Narrative:
I was working the sector at the beginning of an arrival sequence to the airport. Weather; high winds. Winds reported out of the south at 43 knots at 2000 feet by some jet arrivals. First few arrivals from the west uneventful. I noticed; of course; aircraft established on 10 mile final were losing 60-100 knots of ground speed. The first aircraft already cleared on final on tower frequency; aircraft X on a vector from the west approximately 10 miles away in-trail to join a 12 mile final.I issued a speed of 170 knots to aircraft X. Aircraft X joined final behind the lead aircraft with a little over 3 miles in trail; 100 knot overtake. The aircraft never descended. Realizing it was never going to work; I issued a turn to the east with a climb to 3000 feet; then another turn to heading 300. Strong winds pushing the aircraft to the north. The aircraft entered a 3900 foot minimum vectoring altitude area in the slide. I issued a climb to 4000 feet. It's been a few months since I worked an arrival sequence like that with strong winds. All day long there were reports of aircraft going around due to LLWS. Prebriefing yourself is very important; getting into a more conservative state of mind is essential. As an instructor; also; I've always taught 3 major things. Issue control instruction; verify correct readback; most importantly; and ensure the instruction is fulfilled.

Title: NCT TRACON Controller was vectoring an aircraft for re-sequencing at 3000 feet when the aircraft entered a 4000 foot minimum vectoring area.
