My Vishay NTC Curve

""My Vishay NTC Curve" provides a resistance-temperature table for many NTC thermistors available from Vishay. This free tool can be downloaded to any computer, where the Excel® macro VBA file must be saved without any name modification. If you are not able or allowed to use macro enabled Excel® files, we suggest you to use the online NTC RT Calculation Tool.

User Instructions

4. Indicate a directory where the generated R-T files will be saved. This location can be changed when the file is re-opened.
5. You are now ready to compute R-T curves. The program records all the files that are generated and saves their names and location in a list available in the program.
6. If you enter an incorrect part number, the program will allow you to start the operation again, or you will be given the option to request that the curve be emailed to you from Vishay. Just follow the on-screen prompts.
