U.S. Resistor product offering
Product offeringCore offering
U.S. Resistor manufactures custom, non-inductive ceramic and organic composition resistors in multiple form factors — axial lead, tubular, rod, disc, washer, slug/sleeve — plus pre-stacked resistor assemblies. All units are made to order (no stocking) in a 32,500 sq. ft. plant in St. Marys, PA, using proprietary sintered Zirconium Silicate (83-series) or Alumina (85-series) ceramic matrices for high-power, high-energy surge, and high-voltage industrial applications. Typical lead time is 2-4 weeks, with engineering consultation and volume discounts available for recurring orders.
Product overview
U.S. Resistor is a manufacturer of Non-inductive, Special Purpose, and Industrial Resistors. The product portfolio centers on ceramic and organic resistor materials manufactured from specially prepared powders. The core product line includes Axial Lead Resistors, Tubular Resistors, Rod Resistors, Disc Resistors, and Resistor Washers—each available in multiple form factors, sizes, and material compositions (Zirconium Silicate-based ceramic, Alumina-based ceramic, and organic). These products can be combined into Resistor Assemblies through stacking, and complemented by Slugs & Sleeves and various Available Terminals. The resistors serve high-power and high-energy surge applications including energy transmission and distribution systems, wind power systems, circuit breakers, surge protection, load banks, automotive ignition systems, and lightning arrestors.

U.S. Resistor competitors and assessment
Company assessmentBroad incumbents
- TT Electronics: TT Electronics manufactures a wide range of electronic components, including power resistors, for industrial, aerospace, defense, and medical markets. Its power-resistor and sensor portfolios overlap U.S. Resistor's customer base, though TT operates across many product categories at much greater scale.
- Vishay Intertechnology, Inc. Vishay is one of the world's largest manufacturers of passive electronic components, including a broad portfolio of resistors, inductors, and capacitors. While Vishay covers many of the same end-use segments as U.S. Resistor, it operates at massive scale across thousands of part numbers rather than specializing in custom HV composition resistors.
- KOA Speer Electronics: KOA Speer is a major manufacturer of passive components including chip, through-hole, and power resistors, serving automotive, industrial, and consumer markets. It competes with U.S. Resistor at the broader resistor category level but lacks the custom HV composition specialization.
Direct peers
- Ohmite Manufacturing Company: Ohmite is a long-established U.S. specialty resistor manufacturer focused on high-power, high-voltage, and custom resistive components for industrial, military, and aerospace markets. It is one of the closest direct competitors to U.S. Resistor in terms of product category, customer segments, and custom/high-voltage specialization.
- Riedon Company: Riedon manufactures precision and power resistors, shunts, and custom resistive solutions for industrial, medical, and aerospace customers. Like U.S. Resistor, Riedon emphasizes custom/specialty manufacturing and serves high-reliability segments with engineer-to-order engagement.
- HVR Advanced (Cebi): HVR Advanced (formerly HVR International) specializes in high-voltage resistors, including composition-type and ceramic-based designs, for power electronics, medical imaging, and industrial applications. The product overlap in high-voltage non-inductive resistors is nearly identical to U.S. Resistor's.
- Stackpole Electronics, Inc. Stackpole Electronics manufactures a broad line of resistive components including chip, through-hole, and power resistors. U.S. Resistor originated as Stackpole Corporation's Special Purpose Resistor Division before the 1992 divestiture, making Stackpole a direct lineage peer with overlapping product categories and customer types.
- Caddock Electronics, Inc. Caddock Electronics manufactures high-performance film and composition resistors for demanding applications including HV, high-pulse, and precision instrumentation. Its product positioning around specialty/high-reliability resistors directly overlaps U.S. Resistor's niche in industrial and high-energy applications.
