Inductors are everywhere — from phone chargers to data centers to EVs. But not all inductors are the same. The two main families are air-core (no magnetic material inside) and magnetic-core (using materials like ferrite or powdered iron). Each has trade-offs in size, efficiency, frequency, and cost. Here’s a practical […]
Most projects can live with a catalog or general transformer design, but some can’t. Tight noise limits, unusual envelopes, tough environments, or non-standard frequencies push you beyond “good enough.” That’s where a custom rather than general transformer design pays for itself—and where core material and lamination strategy (M6, M29, M50, […]
At Custom Magnetics, we specialize in designing and manufacturing high-voltage electronic transformers and coils, tailored for a range of precision applications across multiple industries. Unlike power transformers used in the power grid for voltage regulation, our high voltage transformers are specifically designed to meet the unique needs of applications where […]
At Custom Magnetics, we manufacture a variety of transformers for audio equipment and medical devices, where precision is crucial and unnecessary noise has to be reduced to ensure optimal performance. Typically, for applications like these, our customers require R-core transformers, a unique type of transformer designed to almost eliminate leakage […]
Current transformers (CTs) and potential transformers (PTs) are crucial components for current and voltage monitoring. They measure the current and voltage of various power systems, ensuring these systems maintain precise and safe outputs, and they’re often used together to ensure that all instrument transformers are functioning properly. However, while they […]
Linear Power Supplies vs. Switch Mode Power Supplies (SMPS): Picking the Right Tool for the Right Application The electronics industry has seen major shifts in power supply design, with switch-mode power supplies (SMPS) taking the lead in many applications due to their efficiency, compact size, and versatility. However, linear power […]
Ignition coils are an essential component for nearly all engine types, providing the necessary voltage to ignite the spark plugs and ensure proper engine operation. Without them, generating the high voltage required for spark plugs would be impossible. In certain engine applications, ignition coils are designed to ensure enhanced safety, […]
Choke coils (chokes) are essential components in electrical and electronic systems. They offer critical functions such as noise filtering, stabilizing current, and protecting sensitive circuits from electromagnetic interference (EMI). Selecting the right choke ensures system efficiency, performance, and compliance with stringent noise-reduction standards.In this blog, we explore the types of […]
Transformers are a crucial part of any electric equipment or electronic system, and despite their simplicity, they are incredibly versatile little components that play a huge role in performance, quality, and long-term functionality. The impact of transformers can be best seen in audio equipment like recording equipment, amplifiers, microphones, loud […]
