Rhopoint is proud to be an authorised partner to Ametherm, bringing our customers a range of thermistors suited to a vast array of applications and industries.
There are two types of thermistors (thermally-sensitive resistors), Negative Temperature Coefficient (NTC) and Positive Temperature Coefficient (PTC). The difference is that NTC thermistors exhibit a DECREASE in resistance as body temperature increases, while PTC thermistors exhibit an INCREASE in resistance as body temperature increases.
Our thermistors are built to be rugged, reliable and stable. They are equipped to handle extreme environmental conditions and noise immunity more so than other types of temperature sensors.
Inrush Current Limiters are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power-up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.
Additionally, devices that produce alternating currents such as electric motors or transformers can draw several times their steady-state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60-hertz cycle, that is enough time to cause possible damage to the equipment.
It can sometimes be hard to find exactly what you need. If you are struggling to locate the parts you are looking for, or would like some advice on what to select, talk to one of our friendly advisors who will be happy to help. Find out now!
