Questions about this product
- What values come in this capacitor kit?
- You get five film capacitors, one each of 0.1uF, 0.15uF, 0.22uF, 0.33uF, and 0.47uF. All are rated 250V to 275V AC with flexible wire leads for easy soldering. That spread covers a wide range of mains filtering needs.
- What are these X2 capacitors used for?
- They go across AC mains lines to suppress EMI and RFI noise and smooth out transient voltage spikes. A common spot is the AC input of a switch-mode power supply. They help cut line noise and protect downstream parts.
- Are these safe to wire directly across AC mains?
- Yes, X2 class capacitors are designed for across-the-line use, meaning line to line on the mains. They are built to fail safely rather than short out, which protects the circuit and user. The kit is rated 250V to 275V AC for that duty.
