Chip Multilayer Ferrite Inductors (TRMI)

New options in chip multilayer ferrite inductor. DeMint (TRMI) series is a multilayer ferrite technology with good overall characteristics in a cost effective package. The (TRMI) multilayer inductor series is available in 0603, 0805, and 1206 sizes. Inductance values range from 10 to 33000nH, and tolerances are as tight as ±10%. This product provides a good blend of electrical performance and low cost.

The (TRMI) devices utilize closed magnetic circuit construction to avoid crosstalk. These are suitable for EMI reduction on DC power lines and low speed signal lines where the smaller packaging reduces board space. Conform to the RoHS directive and Lead-free. Package of multilayer Ferrite TRMI chip is suitable for automatic pick and place equipment and is mounted in a surface mount package which assures mechanical stability and excellent lead coplanarity.

Multilayer Ferrite RF Chip Inductor can be customed designs and tighter tolerances available on request. Application of specific designs also available including different inductance values and Q specifications adjusted to frequency requirements.

Custom parts are available on request. DeMint will also produce devices outside these specifications to meet specific customer requirements,
please contact our sales for more information. Download complete specification RF Chip Inductors (TRMI) PDF (407KB).
