BLM15AX121SN1D Description

Short technical summary and product information.

The Murata BLM15AX121SN1D is a chip ferrite bead designed for noise suppression in various electronic circuits. It offers a typical impedance of 120 Ω at 100 MHz, with a maximum DC resistance of 130 mΩ and a rated current of 700 mA. The component is housed in a compact 0402 surface-mount package measuring 1.00 mm x 0.55 mm with a maximum height of 0.55 mm.

 

This ferrite bead operates over a wide temperature range of -55°C to +125°C, making it suitable for demanding environments. It is a single-line device, ideal for filtering power lines or signal lines where space is constrained. The BLM15_SN series is specified for consumer, industrial, and certain medical equipment applications.

 

The surface-mount design allows for automated assembly, and the small footprint enables high-density PCB layouts. The component is RoHS-compliant and lead-free, though explicit RoHS certification data is not provided in the available documentation.
