CP-E55/28/21-1S Description

Short technical summary and product information.

The Ferroxcube CP-E55/28/21-1S is a bobbin coil former, part of the E55/28/21 series. This component is designed for use in magnetic transformer and inductor applications.

 

Key specifications include an effective volume of 44000 mm³, an effective length of 124 mm, and an effective area of 353 mm². The core factor is approximately 108 mm⁻¹. The dimensions of the former are 54.10 mm (A), 37.50 mm (B), 16.70 mm (C), 27.50 mm (D), 18.50 mm (E), and 21.00 mm (F).

 

Various material grades are available, each with specific inductance factors and power loss characteristics at different frequencies and magnetic flux densities. For example, material 3C91 offers an inductance factor of 8625 nH/turns² with a maximum power loss of 22 W/set at 100 kHz and 200 mT. Material 3F36 has an inductance factor of 4200 nH/turns² and exhibits a maximum power loss of 10 W/set at 500 kHz and 50 mT.

 

This coil former is suitable for applications requiring custom winding and integration into power magnetic components. It is compatible with accessories such as clasps, coil formers, and springs.
