State of the Art, Inc. - Resistive Products

Quality | Product Levels

Standard Grade

Standard grade resistors are ideal for non-mission-critical applications. These products are designed for reliability and only differ from our military products in the screening performed. Our standard grade products are subject to DC resistance on a 100% basis, and solderability, temperature coefficient of resistance, and visual inspection on a sample basis during manufacturing. Standard grade resistors are not subject to any lot acceptance testing.

Military Grade

Our MIL-PRF-55342 chip resistors are subject to in-process inspections and Group A, B, and C lot acceptance testing. MIL-PRF-55342 resistors are maintained at s failure rate level on the basis of life testing. State of the Art, Inc. is listed on the QPL55342 (fixed chip resistors) for all product levels (M, P, R, S, U, V, and space level T) and all 13 slash sheets. Similarly, we are listed on QPL32159 (zero ohm chip resistors) for product levels M and space level T and all 13 slash sheets. We are also listed on QPL914 (surface mount resistor networks) for the / 03, / 04, and / 05 slash sheets.

High Reliability Grade

High reliability products are used in mission-critical applications where QPL products are not available or are not adequate. High reliability products include DLA Land and Maritime drawings, customer source control drawings, and our own test protocols based on MIL-PRF-55342 created for our customers’ convenience. Most of the high reliability screening we perform is based upon the lot acceptance testing of MIL-PRFF-55342.
