1. Photoconductive Cells CdS

Photosensitive devices can be divided into photovoltaic devices, photoemissive devices. CdS cell is a type of photoconductive devices. These are semiconductor sensors that utilize the photoconductive effect in which light entering the photoconductive ...

2. Interchangeable NTC Thermistors

3. NTC THERMISTORS

Thermistors are temperature sensitive passive semiconductors which exhibit a large change in electrical resistance when subjected to a relatively minute change in body temperature.
NTC (Negative Temperature Coefficient) thermistors decrease ...

4. Varistors

SEN Varistors are voltage dependent, nonlinear devices which have an electrical behavior similar to back-to-back zener diodes.
The symmetrical, sharp breakdown characteristics enable the varistor impedance changes many orders of magnitude from ...
