In addition to the transformers, the company also provides the following magnetic components:

• Antennas and Air Coils: The Company provides these coils in a wide variety of shapes, sizes, and styles. These antennas and air coils feature self-support coils, high turns count, and fine gauge wires.
• DC Igniters: Custom Coils specializes in the design and manufacturing of 12V DC igniters. These igniters are well-known for their special features such as internal reverse polarity protection, internal transient voltage protection, internal midpoint ground, etc.
• Downhole Applications: Downhole magnetics is one of the specializations of Custom Coils. Most of the downhole magnetics are designed for temperatures 200 °C and 220 °C, whereas some coils are also designed for 240 °C.    
• High Current Inductors: These inductors are designed for low voltage, high current power supplies. The current ratings for these high current inductors are above 100 Amps.
• Hydrogen Coils: The hydrogen generator coils provided by the company features 2000 turns of 23 AWG magnet wire, which are neatly wound around a ferrite toroid core. Special variations of these coils are also provided.
• Toroidal Inductors: Designed to protect and support the equipment from Electromagnetic Interference (EMI), these inductors are widely utilized by several critical applications. Customized designs are also provided on the basis of specifications including tolerance, current rating, DC resistance, etc.
• Air Core Inductors: Also known as air core coils, these non-magnetic inductors are used in commercial and industrial applications with low inductance and high-frequency requirements.  
• Ferrite Inductors: Capable of meeting a wide range of inductance values, these magnetic devices are available in a variety of ferrite geometries. These inductors are used in both – high and low-frequency applications.   
• Power Inductors: These devices are designed for electrical circuits, which is regularly subjected to high current and voltage fluctuations without saturation. Power inductors can minimize the loss of signal in a system.
• Surface Mount Inductors: Regularly used in fluctuating power circuits to filter EMI currents with minimal inductance loss, these devices are majorly used in DC-to-DC and AC-to-DC conductors.
