Termostable ferrites for weak magnetic fields



the Main fields of application

Cores for the RF paths, transformers HF frequency range, cores for filters RF-interference, antenna couplers, dividers and faucets HF frequency range.

Cores from ferrite grades DOWN it is recommended to use in weak magnetic fields at an ambient temperature of 60 º C to +125 º C, and in the frequency range: 20VN - up to 100 Mhz, 30VN - up to 120 Mhz, 50VN-up to 50MHz.

Cores of ferrites brands HV is not recommended for use in magnetic fields greater than the so-called threshold of the field, because in excess of the specified field values ​​is a significant decrease of good quality. The value of the threshold field are: to 20VN, 30VN 50VN and -150 A / mμn it practically does not change.

inductors and podstroechniki with a high q-factor in the operating frequency range and with small values ​​of the relative temperature coefficient μn to telephone and radio communications equipment (including for railway the means of communication).

Cores from ferrite grades nm1, NM3 it is recommended to use at ambient temperature from 60 º C to +150 º C, and in the frequency range: 1500NM1, 1500NM3 - up to 600 Khz, 2000NM1 - up to 450 Khz.
