1) IMPORTANT! MIL-PRF-55182 has inactivated for new design characteristics C and E (hermetic styles) when used in conjunction with terminal type C (solderable/weldable) only. Characteristics C and E can still be procured with terminal type R (solderable) and type N (weldable). Similarly, MIL-PRF-55182 has inactivated characteristics H, J, and K (non-hermetic styles) when used in conjunction with terminal type R. Characteristics H, J, and K can still be procured with terminal type C and type N.
** Hermetic resistors (Characteristics C and E) for the MIL-PRF-55182 styles listed in the NPSL are currently only available from Angstrohm. Previously, Vamistor was a qualified source, but they have dropped their QPL status and are no longer supplying the resistor styles covered in this section of the NPSL.
2) Space Level Product: MIL-PRF-55182 includes a Space Level Quality option designated by the letter "T" in the failure rate level character of the part number. "T" level product receives additional screening and inspection at the manufacturer prior to delivery. This inspection includes additional testing beyond the basic requirements, specifically
3) For RNC90Y resistors any resistance value may be ordered within the ranges listed in the selection list tables. However, it is preferred that resistance values be selected from the standard decade values shown in the listings herein.
4) RNC90Y resistors should ONLY be used in applications where their particular characteristics of
