BLM15AG121SN1D Description

Short technical summary and product information.

The BLM15AG121SN1D is a chip ferrite bead from Murata's BLM15_SN series. It offers a nominal impedance of 120 Ω at 100 MHz, a maximum DC resistance of 190 mOhm (typical), and a rated current of 550 mA at 85°C ambient (450 mA at 125°C). This single-line ferrite bead is designed for noise suppression in power supply lines and signal lines across a wide range of applications.

 

Key specifications include an operating temperature range of -55°C to +125°C, making it suitable for harsh environments. The component is housed in a standard 0402 (1005 Metric) surface-mount package with dimensions 1.00mm x 0.55mm x 0.55mm (max).

 

According to the manufacturer's datasheet, this ferrite bead is applicable in consumer equipment, industrial equipment, medical equipment (GHTF Class C and A/B), and power equipment such as renewable energy and EV charging systems. It is not intended for applications where failure could directly cause harm to life or property.

 

Packaging is Tape & Reel (D suffix), suitable for automated assembly processes.
