PTC Resettable Fuses

PPTCresettable fuse18122.00 A12 VDCsurface mount

JK-mSMD200-12 is a 2.00 A hold-current, 12 VDC 1812 PPTC resettable fuse for low-voltage surface-mount overcurrent protection.

Best for

  • Low-voltage DC overcurrent protection
  • Compact 1812 surface-mount designs

Avoid if

  • The circuit voltage can exceed 12 VDC
  • Repeated or prolonged fault conditions are expected

Check before use

  • Derate the 2.00 A hold current for the actual ambient temperature.
  • Confirm transient voltage, fault energy, and PCB thermal conditions.
  • Use the recommended reflow process; the device is not intended for bottom-side wave soldering.
