Resistor 0.5W 2K ohm (5 pcs)

The Resistor 0.5W 2K ohm is a through-hole fixed resistor with a resistance of 2 kΩ and a power rating of 0.5 W, sold in a pack of 5. Paired with a 1 kΩ resistor it forms the classic divider that drops a 5 V signal to about 3.3 V, so it is handy for connecting 5 V sensors to ESP32 and Raspberry Pi inputs.

Resistor 0.5W 2K ohm Specifications

• Resistance: 2 kΩ (2,000 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 2K ohm Applications

• Voltage dividers, such as 1 kΩ + 2 kΩ to read the 5 V echo pin of an HC-SR04 with a 3.3 V board
• Current limiting for dim indicator LEDs
• Pull-up and pull-down resistors for logic inputs
• Biasing transistors and op-amp circuits
• Electronics education and prototyping

What's in the Box

• 5 × 2 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. In a 5 V to 3.3 V divider, put the 1 kΩ resistor on the signal side and the 2 kΩ resistor to ground. With 2 kΩ the 0.5 W limit is only reached at about 31 V, so it is very safe for 3.3 V, 5 V and 12 V circuits.
