SMD Beads

PHILIPS COMPONENTS ferrite beads are well known components to suppress unwanted interference. These are

supplied as suppression beads to shift on a wire and as beads-on-wire for through-hole mounting on a PCB.

In response to market demands for smaller, lighter and more integrated electronic devices PHILIPS COMPONENTS

added a series of

. They are small but powerful tools for EMI/RFI attenuation in electronic equipment.

SMD beads

To our existing standarized sizes we add a new type, the

FLAT SMD BEAD ,

core that extends our range towards further miniaturization.

SMD Beads

SMD beads are available in different sizes and two suppression material grades. They are made of a ferrite tube with

rectangular cross-section and a flat tinned copper wire which is bend around the edges and forms the terminals of the

component. This design offers many superior mechanical and electrical features.

FEATURES:

Low magnetic leakage due to closed magnetic circuit

Resistant to mechanical shocks and pressure

Excellent solderability (reflow and wave soldering)

Terminals are highly resistant to pull forces

Low tolerances of mechanical dimensions enable automatic mounting

APPLICATIONS:

EMI-suppression

Decoupling

Damping of parasitic oscillations

FREQUENCY RANGE:

3S1 for frequencies up to 100 MHz

4S2 for frequencies up to 1000 MHz

(2)Width nominal (in mm)

(3)Height maximum including wire (in mm)

(4)Length nominal including wire (in mm)

(5)Material grade

ORDERING CODE (11 NC)

e.g.

4330 030 3630

The first 11 digits of the 12 NC are sufficient to order the desired SMD bead.
