EMI Cores ESD-R-SR Toroidal Cores for Round Cables for Low Frequency at 150 kHz (Bare, coated & with case) Overview Applications The KEMET ESD-R-SR Series solid toroidal cores are designed for use on round cables. KEMET’s unique core material enables high performance in low frequency range, at 150 kHz. Options are available in bare, coated and with case types.

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. 1T Adding turns will result in higher impedance while also lowering the effective frequency range. 10,000 Core Material and Effective Frequency Range 100 10 1 3T 2T 1T 1 10 100 1,000 Frequency (MHz) 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 MnZn core material has a lower resistance compared to the Ni-Zn; therefore, adequate insulation is required before use. © KEMET Electronics Corporation • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com 1,000 Impedance Increase Impedance (Ω) Resonance point changes to lower band See Figure 2 for an example. It is recommended to measure the actual frequency range effectiveness in the target application. 3T Figure 2 – Relationship between impedance and turn count. (Representative example: ESD-R-16C) See Figure 1 for examples of one, two, and three turns. Figure 3 – Effective band range of Mn-Zn and Ni-Zn ferrite core material. (Representative example, measured with same-dimension ring core) 1,000 AM band range Impedance (Ω) The Ni-Zn core material is typically effective for frequencies in the MHz band range such as the FM-band, while the Mn-Zn core material is typically effective for the kHz band range such as the AM-band.

Depending on its magnetic permeability, a particular ferrite material will be effective in a certain frequency band. A schematic representation of the relationship between the magnetic permeability of each material and the corresponding effective band range is shown in Figure 4. Materials with higher magnetic permeability are effective in the lower frequency range, while those with lower magnetic permeability are effective in the higher frequency range. Thus, Mn-Zn products are mainly used for reducing conduction noise, while Ni-Zn products are commonly used for radiation noise countermeasures. The effective frequency range varies depending on core shape, size and number of turns. This frequency dependence of the magnetic permeability as shown in the figure serves for reference purposes only and it should be tested on the actual device to determine its effectiveness. S18H, S15H, 10H, 7H, 7HT, 5H, 5HT, HR1, 1400L and 700L are KEMET’s proprietary ferrite material names. Other materials can also be available on request.

While the EMI Cores themselves are quite robust in other environments, avoid exposure to high temperatures, high humidity, corrosive atmospheres and long term storage for case, snap-on and split types. KEMET recommends that maximum storage temperature not exceed 40°C and maximum storage humidity not exceed 75% relative humidity. Atmospheres should be free of chlorine, sulfur and alkali bearing compounds. Avoid also storage near strong magnetic fields as this might magnetize the product. Temperature fluctuations should be minimized to avoid condensation or cracks on the parts. Mechanical shocks can bring to cracks as well. © KEMET Electronics Corporation • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com E5010_ESD-R-SR • 11/9/2023 9 EMI Core – ESD-R-SR Toroidal Cores for Round Cables for Low Frequency at 150 kHz (Bare, coated & with case) KEMET Electronics Corporation Sales Offices For a complete list of our global sales offices, please visit www.kemet.com/sales.
