Between the 200‑piece starter kit and the 2,000‑piece bulk box lies the 1,000‑piece sweet spot. The QUADRIOS 22P083 gives you 50 pieces of each of 20 resistor values — enough to run a small production batch of 25 boards twice over, but not so many that you feel guilty when a particular value sits unused for years.

Why 50 Pieces per Value

For a small electronics lab, 50 pieces of a resistor value is a practical amount. You can populate ten boards (each using five of that value) and still have spares for prototyping. If a value is rarely used, 50 pieces occupy minimal storage. If a value is heavily used, 50 pieces provide a buffer while you order a full reel. The 22P083 is the kit you keep on the shelf for everyday work, with the understanding that you will replenish specific values as needed.

Real‑World Usage Example

Consider a simple microcontroller board with an LED indicator (220Ω current limiting), I²C pull‑ups (4.7kΩ), a voltage divider for analog input (10kΩ and 100kΩ), and a reset pull‑up (10kΩ). A single board uses four resistor values: 220Ω (1 piece), 4.7kΩ (2 pieces), 10kΩ (2 pieces), 100kΩ (1 piece). With 50 pieces of each, the kit supports roughly 25 boards before any value runs out. For a small consulting project or a limited production run, that is exactly the right scale.

Same Specifications as Larger Kits

Like its siblings, the 22P083 uses metal film construction with 1% tolerance and a ±100 ppm/°C temperature coefficient. The 0.5W power rating is sufficient for signal‑level circuits and light loads. The axial leaded package fits standard 0.1‑inch perfboard and breadboard spacing, with leads that are easily formed and soldered.

The resistor values are drawn from the E‑series decades covering 1Ω to 1MΩ, prioritizing the values most commonly used in analog and digital design: 1Ω, 10Ω, 100Ω, 220Ω, 330Ω, 470Ω, 1kΩ, 2.2kΩ, 4.7kΩ, 10kΩ, 22kΩ, 47kΩ, 100kΩ, 220kΩ, 470kΩ, 1MΩ, and several others in between.

Choosing Between the Three Kits

Choose the 22P083 (1,000 pieces, 50 per value) if you are a professional or semi‑professional working on small to medium projects, running low‑volume production, or managing a shared lab inventory. Choose the 23P130 (2,000 pieces, 100 per value) if you need the security of larger quantities or share a kit across multiple engineers. Choose the 22P081 (200 pieces, 10 per value) if you are a hobbyist or occasional builder who values variety over depth.
