Frequently Asked Questions
When is MF-SM030-2-99 preferable to a one-time chip fuse?
Use it when a circuit benefits from resettable PTC protection; the device is rated for 1.7 W dissipation and can recover after many temporary overload conditions.
Which resistance range should designers consider during normal operation?
The available specs list a 0.9 to 4.8 ohm resistance range at 23 °C, which should be checked against voltage-drop and load-current limits.
How should procurement treat lifecycle risk for this Bourns part?
Because the part is marked obsolete, buyers should verify remaining tape-and-reel inventory, 2-pin footprint compatibility, and approved alternates before committing production demand.
