Fixed Inductors

IM02BHR33J is a kind of fixed inductors. It is small size, low cost, without insulation and with low resistance. It has the characteristic of high saturation magnetic permeability and an insulated core which makes it difficult to be saturated and good performance in temperature range.

Application Field

IM02BHR33J is mainly used in mobile handsets, Bluetooth receivers and other devices as electromagnetic interference suppresser. It can also be used in pulse circuits, power supply lines, to prevent EMI in high frequency and high current applications.

Working Principle

IM02BHR33J works on the principle of induction. When current passes through it, the energy in the coil or coils is stored in the magnetic field and acts as a barrier to the passing current. This stored magnetic field energy will then be released and creates counter EMF to the passing current.

In the case of IM02BHR33J, the inductor can act as a filter to get rid of undesired high frequency noise. This is because the frequency of the ripple current is close to the resonance frequency of the inductor. The resonance of the inductor will then absorb and reject the noise.

Furthermore, the same concept of induction can also be applied to the IM02BHR33J in the case of pulse circuit. The inductance of the coil will cause a certain amount of resistance to the current passing through, thus creating a current limiting effect.

In order to further stabilize IM02BHR33J in a larger range of temperature, an insulated core is included in the design. This can not only increase the saturation magnetic permeability, it also prevents the inductance of the windings from changing when external temperature fluctuates. Such design can increase the durability of the inductors and its overall stability.

Conclusion

In conclusion, IM02BHR33J is a kind of fixed inductors, suitable for applications like noise filters, ripple current remover or pulse circuit. Its small size and low cost make it the ideal choice in those applications which requires a minimum external dimension and temperature fluctuations compatibility.
