Littelfuse specializes in a broad offering of circuit protection products, including their NTC thermistor NXKE502M3T1NEC001. We’ve had some questions recently concerning a seeming discrepancy between this product’s listed part number and the part numbering given in its datasheet, which suggests that KX502J2 would be the correct part number. Is this a website or documentation error?
Fortunately, this isn’t an error at all. KX502J2 is an older/alternative name for this product, as confirmed by Littelfuse. The documentation for the series is a bit long in the tooth, though the electrical information for the product is still accurate.
