Resistor 0.25W 820 ohm (10 pcs)

The Resistor 0.25W 820 ohm is a through-hole fixed resistor with a resistance of 820 Ω and a power rating of 0.25 W (1/4 W), sold in a pack of 10. It is a common E12 value used for LED current limiting on 12 V supplies, transistor base resistors and voltage dividers. It is a practical part for Arduino projects, 12 V circuits and electronics classes.

Resistor 0.25W 820 ohm Specifications

• Resistance: 820 Ω (820 ohms)

Resistor 0.25W 820 ohm Applications

• LED current limiting on 12 V (about 12 mA with a red LED)
• Low-current LED indicators on 5 V (about 3.7 mA with a red LED)
• Base resistors for transistors driven from microcontroller pins
• Voltage dividers for analog inputs
• Electronics education and prototyping

What's in the Box

• 10 × 820 Ω 0.25 W resistors

Tip: With 820 Ω, the 0.25 W limit is reached at about 14 V across the resistor. With a red LED on 12 V it carries about 12 mA and dissipates about 0.12 W, within its rating.
