Toroidal Transformer Solutions, Built to Your Specs
Pacific Transformer is a leading manufacturer of custom toroidal transformers. Toroidals offer significant advantages over conventional laminated transformers — smaller size, lighter weight, lower electromagnetic interference, quieter operation, and higher efficiency. Every toroidal we build is wound and assembled at our Anaheim, California facility to your exact specifications.
Power Toroidals
General-purpose power toroidal transformers for industrial equipment, power supplies, and commercial applications. Available from 5VA to 10kVA with custom primary and secondary voltages, our power toroidals deliver excellent regulation and low no-load losses.
Audio Toroidals
Ultra-low-noise toroidal transformers specifically designed for high-fidelity audio amplifiers, preamplifiers, and professional sound equipment. Our audio toroidals feature tight winding techniques and electrostatic shielding to minimize hum and electromagnetic interference.
Medical-Grade Toroidals
Toroidal transformers designed and manufactured to meet the stringent safety requirements of medical and dental equipment. Our medical-grade toroidals provide the reinforced insulation, low leakage current, and safety isolation required by UL 60601 and IEC 60601 standards.
Isolation Toroidals
Isolation toroidal transformers that provide complete galvanic separation between input and output circuits. Ideal for protecting sensitive instrumentation, IT equipment, and laboratory devices from line noise, voltage spikes, and ground loop interference.
Auto Toroidals
Toroidal autotransformers for efficient voltage adjustment applications. Our auto toroidals provide step-up or step-down voltage conversion in a compact, lightweight package — perfect for interfacing between different voltage systems where full isolation is not required.
High-Frequency Toroidals
Toroidal transformers designed for high-frequency switching power supply applications, wound on ferrite and powdered iron cores. Our high-frequency toroidals deliver excellent performance in DC-DC converters, inverters, and resonant power conversion circuits.
Encapsulated Toroidals
Fully potted or encapsulated toroidal transformers for harsh environments where moisture, vibration, dust, and chemical exposure demand maximum protection. Our encapsulated toroidals are ideal for outdoor equipment, marine applications, and industrial machinery.
Miniature Toroidals
Compact toroidal transformers for space-constrained applications where size and weight are critical. Our miniature toroidals deliver full performance in a fraction of the footprint — perfect for portable instruments, embedded systems, and PCB-mount applications.
Industries Served
Pacific Transformer's custom toroidal transformers serve a wide range of industries including audio and pro sound, medical and dental equipment, aerospace and defense, industrial automation, marine electronics, renewable energy, and telecommunications. Our toroidals are trusted wherever low noise, compact size, and high efficiency are essential.
