Token inductor chip multilayer bead
offer high impedance (TRMB)
Preview
Token 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.
Token Multilayer Bead 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. Token will also produce devices outside these specifications to meet
specific customer requirements,
please contact our sales for more information.
