Ohio Semitronics Inc.

Ohio Semitronics Inc., doing business as OSI, is a for-profit manufacturer of specialized electronic components headquartered in Hilliard, Ohio that supplies power measurement technologies, transducers, converters, transformers, cable assemblies, and related defense electronics to the Department of Defense as a prime contractor on purchase orders and indefinite-delivery vehicles, predominantly under total small business set-asides.

OSI competes almost exclusively in the small-business set-aside space. Of 587 total awards in the source data spanning four decades, 100% are prime contracts; the vendor carries just one recorded sub-award, a January 2026 calibration task from Fluor Marine Propulsion on Naval Nuclear Laboratory work. The company holds no GWACs, BPAs on government-wide vehicles, or agency-wide IDIQs; instead, its footprint consists entirely of single-award, small-business-set-aside indefinite-delivery contracts and firm-fixed-price purchase orders issued by individual Defense Logistics Agency and Army commands. Recent IDCs include a $350,000 DLA Land and Maritime small-business set-aside for ammeters (awarded April 2026), a $350,000 DLA Aviation small-business set-aside for motional transducers (awarded February 2026), and a $101,250 Army Materiel Command Redstone small-business set-aside for AC transducers supporting the Force Provider containerized-kitchen program at Letterkenny Army Depot (awarded January 2026, through January 2031). Earlier vehicles include a $250,000 DLA Land and Maritime power-transformer IDC (May 2022 through May 2023) and a $39,283 Army Contracting Command Redstone AC-transducer IDC (January 2023 through January 2026, with three delivery orders totaling $16,579 obligated as of June 2025).

Customer concentration is heavily skewed toward DLA. The top five customer agencies account for 85% of awards by count: Defense Logistics Agency Land and Maritime leads with 191 awards and $3.1 million combined potential value, followed by DLA Aviation with 160 awards and $1.9 million, Naval Supply Systems Command with 80 awards and $794 thousand, Naval Sea Systems Command with 44 awards and $621 thousand, and the broader DLA with 25 awards and $100 thousand. By potential-value ranking, Army Materiel Command Contracting Command Detroit Arsenal ranks second despite fewer awards (7 awards), carrying $2.3 million potential value—a signal of larger individual orders through that command. The Office of Naval Research holds eight awards valued at $1.3 million combined.

Activity has been consistent over the past five years but shows recent decline: the vendor received 35 awards in 2022, 37 in 2023, 27 in 2024, 26 in 2025, and 9 awards in the first four months of 2026 (source dated July 15, 2026). Combined potential value across all awards totals $11.2 million, with $8.3 million obligated (75% realization). The vendor's award portfolio spans 587 discrete transactions dating back to 1981, indicating long-standing DoD supplier status. Recent purchase-order awards cluster in the $1,400 to $30,000 range for individual electronic components—motional transducers, waveform converters, current transducers, power transformers, relays, ammeters, power supplies, circuit card assemblies, and cable assemblies—with delivery performance concentrated at OSI's Hilliard facility and distribution to DLA depots and military installations across CONUS and OCONUS locations.

Award concentration by NAICS reflects the manufacturing footprint: Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals leads at 134 awards, followed by Other Measuring and Controlling Device Manufacturing (66 awards), Other Metal Container Manufacturing (47 awards), Power, Distribution, and Specialty Transformer Manufacturing (35 awards), and Capacitor/Resistor/Coil/Transformer Manufacturing (32 awards). PSC codes align similarly: Electrical and Electronic Properties Measuring and Testing Instruments (161 awards), Combination and Miscellaneous Instruments (142 awards), Coils and Transformers (62 awards), and Miscellaneous Electrical and Electronic Components (60 awards). The vendor's capability set centers on power measurement instrumentation and precision electronic components for military aviation, land, maritime, and communications platforms—a specialized, high-frequency ordering posture characteristic of DLA's transactional supply chain for field replacement parts and equipment sustainment.

OSI offers Measurement Products for virtually any AC/DC single or polyphase application. Our equipment can measure the following parameters: Voltage, Current, Watts, Watt-hours, VAR, VAR Hours, VA, Power Factor, Phase Angle, Frequency and Demand.
