A
1, 3, 5 · A, C#, E
The third is the note that makes a chord sound major or minor. Take it out and the chord sits in between. That is a suspended chord, or sus chord.
On C, the major chord is C, E, G. The minor chord is C, Eb, G. Csus2 is C, D, G: D stands where E was. Csus4 is C, F, G: F stands where E was.
When a chart just says sus, it means sus4. If the writer wants the 2nd, they write sus2.
An A suspended chord on guitar is Asus2 or Asus4. A major is A, C#, E. A minor is A, C, E. Asus2 puts B in the third's place: A, B, E. Asus4 puts D there: A, D, E. These shapes are standard tuning with no capo. Change the root for the other eleven. One named chord, including a sus chord, can also be opened in the chord finder.

The two chords are also compared side by side, with the note names for all twelve roots, one shape on each root string and two intervals measured in a public-domain recording, on sus2 chord and sus4 chord.
Plenty of visitors arrive with a single chord in mind rather than a family of twelve. Each page below stays on one root: the shapes with their fret numbers, the note every string sounds, the degree of each of those notes, and a switch between the sus2, the sus4 and the plain major triad on that root.
Sus on its own means sus4. Sus2 is the one that uses the 2nd. They are not the same chord: on C, sus4 is C, F, G and sus2 is C, D, G.
They are the same suspended chords, played as shapes. You already know a major or minor grip. Move the finger that plays the third to the 2nd or the 4th, and you have the sus chord. The shapes above are suggestions, not the only fingering.
People who type "a suspended chord guitar" are usually asking for the A chord. Use the A root above: Asus2 reads X 0 2 2 0 0 and Asus4 reads X 0 0 2 3 0. Both are open chords.
The table on this page lists sus2 and sus4 for C through B. It is not a PDF. Sharp roots are included; a chart of only C, D, E, F, G, A and B leaves five roots out.
The third is held back. The 2nd or the 4th is hanging where the third would be, and the ear often wants the major or minor chord to follow. You do not have to resolve it. Plenty of songs stay on the sus chord.
A 7sus chord keeps the 4th and adds a flat 7th. That is a different chord from the three-note sus2 and sus4 on this page. A minor seventh still has a third. Compare those four-note chords on minor seventh chord guitar.
The five seventh types on one root are on 7th chords guitar.
