What Electrocube does

Electrocube, founded in 1961 and headquartered with manufacturing operations in Pomona, California, designs and manufactures passive power electronics components for flight-critical and industrial applications. Its product portfolio spans film capacitors (multiple series with polyester, PPS, polycarbonate, polypropylene, and PTFE dielectrics), high-frequency foil-wound transformers built on a proprietary aluminum/copper foil winding process (300 Hz–10 KHz, 25 VA–50 KVA, -50°C to 250°C ambient), transformer rectifier units (TRUs), current transformers, custom EMI/RFI filters (0.1–500 A, up to 5000 VDC / 660 VAC), and a catalog of over 400 UL-recognized RC networks. Aerospace and defense OEMs — explicitly Boeing, Honeywell, GE Aerospace, Crane Aerospace Electronics, and Parker — are the primary customer base; secondary segments include industrial, renewable energy, medical, audio, appliance, and transportation applications.

The company's business model is hardware sales of custom and standard components, priced on a quote basis with no non-recurring engineering (NRE) charges; Electrocube absorbs upfront engineering costs as a customer acquisition lever. Distribution runs through two parallel channels: direct enterprise sales to major aerospace OEMs, supported by a field engineering team including aerospace-trained engineers, and an authorized distributor network spanning 30+ US states and international markets across Canada, China, Hong Kong, India, Japan, Mexico, Philippines, the United Kingdom, and Taiwan, with master distributors such as Master Electronics, Future Electronics, Hughes-Peters, Masline Electronics, and Beyond Components. Quality and qualification are anchored by ISO 9001 / AS9100D certification, ITAR registration, UL recognition, and in-house DO-160 qualification testing accessed through parent company Amca.

Electrocube was privately held by two founding families from 1961 until its acquisition by Amca, the El Segundo-based aerospace and defense strategic operator, in February 2026. Post-acquisition, the company operates as a wholly-owned subsidiary with reported plans for first-year investment in engineering headcount and product catalog expansion; it ranked in the top 20 of more than 5,000 Boeing suppliers for quality and on-time delivery and supplies components across 35+ commercial and defense aircraft platforms including Boeing 737/747/757/767/777, C-17, F-15, F-16, and P-8.

• Film Capacitors Metallized and foil film capacitors in multiple series (including 230-232A, 247A-248A, 250-252A, and 226 families) built from polyester, polyphenylene sulfide, polycarbonate, polypropylene, and PTFE dielectrics. Designed for aerospace, industrial, and commercial applications including aerospace power systems, industrial machinery, audio, medical, and renewable energy.
• Foil Transformers High-frequency aluminum and copper foil transformers for aerospace applications using proprietary foil winding instead of standard copper wire. Frequency range 300 Hz to 10 KHz, power range 25 VA to 50 KVA, ambient temperature range -50°C to 250°C. Targeted at aerospace power conversion programs.
• Transformer Rectifier Units (TRUs) Custom transformer rectifier units designed with lightweight high-reliability foil transformers, supporting multi-phase or pulsed output that reduces output EMI filter requirement and saves weight and size. Power range 5 KVA to 50 KVA, output current 3 to 100 amps, with hermetically-sealed variants available for aerospace platforms.
• Current Transformers Instrument transformers for power system wiring protection and power supply control used in commercial jetliners, military aircraft, and land-based defense facilities. Available in single-phase and multi-phase configurations.
• Custom EMI Filters Fully custom designed, manufactured, and tested EMI and RFI filters developed with computer simulation. Capacities 0.1 AMP to 500 AMPS, voltage ratings 1 VDC to 5000 VDC and up to 660 VAC, frequency up to 1000 Hz. Single- and multi-circuit configurations include L, Pi, and T circuit topologies for aerospace, defense, and industrial customers.
