Audience Auricap and Auricap XO Specifications







CONSTRUCTION: Auricap metalized polypropylene capacitors are available only in extended foil
(non-inductive) construction.

PACKAGING: Polyester tape wrap with epoxy end fills gives the best possible volume density for this
type unit.

LEADS: Auricap leads are of polished, stranded High Purity Oxygen Free Copper with XLPE insulation.
Auricap XO leads use stranded OHNO (mono crystal) leads with XLPE insulation.
Auricap-R (R version) use non-insulated solid tinned copper leads.

TEMPERATURE RANGE: May be operated at rated DC voltage from -55C to +85C or to +105C at
voltages indicated by the derating curve on the applications page.


1. Capacitance shall be measured at or referred to 1000Hz +20Hz at 25C +5C for capacitance values up to
and including 1.0MF Capacitance values greater than 1.0MF shall be measured at 60Hz +6Hz.

Ref: MIL-STD-202E, Method 305.

2. Dissipation factor shall be measured as described for capacitance and shall not exceed 0.2%. Typical values,
throughout temperature range, any given on curves on the Auricap Application page.

3. Insulation resistance shall be measured at rated voltage or 500VDC whichever less. After 2 minutes
electrification, minimum values shall be 200,000 meg/MF, need not exceed 400,000 megohms

Ref: MIL-STD-202E, Method 302.

4. Dielectric Strength: Capacitors shall withstand specified DC test potential for 60 seconds through a limiting
resistance of 1 ohm/volt.

Terminal to terminal- 150% of DC rating.

Terminal to case- 200% of DC rating.

Ref: MIL-STD-202E, Method 301.

5. Dielectric Absorption: Dielectric absorption shall not exceed 0.1% when tested to MIL-C-19978D.

Ref: MIL-C-19978D. Paragraph 3.22.

6. Tolerance: 10% (unless otherwise noted)


1. Vibration: Capacitors will meet or exceed the requirements of MIL-STD-202E, Method 204C.

2 Moisture Resistance: Capacitors will meet of exceed the requirements of MIL-STD-202E, Method 103B,

Condition B, with 500V or rate voltage applied, whichever is less.

3. Life Test: Will withstand 140% of rated DC voltage for 250 hours at 105C, No more than 1 failure in 12 units
permitted when tested..

4. Lead Pull Test: The leads on these capacitors shall withstand a steady axially applied pull of 5lbs. For one
