Inductor Kits
An SMD inductor kit puts a full ladder of inductance values on the bench, sorted and labelled. Use one when you are tuning a filter, bringing up a switching converter or matching an RF stage and the value changes several times before the circuit settles. Inductors are the part people most often have to try three of before one works, which is exactly what a kit is for.
ATI stocks three kits — 0402, 0805 and 1008 — holding 60 to 85 values each, in 20, 50 or 100 pieces per value, from $98. Every kit comes in a case with individually lidded, labelled bins. Quantities on hand are limited and shown live in the table below.
The kits
Three package sizes, three quantity options each. Match the package to your boards first — that decides it in most cases — then pick how deep you want each bin stocked. Part numbers read straight off those two choices: L0805-85VALUE-100PC is the 0805 kit, 85 values, 100 pieces of each.

Which kit do I need?
Package size decides this in most cases. If your boards use a size we do not stock, one of the neighbours may still be worth having on the bench for breadboard and rework use.
| Kit | Package | Values | Pieces per value | Price | Choose this if… |
|---|---|---|---|---|---|
| L0402-74VALUE 74 values | 0402 | 74 | 20, 50 or 100 | $98–$321 | You build dense boards and your inductors are signal-path parts — filters, matching networks, small-signal work. |
| L0805-85VALUE 85 values, widest ladder | 0805 | 85 | 100 | $388 | You want the most values in one box. 0805 is the general bench compromise — small enough for real boards, still workable with tweezers. |
| L1008-60VALUE 60 values | 1008 | 60 | 20, 50 or 100 | $108–$308 | You are working on power conversion rather than signal paths. The larger body carries more current and handles more power. |
Worth knowing
- L0805-85VALUE-100PC reads as: 0805 package, 85 values, 100 pieces of each. The 0402 and 1008 kits offer 20, 50 and 100 piece options; the 0805 kit is stocked in the 100 piece configuration.
- Package size is about current, not just space. A 1008 part has a larger core and thicker winding than an 0402, so it carries more current before it saturates. That is why the 1008 kit suits power work and the 0402 kit suits signal work, even where both cover similar inductance values.
- Every value has its own lidded, labelled bin. This matters more with inductors than with resistors or capacitors, because most SMD inductors carry no marking at all — once a part is loose on the bench, nothing on it tells you what it is.
Why buy these from ATI
- Every value in its own lidded bin — Each bin opens on its own and carries a printed label. With unmarked parts that is not a convenience, it is the only thing standing between you and a box of anonymous components.
- Published prices, from $98 — No quote request and no account setup. What you see is what it costs.
- Ships from San Jose — In stock now, out the door in a day or two.
- The rest of the bench too — Resistor and capacitor kits use the same cases and the same labelling.
Who buys these
Switching converter development
The output inductor is the part you are most likely to change during bring-up, and the one whose value the datasheet calculation gets only approximately right.
Filter and RF matching work
Matching networks and LC filters are fitted, measured and refitted. Having the neighbouring values in the box is what makes that an afternoon rather than a week.
Repair and rework
Board-level repair, where the failed part is unmarked and you need to match a value read off a schematic or measured on a good board.
Teaching and lab benches
Shared benches where a labelled, lidded bin is the difference between a usable stock and a drawer of unidentifiable parts.
Frequently asked questions
Isat or Irms — which current rating should I design to?
Both, for different reasons. Irms is the current that heats the part to its temperature limit, so it governs continuous operation. Isat is the current at which the core begins to saturate and the inductance falls away — often sharply. In a switching converter the peak current, including ripple and any startup surge, must stay below Isat, while the average current must stay below Irms. A design that respects only the average figure can saturate on every switching cycle and still look fine on a multimeter.
Why do inductors have such wide tolerances compared with resistors?
Inductance depends on core material and winding geometry rather than on a trimmed film, and core permeability varies from batch to batch and with temperature. ±20 % is normal for a power inductor and tighter grades exist for signal work. The practical consequence is that circuits should be designed to tolerate the spread rather than assume the marked value — and it is another reason a kit earns its place, since the value you calculated and the value that works are often one step apart.
Shielded or unshielded — does it matter?
It matters when the inductor sits near something sensitive. An unshielded part radiates its field into the surrounding board, which can couple into high-impedance nodes, analog front ends or nearby inductors. A shielded part contains most of that field at the cost of a little size and price. In a converter tucked away in a corner, unshielded is usually fine. Next to an ADC input or a feedback node, it usually is not.
Which package should I take for a general-purpose bench?
0805, if your work is mixed. It is small enough to fit real layouts, large enough to handle with tweezers, and the 85-value kit is the widest ladder we stock. Take 0402 if your boards are dense and your inductors are in signal paths; take 1008 if you spend your time on power conversion and need the current handling that a larger body gives you.
