Frequently Asked Questions:

Q: Can I use this for LED current limiting?
A: Yes! Perfect for 20mA LEDs with 5V supply (provides ~45mA current).

Q: What’s the difference between ±5% and ±1% tolerance?
A: ±5% means actual resistance can be 95-105Ω. For precision circuits, use ±1%.

Q: Is this suitable for high-frequency circuits?
A: Carbon film resistors work well up to several MHz. For >10MHz, use metal film.

Q: How much power can it safely handle?
A: 1/4W (250mW) at 70°C. Derate for higher temperatures or better reliability.
