High purity Alumina Substrate
Thermo-sensitive thermistor
Ni alloy thin-film resistive elements
100% matte tin finish terminations
(RoHS compliant and Pb Free)
Features:
1206 English case size
100mW power rating

High volume production suitable for
commercial and special applications
The ATV1206C series of temperature variable attenuators utilizes a thermo-sensitive thermistor to control attenuation
change over temperature. These are useful in replacing temperature compensation circuits and can simplify auto gain
control (AGC) and circuit design in power amplification devices resulting in reduced design time and cost savings.
