If you have observed varying degrees of indentations on the leads (as shown below) of NTCLE203E3222SB0 NTC Thermistor from Vishay
please note that we have clarified this with the manufacturer, and according to them, these indentations do not affect the functionality or reliability of the product.
Please see their response below.
The indentation detected in this lot is a tooling imprint in the wire to form the leadwires ‘bayonet’ as we call it, in order to fit the ceramic thickness in-between the two leadwires to assure that the plane of the leadwires is within certain degrees of the plane of the ceramic surface. Without it, the sensor head will mechanically turn more depending on the R-value in the NTCLE203 series.
As there are natural variations in the raw material of the leadwires, some wire lot’s have a bit more ‘spring’ effect and need to be formed more into the plastic zone, leaving more imprint of the tooling onto the leadwires.
These indentations have no effect on the functionality nor reliability of the product. These tooling imprints are imperative and will show up from time to time a bit more or a bit less.
