Additional Details

The B57620C224J62V2 has a base resistance of 220 kΩ at 25°C, and its resistance changes inversely with temperature. The B value (also known as the thermal sensitivity index) indicates the rate of change in resistance with temperature. A higher B value indicates a greater change in resistance for a given temperature change, which can lead to improved sensitivity in temperature measurement. The tolerance on the resistance at 25°C specifies the allowable variation in the resistance value, directly affecting the accuracy of temperature measurements. Refer to the official EPCOS/TDK datasheet for precise specifications, including the exact operating temperature range, power dissipation constant, and other crucial parameters for accurate application.
