TMP302: TMP302 with conformal coating affects accuracy?

Part Number: TMP302

Hi, 

May I know if we have analysis done on TMP302 with conformal coating? Do we have any concern on the accuracy impact after conformal coating?

Thanks,

Christina

    Hi Christina,

    In general, conformal coating should not affect accuracy on a temperature sensor device. 

    On the temperature + humidity devices(HDC302x, etc), conformal coating is not recommended due to the open cavity in the device.  TMP302 does not have such an open cavity and conformal coating will not affect accuracy.
