Discoidal Capacitors

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.

Discoidal Part Numbering System
After determining the capacitor properties required for
a given application, use information from pages AC4-7
and the part numbering system below to place the order.
If there are any questions, do not hesitate to contact
API’s customer service.
Example: 340055AX145P6B0

The part number shown represents a discoidal with
an outer diameter of 0.340" and inner diameter of 0.055".
The voltage rating for this part is 50 VDC. The ceramic
type will be X7R. The capacitance value is 1,400,000 pF
with a tolerance of +100, -0%. The termination will be
silver and the parts will receive bulk packaging. Since
the last identifier in the part number is “0”, there are
no special requirements.
