UNSPSC 32121902: Ceramic resonator

UNSPSC 32121902 Ceramic resonator is a Commodity code that covers electrical components and parts used in utility protection systems, industrial control infrastructure, and facility maintenance—grounded in recent state and local solicitations that emphasize protection relays, electrical components for SCADA systems, motor control centers, and distributed electrical parts procurement. The code sees activity across utility authorities, county governments, school districts, and transit authorities. Kissimmee Utility Authority (Florida) solicited SEL 451 and SEL 751 protection relays under a sole-source RFQ due August 24, 2026, requiring equipment fully compatible with existing SCADA infrastructure and protection schemes. Hillsborough County Board of County Commissioners (Florida) issued ITB-26-00277 for ongoing Schneider brand electrical components (estimated $519,787 over two years) to be used in SCADA control panels, with bids due June 18, 2026. Northside Independent School District (San Antonio, Texas) posted IFB2026118 for electronic equipment, parts, repairs, rentals, and services with responses due September 24, 2026. Trinity Metro (Tarrant County, Texas) established an IDIQ contract for electrical materials used in maintenance, repair, and emergency operations across transit facilities, with proposals due August 20, 2026. Gwinnett County Parks and Recreation (Georgia) requested annual contract quotes for ballasts and capacitors (approximately 200 units annually of each) due June 12, 2026.

Recent activity concentrates in Florida, Texas, and Georgia. The Hillsborough County and Kissimmee Utility Authority procurements in Florida represent the most substantial recent volume, with standardized component specifications and multi-year contract terms. The code shows strong activity from utility authorities and county infrastructure departments procuring replacement components and standardized electrical parts for aging protection systems and control infrastructure. Geographic spread includes the Southeast (Florida, Georgia) and Texas, with secondary activity across other state and local systems requiring electrical components for water, utility, transit, and facility maintenance operations.
