Analyzing the property that electrical resistance increases as temperature rises.
PTC resin has the property of increasing electrical resistance as the temperature rises (temperature dependence). We conducted an analysis of a heater that utilizes this property. This heater has the characteristic that as the temperature rises, the inherent resistance of the PTC resin increases, limiting the current, so it does not exceed a certain temperature. We will perform a current distribution analysis when a voltage of 100[V] is applied to the electrode terminals of the heater. For more details, please download the catalog.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on a computer. In traditional design and development environments, the process has primarily revolved around trial and error through prototyping based on the experience of engineers and experiments with prototypes. However, conducting experiments using actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototyping-based approach to an analysis-based design approach will be a crucial challenge for improving productivity, and establishing simulation technology as the core of analysis-based design techniques will be essential. In this context, Photon is developing and providing "analysis software" focusing on electromagnetic fields, as well as heat, vibration, and sound fields. By utilizing Photon's software, efficient development and design of various industrial products can be achieved. In this way, Photon aims to support users in reducing the number of prototypes, lowering development costs, and shortening development periods in their manufacturing environments, ultimately enhancing their competitiveness.
