Overview
The Panasonic ERT-J1VR103J is a high-precision NTC thermistor designed for accurate temperature sensing in demanding electronic systems. Its 10kΩ resistance at 25°C and a tight B25/85 value of 4300K ensure reliable thermal feedback. A critical design consideration for this component is managing self-heating effects; while its 100mW power rating is adequate for many applications, engineers must account for the power dissipated by the measurement current, which can introduce inaccuracies in environments with poor thermal dissipation or when operating near the upper temperature limit.
Key Features
