Industries We Serve
Custom Magnetic Components for Demanding Applications
For more than fifty years, Custom Magnetics Inc. has designed and manufactured transformers, inductors and coils for equipment that must perform reliably—whether on a factory floor, inside a medical device, powering a locomotive, or driving a guitar amplifier. Across every industry we serve, our components are engineered for long-term stability, electrical performance, and environmental durability.
From audio production to energy systems, from small engines to industrial automation, OEMs and repair professionals rely on Custom Magnetics for custom designs, reverse engineering, prototyping, and full‑scale production; all backed by ISO 9001:2015 certified processes.
Audio Production
Custom Magnetics builds high‑performance audio transformers, chokes and power‑supply components for recording studios, live sound rigs and music‑production equipment. Our designs preserve signal integrity, deliver low distortion, and are voiced for specific musical styles, from hard rock to blues to funk. Applications include recording consoles, amplifiers, preamps, intercoms and music‑reproduction equipment.
Medical Equipment
Medical devices demand absolute reliability and strict regulatory compliance. We manufacture transformers, inductors and coils engineered for patient‑connected circuits, diagnostic equipment, imaging systems and laboratory instruments. Capabilities include medical‑grade isolation, creepage/clearance compliance, low leakage current and full documentation for regulatory submissions.
Oil & Gas
Oil & gas equipment operates in extreme environments—heat, vibration, corrosive atmospheres and nonstop duty cycles. We build rugged transformers and inductors for drilling rigs, pipeline monitoring, refineries and compressor stations. Solutions include high‑temperature insulation, moisture‑resistant potting, corrosion‑resistant hardware and fast turnaround for critical project timelines.
Industrial Equipment & Manufacturing
Factories and automation systems depend on magnetic components that run continuously under heat, vibration and electrical noise. We supply transformers, inductors and coils for robotics, motor controls, automation equipment, test systems and heavy machinery. Designed for stable performance, noise suppression, harsh environments and tight production schedules.
Small Engine & Outdoor Power Equipment
We design ignition coils for lawn equipment, generators, chainsaws, trimmers, blowers and other outdoor power machinery. Our coils match OEM timing, voltage and spark‑energy requirements—and we reverse‑engineer obsolete coils when replacements no longer exist. Built for moisture resistance, debris protection, thermal cycling and high‑RPM operation.
Railroad
Rail systems rely on magnetic components for ignition, onboard power, noise suppression and signal systems. We build locomotive ignition coils, power transformers, chokes and isolation components engineered for vibration, temperature swings and decades of continuous duty. We also provide reverse engineering for obsolete railroad components.
Energy & Power Systems
Power generation, transmission and storage equipment require magnetics that withstand high voltages, wide temperature swings and demanding duty cycles. We supply transformers, reactors and coils for renewable energy systems, substations, industrial power supplies and battery storage. Capabilities include fault‑current limiting reactors, harmonic filters, and high‑frequency ferrite designs for modern converters.
Electronics
Modern electronics demand compact, thermally stable magnetic components with tight tolerances. We build laminated, toroidal and ferrite transformers along with chokes, inductors and current‑sense coils for consumer devices, industrial controls, medical electronics and communication gear. Designed for PCB‑specific footprints, surface‑mount or through‑hole configurations, and controlled temperature rise.
