Copal's E-TA Series Thermal Variable Attenuators

E-TA series are ideally suited for high-frequency signals

Image of Copal Electronics' E-TA Series Thermal Variable Attenuators  Copal Electronics' E-TA series thermal variable attenuator is a miniature, low-cost, surface-mount attenuator available in standard 2.0 mm x 1.25 mm x 0.9 mm (E-TA2012) or optional 3.2 mm x 1.6 mm x 0.9 mm (E-TA3216) case sizes. The E-TA series is manufactured with Copal's unique thermistor materials and LTCC (Low Temperature Co-fired Ceramics) technology for compatibility with high-speed wireless communications. The inverse characteristics of this thermal variable attenuator compensate for the change of output caused by temperature change. Eight types of temperature coefficient characteristics (N1~N8) are available for the E-TA2012 series, and four types (N5~N8) are available for the E-TA3216 series. These wide variety of temperature coefficient types make it easier to select the temperature coefficient needed in the compensation circuit when compared to other temperature compensation methods.
