Air Core Coils
An air core coil is an inductor that does not depend upon ferromagnetic materials to achieve its specific inductance. Its inductance is quite low and the magnetization characteristic curve is linear. Air core coils show no magnetic saturation compared to coils with magnetic cores.
Auxiliary Coil
GT Electronic India offers all types of customized auxiliary coils, depending on the requirements of our customers. Regularly auxiliary coils are used in relays.
Solenoid Coils
Solenoid coils just look like a simple coil of wire, but when current passes through it, it becomes an electromagnet. Electromagnets are particularly useful besides regular magnets, because they can be switched on and off and strengthened by increasing the passed current. Solenoid coils are used in relays, water pressure valve, hard disk drive, speakers, MRI machine, cars etc.
Rogowski Coils
Rogowski coils are “air-coated” toroidal coils located around the conductor. The alternating magnetic field, produced by the current, induces a voltage in the coil, which is proportional to the rate of change. They are used for measuring AC current or high speed current pulse. For Rogowski coils, the winding must be as evenly as possible. Uneven windings cause susceptibility at magnetic pickup in adjacent conductors or other sources of magnetic fields. To avoid such errors, GT Electronic India uses a special machine for accurate windings.
Storage Chokes
Storage chokes are used for energy storage in SMPS components. They are usually made of iron or metal powder cores with one winding. When the inductance decreases with increasing load current, the load current is typically selected at 60% to 75% of the non-load inductance.
Common Mode Choke
The CMC chokes (two /more coils are wound on a single core) are used for prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines and for prevention of malfunctioning of electronic equipment. Enquiry
Current Compensated Suppression Choke
These chokes are based on high-permeability toroid core (ferrite) with two symmetrical windings, so the magnetic fields are cancelling each other. They are mainly used in devices with switched-mode power supplies.
Rod Core / Drum Core Inductor
For rod core/drum core inductors, the wire is wound directly on the core. The core shape is typically cylindrical or cylindrical with end caps.
Power Factor Correction Chokes (PFC)
GT Electronic India optimizes a Power Factor Correction (PFC) solution for any specific application. PFC chokes are made of core with one main winding and an auxiliary winding, if needed. PFC chokes are used to reduce significantly harmonic distortions – generally in line with the main supply in SMPS components.
