The notation “4.7E 1/4W” for a resistor can be broken down as follows:
- 4.7E: This represents the resistance value of the resistor, which is 4.7 ohms. The “E” is often used in place of a decimal point in electronic notation.
- 1/4W: This indicates the power rating of the resistor, which is 1/4 watt (0.25 watts). This means the resistor can safely dissipate 0.25 watts of power without being damaged.
In summary, a resistor labeled “4.7E 1/4W” has a resistance of 4.7 ohms and can handle up to 0.25 watts of power.
Product Details
A 4.7kΩ (4.7 kilo-ohms) 1/4W resistor has several key features:
- Resistance Value: 4.7kΩ, which means it resists the flow of current by 4,700 ohms.
- Power Rating: 1/4 watt (0.25W), indicating the maximum power it can dissipate without damage.
- Tolerance: Typically ±5%, meaning the actual resistance can vary by 5% from the nominal value.
- Type: Often a carbon film or metal film resistor, which affects its stability and noise characteristics.
- Temperature Coefficient: Indicates how the resistance changes with temperature, usually specified in parts per million per degree Celsius (ppm/°C).
