Multilayer Ferrite Bead Inductors (TRMA)

DeMint High Current Multilayer Ferrite Bead Inductors lower DC resistance and handle up to 6A. DeMint TRMA series multilayer ferrite bead SMD inductor is one popular high current version of DeMint chips products. Ceramic materials and process technologies have allowed DeMint to lower the DC resistance of its chip ferrite beads, increasing rated current to create the TRMA series.

With a maximum current rating of up to 6A and a wide operating temperature range of between -55°C and +125°C, the TRMA series is ideally suited to applications in harsh environments. The series comes in 0402 size packaging (1 x 0.5 x 0.5 mm), for designers seeking to reduce board space without performance degradation. Low DC resistance also helps reduce power consumption for battery-powered applications.

The TRMA devices give effective EMI and RFI suppression and the range also offers high impedance values over a wide frequency range. Quoted reference values are between 7Ω and 1500Ω at 100MHz. Available in case sizes ranging from 0402, 0603, 0805, 1206, 1210, 1806, to 1812, the ferrite chip beads feature nickel barrier terminations with a solder plate finish to help ensure a good solder joint. Parts are supplied taped and reeled, and are fully compatible with automatic pick and place equipment.

Custom parts are available on request. DeMint will also produce devices outside these specifications to meet specific customer requirements,
