Data Sheet FTP Series FTP Series PTC Thermistor "Micro Heater" (Flat Thin head Insulated Type) FTP Series Applications Features Self-Temperature Control by PTC characteristics. Heating Electric Device for Temperature compensation Low voltage operation Removal of dew condensation or freeze Top surface insulated SMD part Compact light design Fastest time heating operation Small spot heating Paper dryer for PPC printer Design free heating layout Several Accessory warmer (Camera, Mirror etc.) Beauty and Health-Care application (Massager etc.) Overview The FTP series generate heat at specified temperature when voltage is applied and also serve to control temperature. The FTP series are mounted PTC ceramics, so high reliability and quick heating up are available. Also outer size is small, so the FTP series can heat required small part only. And electricity loss can be minimized as for heating. In addition to the above, the FTP series can be operated with low voltage battery. These help the customer downsize heating construction and high performance. Attention: This datasheet is downloaded from the website of Murata Manufacturing Co., Ltd.
