121-503JAJ-Q01 Product Details

121-503JAJ-Q01 Overview


NTC thermistors are packaged as a Bulk. The Cylindrical Probe, Glass package contains it for your convenience. In order for NTC thermistors to operate, the resistance tolerance must be ±20%. When using NTC thermistors, the temperature should be set to -60°C~300°C to ensure reliable operation. Total number of terminations on these NTC thermometers is 2. To make an NTC thermistor work properly, it needs to have the 2 pins connected.
