Frequently Asked Questions

How many resistors come in this pack?

This offering includes 100 pieces of 1M Ω 0.25W carbon film resistors, suited for both prototyping and production runs.

What does the color code Brown-Black-Yellow-Gold indicate?

The first two bands (Brown, Black) form “10,” the third band (Yellow) is the multiplier ×10⁴, yielding 1,000,000 Ω. The Gold band denotes a ±5% tolerance.

Is the 0.25W power rating sufficient for my design?

At 0.25 W, these resistors are designed for low-power applications. To avoid damage, maintain operating current below approximately 0.5 mA or use multiple resistors in parallel for higher dissipation.
