SMD code U206

Marking codes are not standardised, and the same code is reused by unrelated makers for unrelated parts. Below is every part in our tables printed with it, and any printed with a code that is easy to misread as it, from the manufacturers' own marking tables and published code lists.

U206 on a chip capacitor

206 nF

206 nF capacitor

The u is both the decimal point and the unit: 206 nF.

Check it with a meter

Lift one end and measure it on a capacitance range. A good one reads close to 206 nF. In circuit the meter also sees everything connected across it, so the reading means little until it is out. A failed one usually reads near 0 Ω, or a steady low resistance, on the ohms range, often from a crack. On the board a shorted capacitor shorts its whole rail. A failed reading does not change what to fit: the marking still says 206 nF.

On a transistor or diode body (SOT-23, SMB, SOT-23-6), U206 is a part code instead. Those parts are listed below.

Is it dead?

Diode range and ohms range, part lifted.

Working, it reads

Depends on what it is. The datasheet, or an identical part, says.

Dead, it reads

  • Between two pins, the same reading both ways, near 0 V with a continuous beep: shorted.
  • Open between every pair of pins: failed open, or a part that reads open when working.
On the board
this is a first look only: the meter reads every path between those pins, and a short can be a neighbour. Lift one leg before you condemn it.
Compare:
If an identical part sits elsewhere on the board, measure it the same way: that is what this one should read.

A dead part still carries its marking. A short or an open says it has failed, not that it is a different part.

Was it this one?

Printed with a code easy to misread as U206

One character differs, and it is one that is easy to confuse under a lamp. Each code has a page of its own.

Codes that begin with U206

For a marking with its end worn or burnt off. Each code has a page of its own.
