Semitec NTC thermistors and thermistor sensors provide high accuracy temperature sensing and control for electronic and programmable thermostats.  Semitec command dominant market shares in the electronic thermometer market, e-vehicle, office automation and mobile telecom battery packs.  They are also becoming the temperature sensor of choice in the medical device market in applications such as blood glucose monitoring, catheters and other wearable medical devices.

Yageo Nexensos are the world leaders in thin-film platinum sensor technology and are the inventors of platinum sensing elements.  Widely adopted by industry, thin film platinum elements are now mass produced and have found their way into numerous automotive (EGR sensor), commercial (electronic thermostat) and appliance (pyrolytic oven) applications.  Heraeus can also integrate platinum sensors with a heating element onto a single ceramic chip for applications such as e-cigarettes and low mass air-flow sensors.

PEPI thermal cut-outs, SEKI thermal cut-outs and Asahi thermostats offer cost-effective temperature control or over-temperature protection whereas Matsuo’s long-life precision thermostats bridge the gap between electronic temperature controllers and simple bimetallic mechanical thermostats.

SEFUSE thermal fusesTKS PTC thermistors and Semifuse PTC fuses provide reliable circuit protection in rechargeable batteries and fire panels.   Constant current is supplied via Semitec CRD current limiting diodes and current surges are controlled by SCK inrush current limiters.  Voltage spikes and surges are suppressed by TVR series varistors and GDT series gas discharge tubes.

Campini adjustable thermostats provide accurate room temperature control and help provide a comfortable living environment.  They are also used to control small cooking appliances and commercial trouser presses.

We pride ourselves on providing you with a high level of customer service and excellent in-depth technical knowledge, from your initial call to our knowledgeable technical sales team, through to dispatch and delivery from our friendly and efficient customer service team.
