One “FE lot”is composed of several wafers issued from the same thin film deposition sequence. • The date code named Batch Number(BN). The “BN” is defined after completion of the end of production testing sequence. The lot homogeneity is given by the “FE lot” and not by the “BN”. According to the applied rules validated by the ESCC through the product qualification, the following situations are agreed: • Parts coming from different “FE lost” might have the same “BN”. • A maximum of two different “BN” might be applied to the same “FE lot” to enable the use of overruns from a previous PO. • Unless requested / approved by the customer the “BN” will be 2 years old maximum. SPECIFIC TRACEABILITY REQUIREMENTS The following specific requirements have to be treated as: • A customer who requires “Lot Homogeneity” has to mention it on the PO as “SINGLE PRODUCTION LOT”. • A customer who requires “Lot Homogeneity” in addition to a “Single Batch Number” has to mention it on the PO as “SINGLE PRODUCTION LOT AND OPTION R0101”. END OF PRODUCTION TESTING Mandatory testing performed at the end of the production process: • 100 % overload: Voltage 6.25 P n x R n or 2 UL whichever is less - duration 2 s • 100 % burn in: 168 h at Pn at 70 °C Revision: 19-Nov-14 Document Number: 53043 3 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.

When lot validation testing is required, it shall consist of the performance of one or more of the tests or subgroup test sequences of chart F4 indicated in the ESA Generic Specification ESCC 4001. The testing to be performed and the sample size shall be as stipulated in the purchase order. When procurement of more than one component type is involved from a family, range or series, the selection of representative samples shall also be stipulated in the purchase order.

When the component is too small to accommodate all of the marking specified, as much as space permits shall be marked and the marking information, in full, shall accompany each component in its primary package. The information to be marked and the order of precedence, shall be as follows: • Rated Resistance (for variants 01 to 21); Terminal identification and array reference code (for variants 22 to 42) (see Physical Dimensions and Terminal Identification) • The ESCC qualified components symbol (for ESCC qualified components only) • The ESCC component number • Traceability information Terminal identification shall be by means of the location of the marking. Due to the size of the component only the 4 digit resistance value code or array reference code, as applicable (see the ESCC component number), shall be marked on the component. For symmetrical marking using reversible figures such as 0, 6 or 9, the first resistor of the array, R1, shall be identified by a dot. For arrays with 2 or 3 resistors, the marking shall be located adjacent to the first 2 resistors of the array. The first resistor, R1, of the array is the upper resistor whilst reading the marking, as follows: 4 67 5 13 6 1 2 3 Resistor 1 Resistor 2 Resistor 3 Resistor 1 1 13 4 Resistor 2 2 67 5 Resistor 3 3 6 For arrays with 4 to 8 resistors, the marking shall be located adjacent to the first 4 resistors of the array. The first resistor, R1, of the array is on the left hand end of the array whilst reading the marking, as follows: 12 11 10 9 5 0 0 2 1 2 3 Resistor 1 Resistor 2 Resistor 3 8 7 4 5 6 Resistor 4 Resistor 5 Resistor 6 PERFORMANCE TESTS Overload Climatic sequences Thermal shock Load life Resistance to solder heat CONDITIONS CECC REQUIREMENTS DRIFTS ABSOLUTE PER (TYPICAL VALUES) RATIO 2.5 Un/2 s 0.05 % Rn + 0.05 0.01 % Rn -55 °C to +155 °C/5 moisture cycles 0.1 % Rn + 0.05 0.01 % Rn -55 °C to +155 °C/5 cycles 30' 0.05 % Rn + 0.05 0.01 % Rn 1000 h/Pn at +70 °C 0.1 % Rn + 0.05 0.02 % Rn 2000 h 0.15 % Rn + 0.05 260 °C/10 s 0.05 % Rn + 0.05 0.01 % Rn Moisture resistance 0.01 Pn at 40 °C 93 % RH 0.1 % Rn + 0.05 0.01 % Rn High temperature storage 1000 h/no load at +155 °C 0.1 % Rn + 0.05 0.02 % Rn Note • Rn: Nominal resistance Revision: 19-Nov-14 Document Number: 53043 6 For technical questions, contact: [email protected] THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
