Hello cebil.eapen,

It appears that it may be part of the [468 series](https://www.digikey.com/en/products/filter/fuses/139?s=N4IgjCBcoGwJxVAYygMwIYBsDOBTANCAPZQDaIALAAxwDMdIAuoQA4AuUIAymwE4CWAOwDmIAL6EwcABwJoIFJAw4CxMiCpMJIALQAmRAqh8ArqpKRyCRtp1zkx3mcIXyEG4R0VDi5XhfqYACsenDeNmJiQA) from Littelfuse. They do provide some specifications on the [datasheet](https://www.littelfuse.com/assetdocs/fuse-468-datasheet?assetguid=6b7857dc-f79c-4aae-8bcc-a9ef11ddef09) that may help identifying which current rating you would require.

@nick_13812 is on the right track with the Littelfuse 468 series.

From the 468 series datasheet:

So, it is the 0.500mA version:

- [0468.500NRHF](https://www.digikey.com/en/products/detail/littelfuse-inc/0468-500NRHF/2023655)

@cebil.eapen

@David_1528 did link the part number at the bottom of the post, it would link to our web-page for that item to order.

Again, the part number is:

- 0468.500NRHF
