Ptc Resettable Fuses datasheet and documents for FRU250-30F
Ptc Resettable Fuses Overview
The FRU250-30F is a radial leaded PTC resettable fuse from the RFE/Fuzetec FRU series. It features a maximum voltage rating of 30V and a hold current (Ih) of 2.5A, with a trip current (It) of 5A. The component operates within a temperature range of -40°C to 85°C and can withstand peak currents up to 100A. Constructed with tin-plated copper clad steel leads (24 AWG), it provides overcurrent protection for electronic circuits.
Ptc Resettable Fuses Feature Summary
- Radial leaded construction suitable for through-hole mounting
- Solid-state polymer design for reliable circuit protection
- Low resistance characteristics for efficient power handling
Ptc Resettable Fuses Applications
- Up to 30VDC electronic equipment protection
- Wide variety of consumer electronics circuits
- Battery pack overcurrent safeguarding
Ptc Resettable Fuses Procurement Notes
Verify the manufacturer designation as RFE/Fuzetec when sourcing components. Confirm that the specific part number FRU250-30F matches the required 30V and 2.5A specifications. Ensure the radial lead configuration aligns with the target PCB layout requirements before finalizing procurement orders.
Ptc Resettable Fuses Selection Notes
Select this component for applications requiring 30VDC maximum voltage and 2.5A continuous hold current. The 5A trip current threshold defines the overcurrent activation point. Consider the -40°C to 85°C operating range for environmental compatibility. The radial lead style dictates the physical mounting orientation on the printed circuit board.
Ptc Resettable Fuses Part Context
This device belongs to the FRU series of radial leaded PPTC fuses manufactured by RFE/Fuzetec. The series offers various current ratings within the 30V limit. The FRU250-30F specifically addresses mid-range current protection needs using a robust polymer positive temperature coefficient material for reversible circuit interruption.
Ptc Resettable Fuses Replacement Considerations
Compatible substitutes include other radial PTC fuses with matching 30V and 2.5A ratings, such as the FRU185-30F or FRU300-30F, provided the trip current and package dimensions are verified against the original design constraints.
