Advance Transformer Co. 7C225P30-R is a 22.5 µF dry‑film capacitor rated for 300 VAC and 50/60 Hz, designed for HID lamp ballast applications in Philips Advance ballast systems. Its enclosure is approximately 1.75 inches in diameter and 3.75 inches tall, a compact form typical of this model within the 7C225 family. This family includes other voltage variants, such as 7C225P34 rated for 345 VAC and 7C225P40 rated for 400 VAC, all sharing the same 22.5 µF capacitance to support ballast networks across different supply voltages.
