• Protection for peripheral interfaces and data lines

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix '-2' corresponds to the required packaging configuration, such as cut tape or reel options, as indicated by distributor part numbers like TSV250-184F-2TR-ND. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 1) requirements against your manufacturing process specifications before finalizing orders.

Ptc Resettable Fuses Selection Notes

Select this component when a low initial resistance of approximately 3 Ohms is required for minimal signal attenuation. Ensure the circuit's normal operating current remains below the 184 mA hold threshold. Verify that the available space accommodates the 2-SMD footprint dimensions of 8.95mm x 7.40mm.

Ptc Resettable Fuses Part Context

This device belongs to the TS Series of PolySwitch resettable fuses, which are characterized by fast time-to-trip performance. The series offers sorted and matched resistance options to ensure consistency across production batches. These components serve as reusable alternatives to traditional one-time fusible links in modern electronics.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same family include TSV250-184F without the trailing suffix, depending on packaging needs. Cross-reference with TSL250 variants if through-hole mounting is acceptable instead of surface mount.
