Other Resistors Q & A
Here are answers to common questions about Other Resistors:
Q: What’s the difference between thick film and thin film resistors?
A: Thick film resistors are cheaper and used in general applications, while thin film resistors offer higher precision for sensitive circuits.
Q: How do I calculate the power rating needed for my resistor?
A: Use the formula P = I²R, where P is power, I is current, and R is resistance.
Q: Can I use a fusible resistor as a regular resistor?
A: Yes, but it’s designed to fail under overload, so it’s best used in protective circuits.
Q: Are Chinese resistors reliable?
A: Many Chinese suppliers produce high-quality resistors, but always verify certifications and test samples.
Q: What’s the typical tolerance for industrial resistors?
A: Industrial-grade resistors usually have a tolerance of ±1% to ±5%.
