Not every workbench needs 2,000 resistors. For the hobbyist who builds a circuit every few weeks, for the student learning basic electronics, or for the engineer who just wants a small emergency stock without dedicating a drawer to resistor storage, the QUADRIOS 22P081 offers a more compact alternative: 200 metal film resistors covering 20 common values, 10 pieces of each.

The Right Amount of Inventory

The 22P081 is the smallest of the three Quadrios resistor kits. At 10 pieces per value, you can build a handful of designs — a few voltage dividers here, a few pull‑up networks there — without accumulating hundreds of unused parts. When you run out of a particular value, you know exactly which one you actually use, not which one you thought you might use someday.

Same Quality, Different Quantity

These are the same metal film resistors as the larger kits: 0.5W, 1% tolerance, ±100 ppm/°C temperature coefficient, axial leaded. The temperature range (–30°C to 150°C) is wide enough for most indoor and many outdoor applications. The 1% tolerance is critical for circuits where resistor matching matters — differential amplifiers, Wheatstone bridges, precision voltage references.

The resistor values are the same E‑series selection from 1Ω to 1MΩ as the 23P130, covering the most frequently used decades. If you need a complete set of E24 values, this kit does not cover every single step — it covers the most common ones. For professional work requiring a full inventory, the 23P130 or 22P083 would be better suited.

Who Should Buy This

Buy the 22P081 if you are just starting in electronics and do not yet know which resistor values you will use most. Buy it if you have a small desk and limited storage space — the kit comes in a compact box that fits in a drawer. Buy it if you already have a bulk supply of resistors but need a curated set of precision 1% metal film parts for specific analog designs. Do not buy it if you are building 50 units of a product and need consistent inventory across multiple production runs — the 23P130 or bulk reels would be more appropriate.
