68 µH wirewound for DC-DC filtering and bias-T circuits
The Murata LQH32CN680K53L is a 68 µH unshielded drum-core wirewound inductor in the LQH32 series, built on a ferrite core and housed in a 1210 (3225 Metric) surface-mount package. Rated for 130 mA continuous current with a maximum DC resistance of 2.86 Ohm, the part is suited for power-supply filtering, DC-DC converter output chokes, and bias-T decoupling in low-current signal paths. The 12 MHz self-resonant frequency sits above the switching frequencies of most low-power converters, keeping the inductive impedance dominant through the operating band.
Parametric fit for a 68 µH line
Inductance is 68 µH at 1 MHz test frequency, ±10% tolerance — the value holds within 61.2 µH to 74.8 µH across the reel. Unshielded construction means the magnetic field extends beyond the body; keep a 3 mm keep-out zone from adjacent traces or ferrite beads to avoid coupling.
Board-fit and storage notes
Supplied on tape and reel (cut tape available); the reel is moisture-barrier bagged per JEDEC Level 1 — no dry-bake required before reflow if the bag seal is intact.
Active production, no cross-reference on record
No pin-compatible second source or official successor is documented; the part is single-sourced to Murata's LQH32 line.
