Resistor 0.25W 4.7K ohm (10 pcs)

The Resistor 0.25W 4.7K ohm is a through-hole fixed resistor with a resistance of 4.7 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. It is one of the most used values in microcontroller projects: it is the usual pull-up resistor for I2C buses and for the data line of the DS18B20 temperature sensor. It is also handy for transistor bases and voltage dividers.

Resistor 0.25W 4.7K ohm Applications

• Pull-up resistors for I2C SDA and SCL lines
• Pull-up for the 1-Wire data line of DS18B20 temperature sensors
• Base resistors for small transistors
• Voltage dividers for analog inputs
• Electronics education and prototyping

What's in the Box

• 10 × 4.7 kΩ 0.25 W resistors

Tip: For I2C, connect one 4.7 kΩ resistor from SDA and one from SCL to the bus supply (3.3 V or 5 V); many breakout modules already include pull-ups, so check before adding more. With 4.7 kΩ, the 0.25 W limit is reached at about 34 V across the resistor.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
