Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'F/33' against official Littelfuse documentation to confirm the 33VDC rating and variant specifications. Ensure compatibility with AEC-Q200 requirements for your target application. Cross-reference the Mouser number 576-AHS120F/33-2 or manufacturer part number AHS120F/33-2 for accurate sourcing. Confirm RoHS compliance status via the latest datasheet before procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a 1.2A hold current and 33VDC maximum voltage are required for automotive circuits. The 2018 package size offers a compact footprint for space-constrained designs. Consider the 150mOhms initial resistance for power loss calculations. Ensure the operating environment stays within the -40°C to +125°C range. Verify that the 2.3A trip current aligns with the protected circuit's normal operating limits.

Ptc Resettable Fuses Part Context

This device belongs to the Littelfuse AHS series of automotive-grade PolySwitch resettable fuses. These components are engineered to protect sensitive electronics from overcurrent events by raising resistance as they heat. The series includes various hold currents and voltage ratings to suit different automotive subsystems, providing reliable, reusable protection compared to traditional one-time fuses.
