Introduction

FBMH4532HM132-T is a low profile ferrite bead and chip designed for a wide range of applications. It is a chip-scale, low-profile package form factor, with high dynamic range, selectable combination of E/T and H/S, low frequency range and static/dynamic characteristics. FBMH4532HM132-T is capable of operating at higher voltage levels, and has the ability of connecting several differential pairs, while delivering more power. It is mainly used in mobile, tablet and consumer electronics applications, where high performance, small size, low power consumption and high frequency are required.

Application Field

As a multi-functional ferrite bead and chip, FBMH4532HM132-T is applicable in diverse areas. The chip is perfect for USB power, DC-DC converter, radio receiver, Adaptive Power Noise Filter and differential circuit applications, as well as a wide range of consumer electronic products, such as digital cameras, cellular phones, personal digital assistants (PDAs), digital audio players, and portable DVD/VCR players.

FBMH4532HM132-T is also used in mobile and tablet applications, such as Wi-Fi, Bluetooth, 3G and 4G RF receivers. In addition, the chip can be used for cable modem filters, automotive EMI filters, high speed LANs, and various high frequency power management circuits.

Working Principle

FBMH4532HM132-T works by converting electric current to a magnetic field. In the E/T field, the current passing through the coils generates a magnetic field around the chip. This magnetic field is then used to control the dielectric property of the ferrite, and its magnetic properties. In the H/S field, the current passing through the device generates a magnetic field that affects the electromagnetic energy passing through the circuit. The device can thus block or filter unwanted high frequency electromagnetic energy.

The device uses magnetic and electric currents combined with passive inductors to provide the required filtering. The chip consists of two coils connected in series, which generate a magnetic field. This magnetic field enhances the dielectric properties of the ferrite material and properly regulates the current passing through the device. This helps to reduce electric noise and dissipate high frequency electromagnetic energy.
