BLM18KG331SH1D

BLM18KG331SH1D is a surface‑mount ferrite bead from TDK’s BLM18 family. It is used to suppress high‑frequency EMI/RFI on power rails and data lines, while passing DC. The “331” code means about 330 ohms of impedance at 100 MHz; DC resistance is very low. The device comes in an 1812/4.6×3.2 mm package suitable for reflow soldering and is designed for typical consumer and industrial electronics. It helps filter noise in applications such as motherboards, USB/HDMI lines, and other high‑speed interfaces. For exact current rating, temperature range (-40 to +125°C), and impedance vs. frequency curves, refer to the official BLM18KG331SH1D datasheet.

Do you want cross‑manufacturer part numbers or just equivalent specs? Generally the equivalent is any 0603 ferrite bead with 330 Ω impedance at 100 MHz, same DC current rating and package. Common manufacturers with matching parts: TDK, Taiyo Yuden, Würth Elektronik and Murata (other series). Reply and I’ll fetch exact cross‑reference part numbers.
