Vishay / Barry Industries A Series High-Power Flanged Attenuators
Vishay / Barry Industries A Series High-Power Flanged Attenuators feature a high 250W input power rating and flanged mounting capability. The attenuators provide a covered resistive element, and some models have a symmetrical design. The A series offers two resistor construction types: thick film on BeO and thick film on AlN. The Vishay / Barry Industries A Series High-Power Flanged Attenuators are RoHS compliant and operate within a 1dB to 30dB nominal attenuation range.
