Product details

Parametric fit for a power rail

The LQH32CH4R7M53L: 4.7 µH at 650 mA with 150 mOhm DCR — the DC resistance is the number that governs self-heating at full load, not just the current rating. 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.

Frequently asked questions

What is the inductance tolerance and what does it mean for my circuit?

Tolerance is ±20%. 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.
