What API Delevan does

Delevan (formerly API Delevan) is a specialty manufacturer of high-reliability magnetic components and brushless resolvers, founded in 1947 and headquartered in East Aurora, New York. The company designs, manufactures, and distributes precision RF and power inductors, transformers, EMI/RFI suppressors, brushless resolvers, precision balls, and custom magnetics. Its products are specified into mission-critical applications across aerospace, defense, space, medical, oil and gas, industrial automation, and renewable energy, where component reliability under extreme operating conditions is required.

The core product lines center on fixed and variable inductors in surface-mount and through-hole form factors, magnetics qualified to military specifications, and brushless resolvers used for position feedback. Notable technical credentials include the only MIL-PRF-39010 Level "S" inductor qualification in the industry, ITAR registration, and AS9100 and ISO 9001 certifications. Manufacturing is conducted at facilities in East Aurora (USA), Tijuana (Mexico), and St. Kitts, supporting a build volume of more than 50 million standard products per year; approximately 40% of revenue derives from custom designs developed through engineer-to-engineer collaboration. The company also operates a product reliability program built on more than 250 million unit-hours of test data.

Delevan operates a hybrid direct-and-distributor sales model, with an authorized distributor network providing global reach and direct sales engineers handling OEM and program-specific engagements. Pricing is quote-based with a $250 minimum order, reflecting the configured-to-order nature of much of the catalog. Since 2023, the company has been a wholly-owned subsidiary of Regal Rexnord Corporation, operating within the parent's Automation Motion Control segment after the prior 2018 acquisition by Altra Industrial Motion. The October 2023 rebrand from "API Delevan" to "Delevan" and the January 2024 launch of an online Product Selector Tool indicate an ongoing effort to modernize brand positioning and self-service channel capabilities.
