Applications
The VY2472M49Y5US63V7 is designed for AC mains EMI suppression filters in switching power supplies, motor drives, and household appliances where Y2 and X1 rated capacitors are required between line-to-ground and line-to-line for effective interference attenuation. Its 4.7 nF capacitance provides high-frequency bypass above 1 MHz, suppressing conducted emissions in the 150 kHz to 30 MHz CISPR 22/EN 55022 compliance range. The through-hole package with 12.5 mm body height is suited for single-phase AC filter networks positioned near the mains inlet of power supply modules and EMC-compliant industrial equipment.

Frequently Asked Questions
What safety class ratings does the VY2472M49Y5US63V7 carry, and how do Y2 and X1 certifications differ in AC line filter designs?
The VY2472M49Y5US63V7 is dual-rated Y2 and X1 safety classes. Y2 capacitors are connected from line or neutral to protective earth ground in single-phase AC systems rated up to 250 V AC, providing a safe failure mode if the capacitor opens rather than shorts. X1 capacitors are connected across the line (line-to-neutral) and are rated for impulse voltages up to 4 kV peak, making this part suitable for both across-the-line and line-to-ground positions in a complete EMI filter stage at 230 V mains.
At what frequencies does the 4.7 nF capacitance of the VY2472M49Y5US63V7 provide effective mains interference attenuation?
At 4.7 nF, the VY2472M49Y5US63V7 provides effective impedance below 34 Ω at 1 MHz, dropping to 3.4 Ω at 10 MHz, making it highly effective for suppressing conducted EMI in the 1 MHz to 30 MHz range required by CISPR 22 Class B. When combined with a common-mode choke of 1 mH to 10 mH, the 4.7 nF Y-capacitor forms a low-pass filter with a -3 dB cutoff frequency below 500 kHz, attenuating switching noise from 100 kHz DC-DC converters by more than 40 dB.
How does the through-hole package height of 12.5 mm affect placement in a power supply EMI filter stage?
The 12.5 mm body height of the VY2472M49Y5US63V7 requires PCB-to-chassis clearance of at least 15 mm above the PCB surface, which is typical in standard power supply PCB assemblies with 20 mm or more of internal chassis height. Through-hole mounting provides robust mechanical anchoring compared to SMD safety capacitors, which is important at the AC inlet position where connectors and cables may exert mechanical stress on solder joints during repeated plug-and-unplug operations.
Can the VY2472M49Y5US63V7 replace a film Y-capacitor in an existing EMI filter, and what trade-offs does this involve?
In terms of safety ratings, the VY2472M49Y5US63V7 can replace a film Y2/X1 capacitor of equivalent 4.7 nF capacitance in an existing filter design since both share identical Y2/X1 certification and 250 V AC mains ratings. The ceramic construction offers smaller physical size and potentially longer lifetime at high temperatures above 85°C compared to metallized polypropylene film alternatives. However, ceramic Y-capacitors can exhibit a piezoelectric acoustic noise effect at audio frequencies (100 Hz to 20 kHz), which should be evaluated in low-noise power supply designs near audio equipment.
