Resistor 0.25W 43 ohm (10 pcs)

The Resistor 0.25W 43 ohm is a through-hole fixed resistor with a resistance of 43 Ω and a power rating of 0.25 W, sold in a pack of 10. This low E24 value is used as a MOSFET gate resistor, as a series resistor on fast signal lines and to build exact low resistances in series or parallel.

What's in the Box

• 10 × 43 Ω 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 43 Ω, the 0.25 W limit is reached at about 3.3 V across the resistor (about 76 mA), so it must never be connected directly across a 3.3 V or 5 V supply. Use it in series with a load and check the power with P = I² × R.
