Thermik Specification
特密
Power class PTC thermistors
Series PTC thermistors
Installation
The PTC’s are usually installed parallel to the coil so that the mechanical strain is minimized. The Mylar-Nomex shrink cap is well suited due to its mechanical stability (no cold flow, as opposed to Tefl on). In conjunction with the miniature pill (Ø 1,5 mm), response times of ≤ 5 seconds to a maximum of 10 seconds were achieved.
Function
Thermik thermistors correspond to DIN 4408, DIN 44082 and IEC 34-11-2, and exhibit a very high temperature sensitivity. The resistance increases strongly in the area of the rated response temperature. This change can be used to switch off the load circuit through a triggering device. Electronic evaluations of many different applications are also possible. The typical characteristics of Thermik thermistors are presented in the temperature resistance diagram.
