What Lenco Electronics does
Lenco Electronics, Inc. is a privately held U.S. manufacturer of custom transformers and inductors, founded in 1973 and headquartered in McHenry, Illinois. The company designs and builds magnetic components using ferrite, iron powder, lamination, and amorphous alloy cores paired with magnet wire, litz wire, copper foil, and aluminum foil conductors. Its product portfolio spans six categories — Custom Transformers, Custom Inductors, Three-Phase Transformers, PCB Transformers, Constant Voltage Transformers, and Autotransformers — covering single-phase units from 10mW to 25KVA and three-phase units from 7VA to 75KVA. Manufacturing is supported by Vacuum Pressure Impregnation (VPI) epoxy processing, multi-layer winding equipment capable of winding up to 25 coils simultaneously, and ISO 9001:2015 quality certification.
The firm operates a sales-led, quote-based business model targeting industrial equipment manufacturers, factories using European-standard machinery, commercial buildings, IT and data infrastructure, green energy installations, and medical equipment OEMs (with UL 2601/IEC 601 capability). Pricing is custom per unit, supported by low-cost samples and design support from prototype (1 unit) through production (100,000+ units). In-stock standard products are available for immediate delivery alongside custom builds. Products are built to UL, CSA, TUV, and IEC standards, with worldwide delivery enabled by proximity to O'Hare Airport.
The company employs approximately 45 people across 2 manufacturing facilities totaling roughly 25,000 sq.ft., with over 50% of staff holding 10+ years of tenure. Go-to-market relies on direct enterprise engagement through a website-driven RFQ process, a corporate blog, and a Facebook presence; there is no public listing, no disclosed external funding, and no parent or subsidiary relationships.

Lenco Electronics product offering
Product offeringCore offering
Lenco Electronics designs and manufactures custom transformers and inductors ranging from compact PCB transformers to single-phase units (10mW to 25KVA) and three-phase units (7VA to 75KVA), using ferrites, iron powder, laminations, and amorphous alloy cores with magnet wire, litz wire, copper foil, and aluminum foil conductors. The company also offers in-stock standard products including Constant Voltage Transformers and Autotransformers, with design and manufacturing support from prototype (1 unit) through high-volume production (100,000+ units).
Product overview
Lenco Electronics is a manufacturer of custom transformers and inductors, established in 1973 in McHenry, IL. The company's product portfolio centers on six main product lines: Custom Transformers, Custom Inductors, Three-Phase Transformers, PCB Transformers, Constant Voltage Transformers, and Autotransformers. Custom Transformers serve as the core offering with types including audio, switch mode, medical, converter, isolation, control, and 400Hz transformers. Custom Inductors complement the transformer line with various reactor types (AC line, DC filter, harmonic filter, etc.). Three-phase units cover isolation and autotransformer configurations from 7VA to 75KVA. PCB Transformers address compact mounting needs, while Constant Voltage Transformers provide voltage regulation. Autotransformers offer step-up/step-down functionality. All products support custom design from prototype through production with volumes from 1 to 100,000+ units.
