BLM18HE152SN1D
Category
The Murata BLM18HE152SN1D is a 0603 package ferrite bead designed for EMI filtering with 500mA current rating, 500mΩ DC resistance, and 1.5kΩ impedance @ 100MHz. It is ideal for compact consumer electronics and automotive systems requiring robust noise suppression. Critical design parameters include thermal management (10°C/W), soldering precautions (300°C max), and voltage limits (50V DC). Market strengths include brand reliability and compact form factor, while limitations involve higher cost and stock availability. Proper placement near noise sources and thermal vias are recommended for optimal performance.
