Key Features

The BLM15AG221SN1D from Murata is a compact surface-mount ferrite bead designed for effective noise suppression across a broad frequency range, particularly from 30 MHz to several hundred MHz. With an impedance of 220 Ω at 100 MHz and a rated current of 450 mA, it efficiently attenuates high-frequency noise while maintaining signal integrity. The component’s low DC resistance of 0.29 Ω minimizes power loss, enhancing overall circuit efficiency. Its 0402 package size allows for seamless integration into high-density PCB layouts. The BLM series is engineered to function nearly as a resistor at noise frequencies, reducing the possibility of resonance and preserving signal waveforms. The nickel barrier structure of the external electrodes provides excellent solder heat resistance, ensuring durability during assembly processes.

Applications

Noise suppression in digital interfaces of consumer electronics to ensure signal clarity.
EMI filtering in medical equipment, excluding implant, surgery, and auto-injector devices, to maintain device reliability.
Reduction of high-frequency interference in industrial equipment, excluding transportation, facility, and energy equipment, to enhance operational stability.
Attenuation of electromagnetic noise in communication devices to improve performance.
Enhancement of signal integrity in automotive infotainment systems by suppressing unwanted noise.

Product Overview

Murata’s BLM15AG221SN1D ferrite bead is specifically designed to provide effective noise suppression in electronic circuits without the need for a connection to ground, making it suitable for applications lacking stable ground lines. Its compact 0402 size and surface-mount design facilitate easy integration into space-constrained PCB layouts. The component operates reliably over a wide temperature range from -55°C to +125°C. Thus ensuring consistent performance in various environmental conditions. The BLM series’ design effectively reduces the possibility of resonance, preserving the integrity of signal waveforms. Additionally, the nickel barrier structure of the external electrodes offers excellent solder heat resistance, contributing to the component’s durability during assembly processes. This ferrite bead is an ideal choice for designers seeking efficient and reliable noise suppression solutions in consumer electronics, medical devices, and industrial equipment.
