A temperature sensor with the features of "ultra-compact," "high-speed response," and "non-contact." It is ideal for medical, healthcare, and wearable devices.
<Thermometer> ●ET-3H Achieves a more compact design than conventional products! It is characterized by a very small measurement error due to the high-precision classification of thermistor characteristics. ●FT-ZM A unique product from SEMITEC! Created through the thin-film technology of thermistors that is not available from other companies! The features of the thin-film thermistor "FT series," which are "thin" and "compact," allow for surface contact with the measurement part, achieving a 70% increase in response speed compared to the conventional "ET-3H." <Catheter> ●Fμ Sensor Offering ultra-small sensors with diameters of 0.5 mm and 0.3 mm! This is a compact and high-precision thermistor sensor created through thin-film technology and microfabrication technology. The development of the thin-film thermistor Fμ series not only achieves miniaturization but also incorporates trimming technology to ensure uniform thermistor characteristics, providing high precision (characteristic tolerance ±0.3%). This product has a proven track record in medical (catheter) applications. <Ear Thermometer> ●Thermopile It can detect infrared radiation emitted from the eardrum, allowing for non-contact body temperature measurement! It is used in "ear thermometers" and also in forehead thermometers commonly seen during the COVID-19 pandemic.

Company information
SEMITEC Corporation is a manufacturer of thermistor elements, thermistor sensors, and surge absorbers. Its features include a rich variety of thermistor elements in its lineup and the ability to provide thermistor sensors that are processed into optimal shapes for specific applications. The company has a proven track record of adoption across a wide range of fields and applications, including medical, office automation, home appliances, automotive, and industrial machinery. Additionally, SEMITEC Corporation manufactures and sells thermistors known as "FT Thermistors," which are produced using a unique thin-film technology that combines traditional ceramics manufacturing methods with semiconductor technology. This proprietary thin-film technology enables miniaturization, fast response, and high heat resistance, and these thermistors have already been adopted as standard sensors in copiers and printers, as well as in various sensors for catheters and thermometers. For global expansion, the company has manufacturing bases in Japan, South Korea, the Philippines, Vietnam, and India, with two locations in China. Its sales offices are located in Japan, China, Taiwan, South Korea, Thailand, and the United States, allowing for rapid product supply. *The company changed its name from Ishizuka Electronics Co., Ltd. in March 2011.
