38、 CODE IDENT NO. 037Z3 DWG NO. 09002 REV PAGE 8 6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime from a day to years after manufacture and can develop under typical op
39、erating conditions, on products that use such materials. Conformal coatings applied over top of a whisker-prone surface will not prevent the formation of tin whiskers. Alloys of 3 percent lead, by mass, have shown to inhibit the growth of tin whiskers. For additional information on this matter, refe
40、r to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 Low tolerance resistors. In low tolerance resistors (.005 and .01), resistance shifts due to high humidity are normal to precision, fixed, resistors. Before being considered out of tolerance, resistors should be condit
41、ioned in a dry oven at +125oC for 1 hour, +15 minutes, -0 minutes followed by 2 hours, +30 minutes, -0 minutes stabilization at ambient temperature before measurement. Resistors which continue to be out of tolerance after the above conditioning process are considered rejects. 6.5 Electrostatic charg
42、e. Under several combinations of conditions, these resistors can be electrically damaged, by electrostatic charges, and drift from specified value. Users should consider this phenomena when ordering or shipping resistors. Direct shipment to the Government is controlled by MIL-DTL-39032 which specifi
43、es a preventive packaging procedure. 6.6 Pulse applications. Designers are CAUTIONED on using these resistors in high power pulse applications. Since they have not been qualified nor tested for such applications. These resistors only see a one time pulse (Overload) as part of the group B inspection
44、of this specification. These resistors are subject to damage and premature failures when they see excessive pulsing. 6.7 User of record.
