Film Cards

Smiths Interconnects 73 series High Frequency Film Cards are designed to offer accurate and repeatable dissipation of low Radio Frequency power signals. We offer a complete line of standard and custom wave-guide attenuator elements. Deposition of thin film metallization on a specific substrate with an optical grade finish produces an extremely stable resistive film. A protective coating is evaporated over the resistive film to prevent oxidation. Controlled processes throughout production ensure repeatability.
