Small axial inductors (4 × 10 mm) that look like resistors and are read the same way, in µH. Each value comes on a labelled tape strip. Use them for LC filters, supply decoupling, small DC-DC experiments and RF tuned circuits.

Plus 200 female crimp terminals for the housings and 200 male pins (as listed by the supplier), on reels. 2.5 mm pitch, fits standard 2.54 mm boards; the polarised shroud stops a plug going in backwards. The common connector for battery balance leads, fans and small modules; crimping needs a crimp tool for JST-XH style terminals.

Good to know

  • Always replace a fuse with the same current rating, speed and voltage rating as the original. Fuses in mains equipment are only for people qualified to work on it.
  • The potentiometer, LED, connector and fuse boxes keep their compartment boxes; the inductors come on taped strips in a bag.
  • Heavy item: about 0.85 kg packed, so the price includes a $5 weight surcharge towards international postage (the same surcharge applies to each pack you order).
  • Parts are bagged and labelled by value or part number and packed by hand by our supplier, so a bag can occasionally hold a few pieces more or less than listed, or a close substitute value. Some bag labels are printed in Chinese next to the part numbers.
  • Contains small parts. Not a toy; keep away from young children.

Shipping

Standard shipping: $9.00 for the first item, +$1.80 for each additional item. Free shipping on orders over $260.

We ship worldwide, by default with economical international post (UPU / China Post small packet) to keep shipping costs low. Orders are usually handed to the carrier within 2–5 business days, and economical international post then takes about 10–30 business days to arrive; these are estimates, not guarantees. Delivery time depends on the destination and on postal and customs handling. If you need your order by a certain date, email us before ordering: faster shipping can be arranged, with the extra cost charged at the carrier's actual rate. Items that contain batteries or magnets are marked on their product page and ship by a special carrier line; some countries and regions cannot be reached by that line, and if yours is one of them we refund the order in full.

Customs & duties

Import duties, taxes and customs requirements depend on the destination country, the shipping route and the local customs office, so we cannot say in advance whether any will apply to your parcel. Customs may hold a parcel, ask for more information, or ask for duties or taxes to be paid, even when the declared value is correct. If you have a question about your country, email us before ordering.
