EP cores, ideally utilized in power inductors, offer a low profile and exceptional self-shielding capabilities. Their cubical design maximizes volume-to-surface ratio, although they provide less winding space. Available in sizes such as EP7, EP10, EP13, EP15, and EP20, these cores are perfect for differential and telecom inductors as well as power transformers, combining benefits like excellent shielding and a compact form with the drawback of limited winding space.
EFC Cores are renowned for their outstanding space efficiency, available in sizes such as EFC2508, and are perfect for compact transformer applications. Although they come at a premium compared to E cores, their superior performance and space utilization make them the ideal choice for high-demand applications like lighting. These cores exemplify precision engineering, delivering exceptional efficiency in confined spaces.
ER Cores, also known as EER Cores, are economical options for inductors and transformers, designed to minimize winding resistance and maximize efficiency. They are available in sizes such as EER2811, EER2811A, EER2811B, EER3511, and EER3913, commonly used in applications like differential inductors and power transformers.
ETD Cores are costeffective options for transformers and inductors, designed to minimize winding resistance and maximize efficiency. Despite being more expensive than E cores, they are available in sizes such as ETD2910, ETD3411, ETD3411A, and ETD3913, suitable for applications like differential inductors and power transformers.
Toroid cores, also known as ferrite rings, are compact soft ferrite cores made from MnZn. They are highly efficient in magnetic performance and resistant to external magnetic fields. With a uniform cross sectional area and optional coatings for increased breakdown voltage, toroidal cores are lightweight and space efficient. Their round shape allows for easy containment of magnetic flux, reducing electromagnetic interference (EMI) emissions. These features make them ideal for applications requiring high efficiency and low EMI.
I Cores are ideal for higher power applications in limited spaces or unconventional form factors, offering low leakage inductance and superior voltage isolation. They are available in sizes such as I12620, I2020, I2830, I3016, I3030, I5125, I5509, I5814, I6004, I6015, I6204, I7020, and more, commonly used in power transformer applications.
Planar (EI, EE) Cores are designed for making gapped inductor cores, minimizing fringing losses with their efficient design. They offer no wasted space but are priced slightly higher than other cores. Available in sizes such as EE1804P and EE6430P, these cores are commonly used in applications like differential inductors and DC/DC, AC/DC converters.
PM Cores provide excellent self shielding capabilities and are capable of handling large power with thermal stability. They are available in sizes such as PM6249 and PM8770, commonly used in applications like differential and telecom inductors, as well as power transformers.
POT Cores offer the benefits of lowest leakage inductance and high Q, providing perfect isolation from stray magnetic fields and temperature stable inductance. They undergo a complicated gapping process to maintain AL value and are available in sizes such as P0903, P1408, P1811, P2213, P2616, P3019, P3019A, P3422H, and P3622. Common applications for POT cores include broadband and narrow transformers, telecom inductors, power transformers, and power inductors.
