With 120\u03a9 at 100MHz and 1.5A rated current in 0402, it effectively suppresses high-frequency noise on power and signal lines in digital circuits.","working_principle":"The BLM15E series ferrite beads use a specialized material whose impedance characteristic is dominated by resistance at high frequencies (above ~100MHz), converting noise energy into heat rather than reflecting it. This prevents resonance issues in digital circuits. The impedance remains effective into the GHz range, making it ideal for high-speed digital noise suppression.","pin_description":"
