 1.1 mm in height. It operates within a temperature range of -40°C to +85°C and dissipates up to 1.6 W.
Ptc Resettable Fuses Feature Summary
- Provides overcurrent protection by raising resistance as it heats to limit current flow
- Designed for strap mount installation on printed circuit boards
- Acts as a solid-state resettable fuse to protect circuits from shorts and overcurrent events
Ptc Resettable Fuses Applications
- Protection of rechargeable batteries from overcurrent, short circuits, and overcharging
- Overcurrent protection for automotive actuators, screens, and small motors
- Circuit protection for wiring harnesses and PCB components
Ptc Resettable Fuses Procurement Notes
Verify the specific Littelfuse datasheet for the SRP200F to confirm RoHS compliance status and detailed environmental ratings. Ensure the selected component matches the required strap mount form factor and that the electrical parameters align with the target circuit's voltage and current specifications before finalizing procurement.
Ptc Resettable Fuses Selection Notes
Select this component when a low-profile, strap-mounted resettable fuse is required for battery or low-voltage circuit protection. The 2 A hold current and 30 VDC rating suit applications needing compact overcurrent defense. Consider the 100 mOhms resistance for minimal power loss in steady-state operation.
Ptc Resettable Fuses Part Context
The SRP200F belongs to the SRP series of PolySwitch resettable fuses manufactured by Littelfuse. This series includes various form factors such as surface-mount, radial-leaded, and battery-strap devices. These components are engineered to provide reliable overcurrent protection across automotive, telecom, and general power supply applications.
Ptc Resettable Fuses Replacement Considerations
Public confirmed substitute part numbers include D83524-000, RF2254-000, and RF1675-000. Verify compatibility with existing mounting constraints and electrical requirements when substituting.
