Copper drum-coil inductor on an 8×12 mm core for filtering and energy storage in compact assemblies.
Core: 8×12 mm drum
View specificationShielded drum-core inductor around 33 µH for compact DC-DC stages where EMI from an open drum is unacceptable.
Inductance: 33 µH class
View specificationMedium size 10x12 drum core inductor. Offers a good balance of inductance and current rating.
Inductance: 3.3uH - 52.0uH
View specificationLarge 12x15 drum core inductor for higher power applications requiring significant energy storage.
Inductance: 3.0uH - 120uH
View specificationSmallest drum core inductor in the range, for compact assemblies where a few hundred milliamps is the whole budget.
Inductance: 1.0uH - 10uH
View specification5 x 7mm drum core inductor for general-purpose filtering on space-constrained boards.
Inductance: 2.2uH - 12.0uH
View specificationCompact 6x8 drum core inductor with shrink sleeve. Ideal for general purpose filtering and energy storage.
Inductance: 3.3uH - 13.0uH
View specification8 x 10mm drum core inductor, a step up in current handling while staying through-hole.
Inductance: 3.3uH - 33.0uH
View specificationShielded surface mount drum inductor, the core encapsulated in ferrite resin to close the magnetic path. Choose this over the unshielded part when the inductor sits near an antenna, an ADC or anything else that will pick up the field.
Inductance: 1.0uH - 1000uH
View specificationUnshielded surface mount drum inductor. Leaving the core open lets it carry a higher peak current before saturating and costs less than a shielded part, which is the right trade wherever the surrounding circuitry tolerates the stray field.
Inductance: 1.0uH - 1000uH
