TDFZ 170229, TDFZ 170279, TDFZ 170311 www.vishay.com Vishay Draloric RF Power Pot Capacitors for Coupling Purposes, Class 1 Ceramic Dielectric FEATURES The ceramic capacitor is housed in a rugged silver plated copper case. This construction allows additional “Beltcontacting” of the outer electrode terminal over the copper can shaft. The results are short conduction paths with low impedance and low inductance as well as protection of the outer electrode. APPLICATIONS Filter, bypass and coupling circuits were high voltage ratings are required. CAPACITANCE RANGE 2.0 nF to 4.0 nF QUICK REFERENCE DATA DESCRIPTION VALUE Ceramic Class 1 Ceramic Dielectric CAPACITANCE TOLERANCE ± 10 % R85 Type TDFZ 170229 TDFZ 170279 TDFZ 170311 Voltage (Vp) 40 000 25 000 32 000 Min. Capacitance (pF) 2000 5000 3000 Max. Capacitance (pF) 2000 5000 4000 Mounting Screw terminal MATERIAL Capacitor elements made from class 1 ceramic dielectric with noble metal electrodes. Connection terminals of the inner electrode and the case which covers the outer electrode terminal made from copper / brass, silver plated. FINISH The ceramic capacitor element is housed in a rugged silver-plated copper case. The electrical terminations are made directly to the noble metal electrodes utilizing special soldering techniques. This method of attachment provides a strong, rigid connection of unsurpassed reliability. The TDFZ types feature an umbrella-shaped coating rim made from silicone elastomer to minimize the adverse effects of moisture, dust and other impurities in the working environment and to improve the characteristics of the electrical field.
