MIL-PRF-914-4 Resistor Network, Fixed, Film, Surface Mount, 20-Pin, Leadless Chip Carrier, Nonestablished Reliability And Established Reliability, Style Rns040This specification covers the detail requirements for RNS040 resistor networks. Resistors covered by this specification are considered a monolithic design or wire bond and die construction. The established reliability \(ER\) and nonestablished reliability \(non-ER\) styles are available in all characteristics and resistance tolerances. Designers are CAUTIONED on using these resistors in pulse applications \(see 6.6\).
