20PCS 4.7 OHMS 4 BAND RESISTOR 1/4 WATT

🔹 20pcs 4.7 Ohm (4R7) 4-Band Resistor – 1/4 Watt Carbon Film

This value pack contains 20 high-quality 4.7 ohm (marked as 4R7) resistors, ideal for low-resistance applications such as current sensing, LED balancing, and emitter degeneration. With a power rating of 1/4 watt and ±5% tolerance (gold band), these reliable 4-band carbon film resistors are essential for any electronics workbench.

✅ Specifications:

• Resistance: 4.7 Ohms (Ω) / 4R7

• Type: 4-Band Carbon Film Resistor

• Power Rating: 1/4 Watt (0.25W)

• Tolerance: ±5% (Gold Band)

• Band Colors: Yellow, Violet, Gold, Gold

• Quantity: 20 Pieces

• Package: Convenient storage strip

⚠️ Important Power Note:
At 4.7Ω, these resistors will draw significant current. For example:

• At 3V: Current ≈ 0.64A → Power ≈ 1.9W (exceeds 1/4W rating)

• At 5V: Current ≈ 1.06A → Power ≈ 5.3W (far exceeds rating)

Always verify your circuit current using I²R or V²/R before use. These are suitable only for very low-voltage or low-current applications.

📦 Applications:
✔️ Current sensing and limiting (low-current only)
✔️ LED balancing in parallel arrays
✔️ Emitter degeneration in transistor circuits
✔️ Low-value timing networks
✔️ Snubber and damping circuits
✔️ Educational electronics experiments
