Resistor 0.5W 4.7K ohm (5 pcs)

The Resistor 0.5W 4.7K ohm is a through-hole fixed resistor with a resistance of 4.7 kΩ and a power rating of 0.5 W, sold in a pack of 5. 4.7 kΩ is the standard pull-up value for I2C bus lines (SDA and SCL) and for the data line of DS18B20 temperature sensors, and it is also a common base resistor for small transistors.

Resistor 0.5W 4.7K ohm Specifications

• Resistance: 4.7 kΩ (4,700 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 4.7K ohm Applications

• Pull-up resistors for I2C SDA and SCL lines
• Pull-up resistor for DS18B20 and other 1-Wire sensors
• Base resistors for NPN transistors such as the BC547 or 2N2222
• Voltage dividers and biasing circuits
• Electronics education and prototyping

What's in the Box

• 5 × 4.7 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. For a DS18B20, connect the 4.7 kΩ resistor between the data pin and VCC. With 4.7 kΩ the 0.5 W limit is reached at about 48 V across the resistor.
