FPL27 Datasheet – Solid EMI Core – Kemet ( PDF )

Part Number: FPL27

Function: EMI Core / ESD-FPL Series Solid Cores for Flat Cables

Manufacturer: KEMET

Image and Pinouts:

FPL27 datasheet



The KEMET ESD-FPL Series solid cores are designed for use on flat cable. A wide range of sizes and shapes are available.


1. Solid construction
2. Thin and Minimal Gap types available


1. Consumer electronics


Turns and Impedance Characteristics

When the desired performance of an EMI core cannot be obtained with a single pass through the core, the impedance characteristics can be changed with multiple turns.

A turn is counted by the number of lead-wire windings which pass through the inner hole of the core. Windings on the outside of the core do not count.


Core Material and Effective Frequency Range :

There are two ferrite material options for KEMET EMI Cores: Nickel-Zinc (Ni-Zn) and
Manganese-Zinc (Mn-Zn). Each core material has a different resistance and effective
frequency range. The Mn-Zn core material has lower resistance compared to the Ni-Zn; therefore, be sure to provide adequate insulation before use.
