What TDK-Lambda does

TDK-Lambda is a wholly-owned subsidiary of TDK Corporation and a global manufacturer of power conversion products, operating across AC-DC power supplies, DC-DC converters, programmable power supplies, and EMI filters. Originally founded as Lambda in 1948 and acquired by TDK in 2005, the company anchors its UK headquarters in Ilfracombe with extensive EMEA operations across Germany (Achern), France (Les Ulis), Italy, Netherlands, Switzerland, Austria, Denmark, and Israel. The product portfolio spans 1.5W to 15kW for standard offerings and up to 60kW for programmable systems (GENESYS+ and GSPS series), addressing applications in medical equipment, factory automation, test and measurement, semiconductor fabrication, renewable energy, commercial aerospace, railway, LED lighting, broadcast, and automotive/marine rugged environments.

The company's technology base rests on proprietary power electronics innovation, including patented non-isolated buck-boost DC-DC converters achieving up to 99% efficiency (i9C series with PHEPT technology), ORing modules at 99.5% efficiency, third-generation 1500W AC-DC modules, and configurable programmable platforms. Revenue is generated primarily through hardware sales of standard catalog products and custom/purpose-built solutions, with pricing conducted on a quote basis rather than published rates. Distribution follows a hybrid model: direct sales offices in 9 EMEA countries, global catalog distributors (Arrow Electronics, Digi-Key, Farnell, Mouser, RS Group), regional specialist distributors across Iberia, Africa, and Latin America, and design-in focused channel partners supporting OEM integration.

Recent strategic activity includes a flagship technology partnership with Porsche Motorsport (announced January 2026), sustained product launches across DIN-rail, modular, and DC-DC converter categories through 2025-2026 (D1SE, DDSM, MU Series, DRB 3 Phase, i9C, CCGS), Top Employer 2024 recognition in Germany, and continued digital channel build-out via the Quick Product Finder configurator and multi-language Technical Centre. The company operates under a horizontal segmentation strategy, serving diverse verticals with standardized and custom-engineered power solutions.
