Description
A 47 ohm resistor with a power rating of 1/4 watt is a common electronic component used in various electronic circuits. Here are the key details:
1. **Resistance Value:** 47 ohms represents the resistance value of the resistor. The resistance is 47 ohms.
2. **Power Rating:** 1/4 watt indicates the power rating of the resistor. This means the resistor can safely dissipate up to 0.25 watts of power without overheating. The power rating is important to ensure that the resistor can handle the electrical energy passing through it without damage.
3. **Tolerance:** The tolerance is not specified in your request, but resistors typically have a tolerance value that indicates the range within which the actual resistance can deviate from the specified value. Common tolerance values include 1%, 5%, and 10%.
4. **Physical Size:** 1/4 watt resistors are relatively small in size. They can be through-hole resistors with axial leads, making them suitable for soldering onto a circuit board or breadboard.
5. **Application:** 47 ohm resistors are used in various electronic circuits for purposes such as current limiting, voltage division, and biasing.
When working with resistors, it’s important to respect their power ratings and choose resistors that can handle the expected power dissipation in the circuit. If the power exceeds the specified wattage, the resistor may overheat and be damaged. Additionally, the color code on the resistor’s body can be used to verify its resistance value and tolerance.
