Secondary dominant is one of the very common chromatic chords. It is a chromatic chord because the chord is not constructed out of piling thirds on each scale degree of the home key. In other words, in order to construct this chord (and any other chromatic chords) you will need to use chromatic notes, notes that are out of the key.
Secondary dominant is simply a dominant chord to a degree of the scale. It could be in three different forms: either as a regular triad, a dominant 7th chord, or a diminished 7th chord.
For example, in C major, a secondary dominant chord to the second degree (since the chord formed on the 2nd degree is a D minor chord, you consider the "new tonic" in the key of D minor), could be A-C#-E (V/ii), A-C#-E-G (V7/ii) or C#-E-G-B flat (vii7/ii).
You should label secondary dominant according their inversion as well.
