The CAP CER 180PF 50V X7R 1808 is a specific type of ceramic capacitor. It has a capacitance value of 180 picofarads, operates at 50 volts, and falls under the X7R category, which is a common classification for certain types of ceramic capacitors due to their temperature stability characteristics. This particular component is available in the metric size 1808 (which also corresponds to the designation 4520). The ±5 notation indicates that the value of capacitance may vary within this range, reflecting some tolerance or manufacturing margin.
