Resistor 0.25W 2 ohm (10 pcs)

The Resistor 0.25W 2 ohm is a through-hole fixed resistor with a resistance of 2 Ω and a power rating of 0.25 W, sold in a pack of 10. Low values like this are used where a circuit needs a small, known voltage drop, for example to measure current, stabilise a transistor stage or add a little series resistance to a line.

Resistor 0.25W 2 ohm Specifications

• Resistance: 2 Ω, a standard E24 value
• Power rating: 0.25 W (1/4 W)
• Maximum current at full power: about 354 mA (I = √(P / R))
• Voltage drop: 0.2 V for every 100 mA flowing through it
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 10 pieces

Resistor 0.25W 2 ohm Applications

• Current sensing: read the voltage across the resistor and calculate the current with I = V / R
• Emitter resistors for stabilising small transistor amplifier and driver stages
• Small series resistors for limiting current in low-voltage circuits
• Combining in series or parallel to make other low resistance values
• Ohm's law experiments in electronics classes and STEM labs

What's in the Box

• 10 × 2 Ω 0.25 W resistors

Tip: Power rises with the square of the current (P = I² × R). This resistor reaches its 0.25 W rating at about 354 mA, so for long-term reliability keep the current below about 250 mA, where it dissipates only half its rating.
