CONSTRUCTION
Extended foil
LIFE TEST
Capacitors can withstand a test potential of rated voltage at 85°C between terminals for a period of 2,000 hours, with not more than one failure per group of 18 tested. Failure is defined as permanent short or open circuit.
HUMIDITY RESISTANCE
Exceeds requirements of MIL-STD-202, Method 103.
HIGH FREQUENCY VIBRATION
Capacitors meet the 2000 cycle test in accordance with Method 204 of MIL-STD-202A, condition B. Vibration is continuous for a four hour period in each of two directions, parallel and perpendicular to the major axis.
Test results show no mechanical damage, and no evidence of intermittent contacts or open short circuiting.
QUALITY CONTROL
Capacitors are 100% tested for:
 |
CAPACITANCE TOLERANCE |
|
DISSIPATION FACTOR |
|
DIELECTRIC WITHSTANDING VOLTAGE |
|
INSULATION RESISTANCE |
Complete process and inspection data is maintained on file and is available on special request.
|
MARKING
All capacitors are marked with one or more of the following: company initials "EC", corporate logo or EC trademark -- in addition to type MP88 or PT88, capacitance, tolerance, rated DC working voltage and date code.
DATE CODE
The first two digits of the date code represent the year, the second two digits the week, i.e., 9952 is the 52nd week of 1999, 0102 is the second week of 2001.
QUALITY ASSURANCE
Major emphasis is placed on quality assurance. Raw material inspection and the use of SPC manufacturing procedures assure the highest quality standards. Procedures are fully described in the EC Quality Control Manual. Electronic Concepts, Inc. will continue to advance the state-of-the-art by utilizing leading edge technology, ultra-miniature capacitor designs and establishing reliability procedures.
In constructing the components described, the full intent of the specification will be met. Electronic Concepts, Inc. does however, reserve the right to depart from detail specifications in order to improve the design of its products. Components made under military approvals will be done so in accordance with specification requirements.
This information is believed to be accurate and reliable, However, Electronic Concepts, Inc. assumes no responsibility for its use, nor for any infringement of patents or other rights of third parties which may result. |
