2.2 µH wirewound for power-line filtering
The Murata LQH32CN2R2M53L is a 2.2 µH drum-core wirewound inductor in the LQH32 series, rated for 790 mA continuous current with a maximum DC resistance of 126.1 mOhm. The unshielded construction means the magnetic field radiates outside the core — keep it away from sensitive traces or other magnetics on the board, or budget for a shielded part if crosstalk shows up in the first spin. The self-resonant frequency sits at 64 MHz, so this inductor behaves as an inductor well past the switching frequencies of most buck converters (typically 500 kHz to 2 MHz) and into the HF band. Above 64 MHz the impedance turns capacitive — not a problem for power rails, but worth noting if you are using it as an RF choke in the 100 MHz range.
Board-fit and temperature envelope
The ±20% tolerance on the 2.2 µH value is typical for power-grade wirewounds — the saturation current is not listed here, so for a buck converter running near the 790 mA limit, verify the inductor does not saturate at the peak current (usually 1.2× to 1.5× the DC rating) by checking the Murata datasheet's saturation curve.
Sourcing and compliance
Supplied in Tape & Reel (TR) or Cut Tape (CT) — the standard reel quantity for 1210 inductors is typically 2,000 pieces, but confirm the exact pack size at quote.
