Networks fit for high reliability
applications
Established-reliability surface-mount chip resistor networks are now available from State of the Art qualified to MIL-PRF-914.
Established-reliability surface-mount chip resistor networks are now available from State of the Art (SOTA) qualified to MIL-PRF-914 (revision G, amendment 3) These SOTA resistor networks are designed for use in mission-critical applications such as manned space flight, life support systems, human-implantable medical devices, and prolonged periods in satellite communications The networks are available in two JEDEC QPL style sizes

High-reliability for chip resistors
State of the Art (SOTA) is expanding its line of established high-reliability chip resistors qualified to MIL-PRF 55342 (revision G, amendment 3).
RNS030 (/03) measures 0.30 x 0.30 x 0.05in and has a power rating of 800mW.
RNS040 (/04) measures 0.350 x 0.350 x 0.05in and has a power rating of 1W.
SOTA also offers a SLAMDIP QPL style network resistor, RNS050 (/05), which measures 0.410 x 0.150 x 0.03in and has a power rating of 800mW.
All three styles have a temperature characteristic of 300ppm (Product Level M) or 100ppm (Product Level K), and a maximum voltage rating of 50V.
The SOTA MIL-914 networks are available with standard resistance values from 10ohm to 2.2Mohm and standard tolerances of 10, 5, 2 and 1%.
Network termination consists of a high-adhesion conductive base layer covered by a nickel barrier to prevent solder joint degradation.
The outer finish is fused 60/40 tin/lead solder.
The MIL-PRF-914 resistors are available in two product level categories, determined by the extent of product testing.
Level M is an "established reliability" product that requires ongoing life tests with failure rates established at just 1% per 1kh.
In addition, all Level M parts are subjected to 100h power conditioning.
These networks are tested for use in extreme environmental conditions.
The operating temperature range for the resistors is -55 to +125C.
Level C is a "non-established reliability" product manufactured with the same design and process as the Level M product, but not subjected to the same degree of testing.
While SOTA's considerable experience and rigid quality control at its ISO9001 manufacturing facility assure reliable operation, additional high-reliability screening can be provided to meet the most stringent applications.
Pricing starts at $3.00 each in production quantities.
Delivery is from stock in 9 weeks.
