The 220K ohm, 1/4 Watt Resistor (5% tolerance) is an essential component in electronic circuits, providing precise resistance to control current flow. With its 5% tolerance, it ensures accuracy in resistance values, making it ideal for a wide range of applications, from hobbyist projects to industrial electronics. Its compact size and high reliability make it a go-to choice for engineers and enthusiasts seeking stable performance in their designs.
Key Features
- 220K ohm resistance: Precise resistance value for controlling current.
- 1/4 Watt power rating: Suitable for low-power applications.
- 5% tolerance: Ensures accuracy in resistance values.
- Compact size: Easy integration into circuit designs.
- High reliability: Provides stable performance in various environments.
Precautions
- Avoid exceeding power rating to prevent overheating.
- Handle with care to prevent damage to the resistor’s leads.
- Ensure proper soldering techniques to maintain electrical connections.
- Keep away from moisture and contaminants to prevent corrosion.
- Check datasheet for voltage limitations to avoid breakdown under high voltages.
Frequently Asked Questions (FAQs)
Question: What does the 5% tolerance mean?
Answer: It indicates that the actual resistance of the resistor can vary by up to 5% from the specified value of 220K ohms.
Question: Can I use this resistor in high-power applications?
Answer: No, it’s rated for 1/4 Watt power, suitable for low-power applications only.
Question: How do I determine the wattage rating for my circuit?
Answer: Calculate the power dissipation using the formula P = V^2 / R, where V is the voltage across the resistor and R is its resistance.
Question: Can I trim this resistor’s value if needed?
Answer: No, it’s a fixed-value resistor and cannot be adjusted.
Question: Is this resistor suitable for temperature-sensitive environments?
Answer: Yes, it has good stability over a wide temperature range, but extreme temperatures should still be avoided.
