Part Number: BQ4050

In BQ4050 datsheet, NTC recommendation is a Mitsubishi BN35-3H103 with a B factor value of 3486K.

My cell pack is equiped with a Semitec 103AT-4 10K Ohm NTC with a B factor value of 3435K.

Is there an issue on the B value delta ?

Hi Gilles

You should be fine with the Semitec. That is the thermistor we typically use for the default config for mode for most of our gauges.
Pls test out the temperature measurement to verify

THANKS
