MIL-PRF-55365 Capacitor, Fixed, Electrolytic \(Tantalum\), Chip, Established Reliability, Nonestablished Reliability, And High Reliability, General Specification ForThis specification covers the general requirements for non-established reliability \(non-ER\), established reliability \(ER\), and high reliability tantalum dielectric, fixed chip capacitors, primarily intended for use in thick and thin film hybrid circuits or surface mount applications for filter, bypass, coupling, and other applications where the alternating current \(ac\) component is small compared to the direct current \(dc\) rated voltage and where supplemental moisture protection is available \(see 6.1\). The established reliability capacitors have reliability ratings established on the basis of life tests performed at specified voltage at +85??C for failure rate levels \(FRL\) ranging from: a. 1.0 percent per 1,000 hours to 0.001 percent per 1,000 hours in accordance with MIL-STD-690. These FRL?╞s are established at a 60-percent confidence level and are maintained at a 10-percent producer?╞s risk \(exponential distribution\). b. 0.1 percent per 1,000 hours to 0.001 percent per 1,000 hours or 1 FIT \(FIT = failure unit = one failure per 109 device hours\) at 90-percent confidence level \(Weibull distribution\).

3.26 Marking. Molded style capacitors shall be marked in accordance with method I of MIL-STD-1285, and shall

be as specified (see 3.1). Polarity marking shall be as specified (see 3.1). All styles shall have the following

information marked on the package.

a. "JAN" brand.

b. PIN.

c. Manufacturer's source code in accordance with MIL-STD-1285.

d. Lot date code.

e. Optional marking of lot identification number on individual capacitors.

3.26.1 "JAN" and "J" marking. The United Stated Government has adopted, and is exercising legitimate control

over the certification marks "JAN" and "J", respectively, to indicate that items so marked or identified are

manufactured to, and meet all the requirements of specifications. Accordingly, items acquired to, and meeting all of

the criteria specified herein and in applicable specifications shall bear the certification mark "JAN" except that items

too small to bear to certification mark "JAN" shall bear the letter "J". The "JAN" or "J" shall be placed immediately

before the part number except that if such location would place hardship on the manufacturer in connection with such

marking, the "JAN" or "J" may be located on the first line above or below the part number. Items furnished under

contracts or orders which either permit or require deviation from the conditions or requirements specified herein or in

applicable specifications shall not bear "JAN" or "J". In the event an item fails to meet the requirements of the

specification and the applicable specification sheets or associated specifications, the manufacturer shall remove

completely the military part number and the "JAN" or the "J" from the sample tested and also from all items

represented by the sample. The "JAN" or ""J" certification mark shall not be used on products acquired to contractor

drawings or specifications. The United States Government has obtained Certificate of Registration Number 504,860

for the certification mark "JAN" and Registration Number 1,586,261 for the certification mark "J".

3.26.2 Substitution of FRL and product levels. The manufacturer may substitute, with acquiring agency approval,

FRL and product levels in accordance with table V. If a manufacturer only utilizes Weibull grading, then product

manufactured to Weibull product levels B, C, or D may be marked as Exponential product levels M, P, R, or S and

supplied on the order.
