Frequently Asked Questions

What is the voltage limit for a 100K 0.25W resistor?

With a 0.25 W rating and 100K Ω resistance, the maximum continuous voltage is approximately 158 V (V = √(P×R)), assuming proper cooling and ambient conditions.

How do I read the color code Brown-Black-Yellow-Golden?

The first band “Brown” is 1, second “Black” is 0, the third “Yellow” is multiplier 10^4, giving 10 × 10^4 Ω = 100,000 Ω, and the “Golden” band indicates ±5% tolerance.

Can I use these resistors for high-precision circuits?

These carbon film resistors offer ±5% tolerance, suitable for general-purpose applications. For higher precision, consider metal film resistors with tighter tolerance.
