Analyzing the property that the electrical resistance increases as the 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 intrinsic 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 computers. In traditional design and development environments, the process has primarily revolved around trial and error through prototypes based on the experience of engineers and experiments with those prototypes. However, conducting experiments with actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototype-based approach to an analysis-based design is a critical issue for improving productivity, and establishing simulation technology as the core of analysis-based design techniques is a challenge. 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 reduce the number of prototypes and development costs, shorten development periods in the manufacturing sites of our users, and ultimately support the enhancement of our users' competitiveness.
