PTC Resettable fuse applicationguidelines
To select or specify the most suitable PTC resettable fuse for yourapplication, Eaton recommends a 6-step process:
1. Determine your circuit’s parameters - note your normaloperating current, max operating voltage, max interrupt current,maximum ambient temperature.
2. Select a PTC resettable fuse - based on the maximum ambienttemperature and steady-state current. Use thermal derating graphs/charts.
3. Compare ratings - use an electrical characteristics table, comparethe selected device’s maximum ratings with your circuit’s maximumratings.
4. Determine time-to-trip - use defined maximum time-to-tripand/or available time-to-trip curves if available.
5. Verify your operating temperature range - confirm desiredperformance in application operating temperatures.
6. Verify fuse dimensions and mounting style - for pad layoutdimensions or lead dimensions and suitability in end product design.
Final notes
A PTC resettable fuse is a protection device only intended to operateduring overcurrent and/or overtemperature events that are not normaloperation and are generally undesired conditions. They are not intendedto be a switch that operates numerous times in normal operation.Treating PTC fuses as switches can cause them to fatigue if cycled toomany times or held in a tripped position for extended periods of time.Also, a resettable PTC fuse is not a one-time fuse (or positive one-timedisconnect). There still is a small amount of residual current that flowsthrough the PTC when in a tripped position where a one-time fuse isa one-time disconnect that is designed to permanently open during anovercurrent event.
