Hello,
the LTC4011 charger uses an 10k NTC to measure battery temperature.
https://www.analog.com/media/en/technical-documentation/data-sheets/4011fb.pdf
Datasheet page 17: "The LTC4011 is designed to work best with a 5% 10K NTC thermistor with a β near 3750, such as the Siemens/EPCOS B57620C103J062."
I could not find this NTC thermistor. However I found the following device from EPCOS/TDK: "B57620C5103J062"

The part number is very similar. Does the part number in the datasheet contain a typo?
Thanks.
Daniel
Hi Daniel,
It is possible that this is a typo or that the product was obsolete or updated. I am not sure. However, the specs of the B57620C5103J062 is compliant to the specs stated in the datasheet. I think you can use this part.
