  • Chip Multilayer Bead Inductors (TRMB Series)

About Using Multilayer Chips:

Chip Beads, perform the function of removing RF energy that exists within a transmission line structure (Printed circuit board tracking). This RF energy is an AC sine wave component that co-exists with the DC voltage level of the transmitted signal. The DC component is the intended signal of interest whereas RF energy will propagate down the trace and radiate as EMI.

Beads perform the function of being a high frequency resistor (attenuator) allowing DC energy to pass through whilst removing AC energy.

Chip Beads consist of a soft ferrite material which responds to RF energy. This material contains high resistivity in monolithic form. Eddy current losses are inversely proportional to resistivity. These losses increase with the square of the frequency. The eddy currents are the RF energy that travels through the device.

Hard ferrite is associated with a permanent magnetic field, its polarities become fixed as North and South. Soft ferrite material will change its impedance value based on the frequency that the bead presents to the circuit and does not permanently retain the magnetic field.

A Selection Guide To Miniature Ferrite Chip Beads:

TRMB100505, TRMB160808, TRMB201209, and TRMB321611 Series
covers a wide range of impedance characteristics.
It is designed to prevent electromagnetic interference.

TRMB100505-YTRYN060, TRMB100505-YTRQN060, TRMB160808-YTRYN060, TRMB160808-YTRQN060, TRMB321611-YTRYN080, and TRMB201209-YTRQN050 Series can be used in high current circuits due to its low DC resistance.

TRMB100505-YTRQN060, TRMB160808-YTRQN060, TRMB201209-YTRQN050,
and TRMB321611-YTRQN150 Series can minimize attenuation of the signal wave form due to its sharp impedance characteristics.
Those are designed for high speed applications. Those series generates an impedance down to relatively low frequency.

Advantages Of Using Multilayer Chips:
  • Suitable to high density printed circuit boards.
  • Perfect shape for automatic mounting, with no directionality.
  • Monolithic inorganic material construction for high reliability.
  • Outstanding soldering heat resistance. Both flow and reflow soldering methods can be used.
  • Small size chips generate high impedance. Minimum floating capacity and excellent high frequency characteristics.
