Discoidal Capacitors Ceramic discoidal feed-through capacitors are the building blocks of the EMI filter industry. API’s Spectrum Control discoidal capacitors provide great versatility in meeting varied voltage, capacitance and dimensional requirements. Our nonpolar, multilayer capacitors are small, reliable and high in dielectric strength. Operational temperatures of –55°C to +125°C are achieved with no voltage de-rating. The versatile nature of our discoidals makes them ideally suited for by-pass and filtering applications. Due to their low inductance construction, these capacitors perform extremely well in high frequency applications. The circular geometry of a discoidal feed-through capacitor offers many paths to ground, resulting in lower impedance and better filtering performance. The low profile and rugged design of our discoidal capacitors offer an excellent alternative to ceramic tubes. Multilayer Discoidal O.D. Ceramic dielectric Electrodes I.D.
