What WEMS Electronics does
WEMS Electronics is a privately held, small-business manufacturer of electromagnetic interference (EMI) and radio frequency interference (RFI) filtering components for military, defense, aerospace, and space applications. Founded in 1959 and headquartered in Hawthorne, California, the company operates from a single facility with 51–100 employees and produces three interconnected product lines: EMI Filter Connectors (circular and rectangular connectors compliant with MIL-DTL-38999, MIL-DTL-26842, MIL-DTL-83723, MIL-DTL-26500, AS50151, MIL-DTL-24308, and MIL-DTL-83513, plus D-Sub and Micro-D variants with integrated filtering), Discrete/Multi-Circuit Filters (feed-through capacitor filters, low-pass filters in L/Pi/T topologies, and RFI power line filters spanning roughly 50V–600V and 5A–100A), and Contract Manufacturing for precision electronic assemblies and subsystems. Its filters address EMI sources ranging from motors, switches, and power supplies to radio transmitters, ESD, lightning, and sunspots, protecting avionics, radar, satellite communications, missile systems, and space launch vehicles.
The company's competitive position rests on MIL-spec qualified, hermetically sealed filter designs, a 65-year track record, and turn-key engineering services that span filter design, circuit analysis, power magnetics, magnetics analysis, layout and packaging, and qualification/acceptance test procedures. It holds AS9100:D, ISO 9001:2015, J-STD-001, IPC-610, MIL-PRF-15733, and MIL-PRF-28861 certifications, and sells exclusively via direct enterprise field sales to defense contractors, aerospace manufacturers, and government agencies — supported by trade show participation (APEC, IEEE Power Electronics Symposium), downloadable catalogs and design guides, and corporate social channels. Pricing is quote-based, with no public price list or e-commerce channel, reflecting the custom-engineered nature of the products. There are no disclosed funding rounds, acquisitions, subsidiaries, or parent companies; WEMS appears to operate as an independent, owner-managed specialty manufacturer.

WEMS Electronics product offering
Product offeringCore offering
WEMS Electronics designs and manufactures high-reliability multi-circuit and discrete feed-through input, output, power, and signal line EMI/RFI filters, as well as filter/shielded connectors for military, defense, aerospace, and space applications. The company also delivers turn-key contract manufacturing and custom EMI filter engineering services — including circuit analysis, power magnetics design, specification control drawings, and qualification testing — covering the full design-to-fabrication lifecycle of precision electronic components, assemblies, and subsystems.
Product overview
WEMS Electronics is a full-service turn-key small business established in 1959, specializing in state-of-the-art EMI custom filters, engineering, and manufacturing services. The company offers three interconnected product lines: EMI Filter Connectors (circular and rectangular filtered connectors including MIL-DTL series, D-Subminiature, and Micro-D variants), Discrete/Multi-Circuit Filters (feed-through capacitor filters, low pass filters, and RFI power line filters with various series designations), and Contract Manufacturing services. Together, these products form a completely integrated approach to the design and fabrication of precision electronic components, assemblies, and subsystems for military, defense, aerospace, and space applications.
