Use

It is used to protect electrical circuits from overcurrent and short circuit conditions by limiting the flow of current in the event of a fault.

Characteristics

  • Resettable: Can return to its normal state after the fault condition is removed.
  • Self-protecting: Eliminates the need for replacement after a fault.
  • Compact size: Suitable for various electronic applications.
  • Fast response time: Provides quick protection against overcurrent events.

Package

The MF-R090-0-99 is typically available in tape and reel packaging for automated assembly processes.

Essence

The essence of the MF-R090-0-99 lies in its ability to provide reliable overcurrent protection while offering the convenience of a resettable device.

Packaging/Quantity

It is commonly packaged in reels with quantities varying based on the manufacturer's specifications.

Specifications

  • Hold Current: 0.9A
  • Trip Current: 1.8A
  • Voltage Rating: 60V
