Current Sense Amplifiers (1/2): Why not to use an OpAmp (CMRR etc.)
Issues with high side sensing, common mode voltage and CMRR … ↓↓↓ Complete description, time index and links below ↓↓↓ First I have a look at a typical high side current sensing application using an OpAmp in differential amplifier configuration. There is also a short excursion why low side current sensing is easier but might not ...

This is an NTC 47D-15 thermistor, commonly used for inrush current limiting and temperature sensing applications. The code 47D-15 represents: 47 → Nominal resistance of 47 ohms at 25°C D → Disc-type thermistor 15 → Diameter of 15mm As temperature increases, its resistance decreases, making it useful for overcurrent protection, temperature compensation, and thermal monitoring in various electronic circuits. #NTCThermistor #TemperatureSensor #Electronics #InrushCurrentLimiter #ThermalProtection #R
