Coast ACM

What Coast ACM does

Coast ACM (legal name: Coast Advanced Chip Magnetics, also doing business as Coast/ACM) is a privately held manufacturer of high-reliability magnetic components founded in 1952 and headquartered in a single Torrance, California facility. The company designs and produces RF and power magnetic components including fixed and variable chip inductors, toroidal inductors, power inductors, common mode inductors, current transformers, and wideband transformers, organized into a multi-series product catalog that spans hundreds of part numbers. Its core technology centers on precision magnetic component manufacturing with transfer molded package construction, laser marking, internal welded terminations, and tight electrical tolerances (inductance ranges from 0.005 µH to 10,000 µH, operating temperatures from -55°C to 125°C, tolerances from ±1% to ±20%) suitable for harsh-environment RF and power applications.

Coast ACM qualifies its products under multiple U.S. federal defense specifications, including QPL listings under MIL-PRF-83446 (chip inductors), MIL-PRF-15305 (toroidal inductors), MIL-PRF-27 (power inductors), and MIL-STD-981 (space-level products), plus NASA SP-R-0022A outgassing compliance (TML less than 1%). Each product series is offered in three quality tiers — Space-Level (S prefix), Military-Level, and Commercial-Level (C prefix) — allowing customers to select components matched to program criticality. The primary customer segments are defense and military electronics contractors and space and aerospace programs, with a secondary commercial electronics segment.

The business model is direct sales: customers request quotes via the company website or by contacting the sales team directly, and orders are fulfilled through a direct sales channel without distributors or resellers. Pricing is quote-based, contract cadences can extend over multiple years, and customization services are offered for specialized applications beyond the standard catalog. The company has 1-10 employees, no disclosed external funding, no parent company, and no subsidiaries, operating as an independent, privately held specialty manufacturer.
