Mica Capacitors

SHARMA Mica Capacitors have been designed to meet the exacting physical, electrical and environmental requirements of the MIL-C-5, R-153 and the current RoHS specifications. Careful selection of raw materials, starting with the finest grade of Ruby Mica, and the constant monitoring of all equipment and processes, provides an overall uniform level of quality consistent with today's most sophisticated electronic equipment ideal for Tuning, Timing, Filtering and Coupling Circuits.

FEATURES

• Low Loss and high stability

• Available in very close tolerances

• Suitable for precision applications

• Wide range of operating temperature

GENERAL SPECIFICATIONS:

CAPACITANCE RANGE: 1pF to 82,000pF

VOLTAGE RATING: 50V DC TO 500V DC (Higher voltage capacitors can also be custom made)

TEMPERATURE RATING: -40 to +150⁰C

CASE SIZES: DM05 to DM42

INSULATION RESISTANCE: 100,000 M Ohms minimum at 25⁰C for capacitance up to 10,000pF. Please refer to characteristic curve for values above the range.

DISSIPATION FACTOR: <0.1% at 1 M Hz for values between 100 to 1,000pF; <0.2 at 1 K Hz for values above 1,000pF. Please refer to characteristic curve for values above the range.

LIFE TEST DETAILS:

Capacitors shall withstand 1.5 times the rated DC voltage at 125⁰C for 2000 hours. After the test:

1. Capacitance change shall not exceed 1% of the initial value or 1pF, which ever is greater.

2. Dissipation Factor shall be within 1.5 times the original limits.

3. Insulation Resistance shall meet the initial specified requirements.

4. There shall be no remarkable change in the appearance and the marking shall remain legible.
