Inductor 680uH

The Inductor 680uH is a fixed inductor with an inductance of 680 µH (0.68 mH). It stores energy in its magnetic field and resists fast changes in current, so it is used to filter supply lines, block high-frequency signals and build LC filters. It suits power-supply repair, audio and radio projects, and electronics education.

Inductor 680uH Specifications

Inductor 680uH Applications

• Filtering ripple and noise on DC power lines
• RF chokes that pass DC but block radio frequencies
• LC low-pass and band-pass filters
• Energy storage in low-current DC-DC converters
• Electronics classes and experiments with LC circuits

What's in the Box

• 1 × 680 µH inductor

Tip: Check that the current in your circuit stays within the inductor's rating: if the current is too high the core saturates, the inductance drops and the coil can overheat. Measure the part with an LCR meter if you need an exact value for a filter.
