MIL-PRF-55342-8 Resistors, Chip, Fixed, Film, Nonestablished Reliability, Established Reliability, Space Level, Style Rm2010This specification covers the requirements for style RM2010, fixed, film, chip, nonestablished reliability, established reliability, and space level resistors. This style is available in characteristic H, characteristic E, characteristic K, characteristic L, and characteristic M, resistance tolerances .1 percent, .25 percent, .5 percent, 1 percent, 2 percent, 5 percent, and 10 percent, and all termination materials. Designers are CAUTIONED on using these resistors in high power pulses applications \(see 6.5\).

6.4 Electrostatic charge effects. Under relatively low humidity conditions, some types of film resistors, particularly

those with small dimensions and high sheet resistivity materials, are prone to sudden significant changes in

resistance (usually reductions in value) and to changes in temperature coefficient of resistance as a result of

discharge of static charges built up on associated objects during handling, packaging, or shipping. Substitution of

more suitable implements and materials can help minimize this problem. For example, use of cotton gloves, static

eliminator devices, air humidifiers, and operator and workbench grounding systems can reduce static buildup during

handling. Means of alleviating static problems during shipment include elimination of loose packaging of resistors and

use of metal foil (conductive) and static dissipation packaging materials. Direct shipments to the government is

controlled by MIL-DTL-39032 which specifies a preventive packaging procedure.

6.5 Changes from previous issue. The margins of this specification are marked with asterisks to indicate where

changes from the previous issue were made. This was done as a convenience only and the Government assumes no

liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the

requirements of this document based on the entire content irrespective of the marginal notations and relationship to

the last previous issue.
