What Electro Technik Industries does

Electro Technik Industries (ETI) is a privately held U.S. holding company founded in 1981 and headquartered in Clearwater, Florida, that manages a portfolio of 15+ wholly-owned subsidiaries specializing in the design and manufacture of passive electronic components. The company organizes its operating companies into three primary business units: capacitive and resistive products (Arizona Capacitors, Plastic Capacitors, Precision Resistor Company, Hymeg, Tepro/Vamistor, Custom Suppression), RF and microwave components (Nova Microwave, Res-Net Microwave, RF Techniques, Southern Microwave, Star Microwave), and magnetics and transformers (Raycom Electronics, Hytronics, Inductive Technologies). ETI's product portfolio spans metalized plastic film capacitors rated up to 200 kVDC, wire wound and thick film resistors, ferrite-based circulators and isolators for frequencies up to 40 GHz, custom transformers qualified to MIL-PRF-27 and MIL-STD-1553, and pulse forming capacitor networks.

The company generates revenue primarily through direct hardware sales of these passive components to defense contractors, military end-users, aerospace OEMs, and a secondary mix of medical, telecom, power conversion, industrial, and instrumentation customers. Pricing is quote-based and tied to custom specifications, with multi-year contract cadences typical for defense and aerospace work. Distribution is hybrid: direct sales for large defense/aerospace custom programs, complemented by an authorized distributor network (Richardson Electronics, New Yorker Electronics, NAC Semi, M-TRON, World Micro) for standard products and international distributors (Tactron, YE-International, Melcom Electronics) for European and Russian/CIS RF customers. ETI's competitive positioning rests on domestic U.S. manufacturing across five states, ISO 9001:2015 certification, 35+ DoD cage codes, and an extensive MIL-spec qualification portfolio (MIL-PRF-27, MIL-STD-1553, MIL-STD-202, MIL-STD-790, NASA NPC 200-3).

Recent strategic activity has been acquisition-driven (RF Techniques in 2019, Precision Resistor Company in 2021, Southern Microwave and Advanced Conversion in 2023), supplemented by a European sales office in Arcachon, France (2022), a co-development partnership with W.L. Gore for 200°C high-temperature capacitors (2025), and the launch of the HP Drive Test Kit for 800V+ SiC e-mobility inverters in partnership with Peak Nano Systems (2026). Leadership includes Stéphane Mitrani (CEO and Board Member) and Darryl Mayo (President). Revenue is not publicly disclosed.

Core offering

Electro Technik Industries designs and manufactures passive electronic components — including capacitors, resistors, magnetics, and RF/microwave components — through a portfolio of 15+ wholly-owned subsidiary companies. Products are sold as both standard catalog items and custom-engineered solutions across voltages up to 200 kVDC, frequencies up to 40 GHz, and operating temperatures up to 200°C for defense, aerospace, medical, telecom, industrial, and instrumentation markets.

Product overview

Electro Technik Industries (ETI) operates as a parent company managing multiple passive electronic component manufacturers organized into three primary business units: capacitive/resistive products, microwave/RF products, and magnetics/transformer products. The company does not offer a single unified product but rather a portfolio of subsidiary companies each specializing in distinct product lines. The capacitive portfolio includes Arizona Capacitors and Plastic Capacitors offering film capacitors, paper & foil capacitors, feed-through capacitors, filtered connectors, and pulse forming networks. The resistor portfolio includes Precision Resistor Company, Hymeg, Tepro/Vamistor, and Custom Suppression, providing wire wound resistors, metal film resistors, thick film resistors, high voltage resistors, and EMI/RFI filters. The RF/Microwave portfolio includes Nova Microwave, Res-Net Microwave, RF Techniques, Southern Microwave, and Star Microwave, offering circulators, isolators, terminations, attenuators, and resistors. The magnetics portfolio includes Raycom and Hytronics providing custom transformers, inductors, and chokes. Recent innovation includes the HP Drive Test Kit - a domestic 800V+ SiC DC-link inverter solution for e-mobility developed by subsidiary Advanced Conversion.
