BLM18RK121SN1D Description

Short technical summary and product information.

The Murata BLM18RK121SN1D is a chip ferrite bead designed for noise suppression in consumer and industrial equipment. It offers a nominal impedance of 120 Ohm at 100 MHz, with a maximum DC resistance of 250 mOhm and a rated current of 200 mA at 85°C ambient temperature. The component operates over a temperature range of -55°C to +125°C.

 

This ferrite bead is housed in a standard 0603 (1608 metric) surface-mount package with dimensions of 1.60 mm x 0.80 mm and a maximum height of 0.95 mm. It is supplied in tape-and-reel packaging with 4000 pieces per reel. The part is suitable for a wide range of applications including power supply lines, signal lines, and general-purpose filtering in consumer electronics, industrial control systems, and medical equipment (GHTF Class A/B/C).

 

With a single-line configuration, this ferrite bead provides effective high-frequency noise attenuation while maintaining low DC resistance to minimize power loss. The component is designed for surface-mount assembly and is compatible with standard reflow soldering processes.
