kOr 118 is a nanocrystalline material specifically optimised for very high permeability and excellent linearity at low frequencies (50 Hz). This material has been developed especially for RCCB applications, and can also be used for CTs or CMCs where no DC parts (as common mode current in case of CMCs) are present. Cores are packed in plastic cases; Epoxy coating is possible with minor influence on linearity for µ_max up to 150.000.

Features optimum combination of high linearity and highest permeability for example as RCCB core: Bdyn/Bsin > 0,85 at µmax = 150.000 and >0,80 at µmax = 200.000 Negative temperature coefficient µ(T) or constant permeability over temperature adjustable Benefits available in plastic case or Epoxy coated (up to permeability of 150.000) to minimise required space small tolerances available by sorting into groups view datasheet view brochure

kOr 120 products are made of an iron-based nanocrystalline material optimised for power and EMI applications, they have high saturation flux density, low losses, high permeability up to 100kHz and low magnetostriction. Different B(H) characteristics are available.

With flat hysteresis loop (F-loop), low remnant flux B_r and adjustable permeability between 25.000 and 120.000 (at 10kHz), they are the preferred choice for mid-frequency power applications and common mode chokes with wideband attenuation. Our standard 120-TB-series includes selected core sizes in plastic cases with a lower limit of specified A_L -range between 25.000 and 80.000 (10 kHz). The variant kOr 120HF with ultra-thin ribbon is the perfect choice for high frequency: transformers for >30 kHz, and optimised CMCs.

With rectangular Z-loop, they are an cost effective alternative for MagAmps and other switching applications.

Features High saturation flux density (1.2 T) High Curie temperature (580ºC) and excellent temperature characteristics Near-zero magnetostriction Benefits Applicable for transformers and common mode chokes Low losses, especially using kOr 120HF, allow high flux density at medium frequencies, ie reduced space Standard sizes with adjustable permeability, ie tailored inductance and DC tolerance Size and finishing can be customised easily, available also as cut cores view datasheet view brochure

kOr 122 extends our nanocrystalline material cores range to permeability down to 4000. Cores are ideal for use in transformers and CMCs with medium non-balanced common mode current.. They show high linearity µ(I_DC) and frequency behavior µ(f), so permeability at 100 kHz is very close to 10- kHz value. These cores are offered in plastic case.

Features high saturation flux density (1,2 T) high linearity µ(IDC) and µ(f) excellent long-term stability even at high temperature Benefits Applicable for transformers and Common Mode Chokes with high currents big variety for shape, size and finishing according to space and mechanical requirements, for example big oval cores view datasheet view brochure

kOr 156 products are made of an iron-based amorphous material which has been developed as a contemporary replacement for electrical steel. Low losses compared with steel make components highly efficient in both purchasing and operational costs for low frequency applications, and even mid frequency applications as cut cores. We offer standard cut cores and a broad variety of customised shapes and finishings.

Features Low losses compared with silicon steel High BS (1,56 T), good linearity and frequency characteristics Effective permeability (hence: AL) and DC-tolerance adjustable with gaps Benefits Applicable ideally for transformers Standard size cut cores match perfectly to standard bobbins Size and shape adjustable to space limitations view datasheet view brochure

kOr 140 is a further development of kOr 120 / kOr 122 to increase the flux density but keeping good loss level. Target applications are mid frequency transformers and Common Mode Chokes for high nominal and/or non-balanced currents. The permeability can be adjusted between 30.000 and 70.000 for cores with F-shape hysteresis loop. Cores are available in plastic case and Epoxy impregnated, with or without cuts.

A version with ultra-thin ribbon, resulting in lower losses and higher 100 kHz permeability is also available for this material.

Features Improved saturation flux density (1,4 T) Low losses, further optimised with kOr 140HF Low magnetostriction allowing also impregnated cores Benefits Applicable ideally for transformers Even smaller designs possible compared to kOr 120 in the mid frequency range up to 20-30 kHz, and for high current CMCs Size and shape adjustable to space limitations view datasheet

kOr 170 is the latest development result to maximise flux density of nanocrystalline material towards electrical steel, but reduce losses even compared to the common alternative for steel, kOr 156. Losses are in between kOr 120 / kOr 140 and kOr 156, and permeability is at a reliable level up to 100 kHz, which make the material the perfect choice for power applications at 1 - 8 kHz.

We started our offer with toroids in plastic case. Magnetostriction is lower than for kOr 156 which also allows usage of impregnated cores.

Features Highest flux density for amorphous and nanocrystalline materials Best loss level for high-Bs materials Initial permeability around 10.000; at 100 kHz: 6000 Reliable magnetostriction (15 ppm) Benefits Smallest designs possible for power applications at about 1 - 8 kHz Reliable permeability up to high frequencies Customised shape and size view datasheet
