What are the key features of R474I22205001K?
- X2 safety rating for across-the-line (line-to-line) EMI suppression in AC mains applications
- 0.022 µF capacitance at 440 VAC continuous working voltage with 10% tolerance
- Radial through-hole lead configuration for easy PCB mounting and wave soldering
- Meets IEC 60384-14 X2 class requirements for use directly across AC power lines
- Film dielectric construction providing self-healing properties for improved long-term reliability
What is R474I22205001K used for?
R474I22205001K is used in across-the-line EMI filtering stages in switching power supplies, motor drives, and home appliances operating from 230 VAC or 120 VAC mains where X2-rated suppression capacitors are required by safety standards. Its self-healing film dielectric ensures continued safe operation even after partial dielectric breakdown, a mandatory characteristic for components placed directly across AC line voltage.

Frequently Asked Questions
What does the X2 safety rating mean for R474I22205001K, and which AC mains voltages can it support?
The X2 rating certifies that R474I22205001K is approved for direct connection across the AC supply line (line-to-line) in equipment operating from standard mains voltages. With a 440 VAC working voltage and 0.022 µF capacitance, it is suitable for 120 VAC and 230 VAC applications and complies with IEC 60384-14, which mandates self-healing film construction for this safety class.
How does the 0.022 µF capacitance of R474I22205001K affect its EMI attenuation performance in a mains filter?
At 0.022 µF (22 nF), this X2 capacitor provides differential-mode EMI attenuation across the AC mains lines. Combined with a line inductance of a few µH, it forms a low-pass filter that begins attenuating conducted interference above roughly 100 kHz to several MHz, making it effective for suppressing switching noise from power supplies and motor controllers operating at typical switching frequencies.
What is the lifecycle and procurement outlook for KEMET R474I22205001K, and are there direct alternate part numbers?
KEMET R474I22205001K is an active product in KEMET's R474 series of X2 film safety capacitors. The 0.022 µF, 440 VAC, 10% radial variant is a standard commercial value, so it is stocked by major distributors. Functionally equivalent alternates exist from other manufacturers such as WIMA, Vishay, and TDK in the same 0.022 µF X2 rating at 275 VAC to 440 VAC.
