Do not heat stable ferrites for weak magnetic fields



the Main fields of application

Cores of Ni-Zn ferrites brands NN применятют in weak and medium-sized magnetic fields (Vac 0,05- 0,2 T) in the absence of strict requirements for temperature and time stability: in deflecting systems tubes of TV receivers in the inductors correction schemes, in magnetic antennas and circuits input circuits of radio receivers.

Cores from ferrite grades NN is recommended when the ambient temperature is from 60ºC to +90ºC, and in the frequency range: 100НН –up to 30 Mhz, 400НН –up to 3.5 Mhz, 600НН –up to 1.5 Mhz, 1000НН – up to 400 Khz.

Cores of Mn-Zn ferrites brands NM is used in the weak and medium-sized magnetic fields (Vac 0,2 0,05 T) in the absence of strict requirements for temperature and time stability: in transformers and inductors one- and two-stroke DC/DC DC/AC AC/AC converters, network filters, filters RF-interference, in high-voltage transformers, pulse, matching and decoupling signal transformers, inductors BASS- filters of acoustic systems, in dividers voltage static converters.

Cores from ferrite grades NM is recommended when the ambient temperature is from 60ºC to +155º and in the frequency range: 1000НМ – up to 1 Mhz; 1500НМ – up to 600 Khz; 2000НМ, 3000НМ – up to 450 Khz.
