SUMMARY

The discussion centers on identifying inrush current limiting devices, specifically a component marked with a double-V logo, which is associated with Littelfuse. Participants suggest that the component may be a PTC (resettable fuse) and reference a transient voltage suppression (TVS) diode. The part number "TS250-130F-RA-N-2" from Littelfuse is highlighted as a potential match. Users are encouraged to utilize Google Images for further identification.

PREREQUISITES
  • Understanding of inrush current limiting devices
  • Familiarity with PTC (resettable fuses)
  • Knowledge of transient voltage suppression (TVS) diodes
  • Experience with component identification techniques
NEXT STEPS
  • Research Littelfuse products, specifically the TS250-130F-RA-N-2
  • Learn about the function and application of PTC resettable fuses
  • Explore transient voltage suppression (TVS) diode specifications and uses
  • Investigate techniques for identifying electronic components through image searches
USEFUL FOR

Electronics engineers, circuit designers, and technicians involved in troubleshooting and identifying electronic components, particularly those working with inrush current limiting devices.

TL;DR
Help me recognize these inrush current limiting devices
I have a circuit board, and one of these inrush current limiting devices (yellow arrows) has failed. Does anyone recognize them? Failing that, does anyone recognize the logo that looks like a letter V and an upside down V superimposed? I have searched in several places, but have been unable to identify them.

Perhaps clamping diode ie a TVS ( transient voltage suppression ) .
the 103 could mean 1000 watts but that's a guess.
