What HALO Electronics does

HALO Electronics is a privately held manufacturer of electromagnetic components founded in 1991 and headquartered in Santa Clara, California (incorporated in Nevada). The company designs and produces magnetic components for communications and power management — including discrete Ethernet transformers, integrated RJ45 FastJack connectors, DC/DC converters and transformers, telecom isolation modules, inductors, RF and digital audio transformers, and RJ45 connectors. Its product range covers Ethernet speeds from 10BASE-T to 25G/40G, plus Single Pair Ethernet (2.5GBASE-T1), with key proprietary platforms including the GEmini series (compact PoE/PoE+ transformers reducing PCB real estate by up to 50%), the Tele-Pro series (lightning-protected telecom modules), the patent-pending UWBX high-speed transformer technology acquired via investment in UWB X Limited, and Pro-Tek5 Ethernet isolators. HALO is qualified to AEC-Q200 for automotive Ethernet and holds ISO 9001, ISO 14001, IATF 16949, UL, and GR1089 certifications across its manufacturing operations.

The company serves enterprise networking equipment manufacturers, automotive electronics suppliers, telecom equipment vendors, and industrial/power management customers — with reference designs validated against Broadcom, Marvell, Maxim (now Analog Devices), Analog Devices, and Texas Instruments silicon. HALO operates a channel-first go-to-market, distributing through Mouser Electronics (global), franchised distributors, and regional manufacturer representatives (e.g., RedTree Solutions in the Nordics). Pricing is quote-based and not publicly disclosed. Manufacturing runs through three facilities: Zhongshan and Debao in China, and a new Vietnam plant opened in November 2025 — the company's first location outside China — to support customer supply-chain diversification. The company has defended and monetized its SMD magnetic component packaging patents, including a 2016 U.S. Supreme Court victory in Halo Electronics v. Pulse Electronics, and has licensed that portfolio to five competitors (Bel Fuse, Wurth Electronics Midcom, Bourns, XFMRS, and Elec & Eltek). Leadership is family-influenced, with Jeffrey Heaton (VP) and JP Heaton (Marketing Director), and the company remains privately held with no disclosed institutional investors or funding rounds.
