Product Description
Product Overview
The BLM18EG121SN1# series from Murata is a range of chip beads designed for noise suppression. These components feature a modified internal electrode structure to minimize stray capacitance and extend the effective frequency range. The BLM18E series specifically offers low DC resistance and high rated current, making it suitable for driver circuit noise suppression. Its thin profile (0.5mm) is ideal for compact and low-profile devices like DSCs and cellular phones. The magnetic shielded structure minimizes crosstalk.
