Ohmite TFA Series Fixed Thin Film Attenuators
Ohmite TFA Series Fixed Thin Film Attenuators are designed with thin-film technology and integrate the attenuation circuit into a single chip. These attenuators are designed using the electrodes and resistance patterns formed on a ceramic substrate. The epoxy-based material on the resistive film protects the resistance, and the electrodes are plated on the exterior. The Fixed Thin Film Precision Chip Attenuators feature a wide frequency range of DC to 20GHz and an operating temperature range of -40°C to 125°C. The TFA series is available in three popular sizes, 0603, 0805, and 1206.
