Ohm Bands

SMD code 3R32 — 3.32 Ω

A surface-mount resistor has no bands. This one is a four-digit marking: the R is the decimal point — 3.32 Ω. Parts marked this way are usually ±1% or tighter.

Everything about 3.32 Ω — power ratings, what ten cost, what is in stock.

Same value, other markings

3.32 Ω is printed several ways depending on the part's precision and size. A board can carry all of them at once.

Codes you will mistake it for

One character apart from 3R32. On a 0402 part these are a fraction of a millimetre of printing — worth a second look before you solder.
