Ferrite Beads and Chips are electronic components used to suppress unwanted currents and electromagnetic interference or EMI. The BLM21BB050SZ1D is a ferrite bead chip that is used to perform this function. It is an example of the popular axial leaded SMT ferrite bead range.

BLM21BB050SZ1D is mainly used in RF and integrated circuits, and the application fields include medical, telecommunication equipments, audio, navigation, PCIe, automotive, consumer, and other EMI-sensitive systems. And the working principle is based on the fact that ferrite bead has a specific impedance frequency characteristic and it works like a low pass filter in the RF circuits. The working frequency of the BLM21BB050SZ1D is 10MHz to 3GHz. The chip is constructed of a sealed ceramic core (two component NiZn ferrite) with hard round plastic pins for mounting. The pins have a diameter of 0.5mm and a lead length of 4.5mm.

The chip also has a wide operating temperature range (-40 to 125°C) and it meets the IEC standards for radiation, ESD and contact current, leak current protection. It features low core losses and is widely used in interference canceling and loop breaking applications. The chip is also effective for filtering 8-12GHz signals, which is ideal for applications such as IEEE802.11 wireless LANs, Bluetooth, RFID, radar systems, GPS systems, and WiMAX.

BLM21BB050SZ1D is highly effective in noise suppression since it is designed using NiZn ferrite material and the effects of EMI are highly reduced. The chip has excellent close frequency matching that allows it to prevent frequency hopping from faster switching applications. It has a maximum operating voltage of 28V, which is suitable for regulated power supplies. The surface mount packaging makes the chip extremely compact and allows it to be placed in close proximity to sensitive circuits.

The BLM21BB050SZ1D ferrite bead chip not only has low electrical losses due to its NiZn material, but also has excellent EMI rejection capabilities. The excellent close frequency matching of the chip ensures that it is highly effective at interfering with frequency hopping signals and it has a wide operating temperature range that makes it suitable for a variety of applications. Moreover, its small size and low impedance allow for easy mounting and placement and its high tolerance power supply provides the extra safety of electrical shock protection.
