EMI Core
ESD-R Series Toroidal Cores
Overview
Benefits
Applications
The KEMET ESD-R Series solid
toroidal cores are designed for use on
round cable. A wide range of MnZn
and NiZn options are available in Bare,
Coated, and Case types.
•ꢀ MnZnꢀ(≤ꢀ100ꢀMHz,ꢀAMꢀbandꢀrange)ꢀ
andꢀNiZnꢀ(≤ꢀ300ꢀMHz,ꢀFMꢀbandꢀ
range) options available
• Solid construction
• Bare, Coated, and Case types
available
• Consumer

Turns and Impedance Characteristics
Figure 1 – How to count turns
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
onꢀtheꢀoutsideꢀofꢀtheꢀcoreꢀdoꢀnotꢀcount.ꢀSeeꢀFigureꢀ1ꢀforꢀ
examples of one, two, and three turns.
Figure 2 – Relationship between impedance and turn count.
(Representative example: ESD-R-16C)

Resonance point changes to lower band
Adding turns will result in higher impedance while also
loweringꢀtheꢀeffectiveꢀfrequencyꢀrange.ꢀSeeꢀFigureꢀ2ꢀforꢀ
an example.

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.
