10pcs 100 ohms 4 band resistor 1/2w

🔹 10pcs 100 Ohms 4-Band Resistor – 1/2 Watt (0.5W), Carbon Film

This pack contains ten 100-ohm resistors with a 4-band color code and a power rating of 1/2 watt. These are ideal for circuits requiring higher power handling than standard 1/4W resistors, such as LED drivers, transistor biasing, current limiting, and general power supply applications.

✅ Specifications:

• Resistance: 100 Ohms (Ω)

• Power Rating: 1/2 Watt (0.5W)

• Number of Bands: 4-Band

• Type: Carbon Film or Metal Film (varies by batch)

• Tolerance: ±5% (Carbon) or ±1% (Metal) – verify

• Color Bands: Brown, Black, Brown, Gold (for ±5%)

• Maximum Working Voltage: 250V – 350V (depends on series)

• Temperature Coefficient: ±100ppm/°C to ±350ppm/°C (typical)

• Lead Type: Tinned copper, through-hole

• Quantity: 10 Pieces

📦 Applications:
✔️ High-brightness LED current limiting (higher power than 1/4W)
✔️ Power supply circuits
✔️ Transistor and MOSFET biasing
✔️ Voltage dividers in power stages
✔️ Snubber and damping circuits
✔️ Audio amplifier stages
✔️ Automotive electronics
✔️ DIY power projects

⚠️ Important Note:

• Power rating: 1/2W resistors are physically larger than 1/4W. Ensure PCB spacing fits.

• Voltage check: At 100Ω, 0.5W allows up to ~70mA (I²R calculation). Do not exceed.

• Color code: Brown (1) – Black (0) – Brown (x10) – Gold (±5%) = 100Ω ±5%.
