The BLM18PG181SN1D is a ferrite bead manufactured by Murata. It has a compact 0603 profile and is ideal for EMI suppression in communication circuits and power supply lines. The bead is made of high-frequency noise absorbing material and features a resistive component consisting of a 180 ohm resistance value. It also has a low DC resistance, allowing it to effectively block high-frequency noise without attenuating the desired signal. The component is capable of withstanding high temperature, making it suitable for use in high-temperature environments. It has an operating temperature range of -55C to +125?. The component is a cost-effective and efficient way to reduce EMI interference and enhance the reliability of circuits.
