At 650 mA the copper loss is 63 mW, which is manageable in a 1210 package but will raise the temperature above ambient. Unshielded drum-core construction means the magnetic field extends beyond the part body. Keep this inductor at least a part-width away from sensitive analog traces or RF signal paths on the same layer. Self-resonant frequency is 43 MHz, well above the typical 500 kHz to 2 MHz switching frequency of a buck converter using a 4.7 µH inductor — no risk of the inductor self-resonating in-band. ## Footprint and rework reality 1210 (3225 metric) nonstandard package — the 'nonstandard' label just means it's a drum-core wirewound in a standard 1210 chip footprint. The pad layout is the same as any 1210 ceramic capacitor, so no special footprint work. Unshielded construction means you can see the winding through the coating — useful for visual orientation during hand placement. The ferrite core is brittle; don't lever the part off the pad or you'll crack the drum. Standard industrial temperature grade — fine for most indoor electronics, but not for under-hood or high-temp environments.","metaTitle":"Murata LQH32CH4R7M53L 4.7 µH Inductor, 650 mA, 1210","metaDescription":"Murata LQH32CH4R7M53L wirewound drum-core inductor, 4.7 µH ±20%, 650 mA, 150 mOhm DCR, unshielded, 1210 footprint.

For a power inductor in a buck or boost converter, the tolerance is less critical than the saturation current — the control loop compensates for the inductance spread. But if you're using this in a resonant tank or filter, the 20% band may be too wide."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH32CH4R7M53L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH32CH4R7M53L when reusing this data.
