Temperature limitation of each components surface
If you need to calculate more in detail to choose suitable a far for your application, please refer to information below.
・ Please address specific temperature range of each component.
・ Please test under worst case conditions.
・ The lower the input voltage is, the more heat tends to generate.
・ Please ensure a Type K thermocouple is securely attached and anchored during temperature measurement.
・ Please measure under no air flow conditions and at highest temperature spot throughout a range of temperatures to ensure
stable operation.
