RF Chip Multilayer Bead Inductors (TRMB)

RF Chip Multilayer Bead Inductors (TRMB)

Direct RF inductor chip multilayer bead offer high impedance for high speed signals. Direct Electronics has introduced the (TRMB) Series, a family of twelve multilayer chip bead inductors offering high impedance. The (TRMB) Bead series is a multilayer technology with good overall characteristics in a cost effective package. In addition, (TRMB) parts offer a high-performance noise-filtering capability over a wide range of high frequencies.

In systems that currently use multiple narrow-band inductors to cover a wide frequency range, the (TRMB) can provide the same function in a single chip, reducing component count and board area. The (TRMB) multilayer inductor series is available in 1812, 1806, 1210, 1206, 0805, 0603, and 0402 sizes in three catalogs, standard, low profile, and High Speed Signals. This product provides a good addition of electrical performance and low cost.

Direct Multilayer Bead RF Inductor (TRMB) series is primarily designed for effective EMI protection and low dc resistance. Full series conform to the RoHS directive and Lead-free. Multilayer Bead Chip Inductor with wide inductance selection and impedance can be customed designs and tighter tolerances available on request.

Application of specific designs also available including different factor values to frequency requirements. Custom parts are available on request. Direct will also produce devices outside these specifications to meet specific customer requirements,
