Applications
The B32923C3225M000 is primarily used as an X2 safety capacitor in AC line filters for switched-mode power supplies, motor drives, and home appliances operating on 230 V or 120 V mains. Its 2.2 µF capacitance at 305 V AC effectively attenuates conducted EMI in Class B filter stages, helping equipment meet CISPR 22 and EN 55032 emission limits. Industrial inverters and UPS systems also use this capacitor as a snubber element across power switching devices, where the 630 V DC rating provides adequate voltage margin.

Frequently Asked Questions
What voltage ratings does the B32923C3225M000 carry and which mains voltage systems does it support?
The B32923C3225M000 is rated at 305 V AC and 630 V DC. The 305 V AC rating covers both 120 V and 230 V mains systems with adequate derating margin, while the 630 V DC rating supports DC bus applications in motor drives and inverters. Its Safety Class X2 certification permits direct connection across AC mains lines without additional series protection.
How does the 2.2 µF capacitance of B32923C3225M000 contribute to EMI filter performance in a switched-mode power supply?
A 2.2 µF X2 capacitor across the AC input line forms a low-impedance shunt path for differential-mode conducted noise, typically providing 20 dB or more attenuation in the 150 kHz to 30 MHz frequency range when combined with a series common-mode choke. For a 50-ohm line impedance, 2.2 µF at 150 kHz presents about 0.48 ohms, diverting most differential interference current away from the mains and helping meet CISPR 22 Class B limits.
Why is polypropylene film chosen over ceramic or electrolytic types for the X2 safety capacitor application of B32923C3225M000?
Polypropylene film capacitors exhibit very low dissipation factor, typically below 0.001 at 1 kHz, which minimizes self-heating under continuous AC mains stress. Unlike ceramic X2 capacitors, polypropylene film does not suffer significant capacitance drop with applied voltage, maintaining the full 2.2 µF value at 305 V AC. Compared to electrolytic types, polypropylene film is non-polarized and withstands AC voltage continuously, essential for direct mains connection in X2 safety applications.
What physical dimensions and mounting considerations apply when designing the B32923C3225M000 into a PCB layout?
The B32923C3225M000 has a body height of 29.5 mm and uses through-hole mounting, requiring PCB holes spaced to match EPCOS B32923 series lead pitch. The tall 29.5 mm profile must be accommodated in the enclosure height budget, particularly in compact power supplies. Wave soldering is the standard assembly process, and the JESD-609 e3 rating confirms the component meets moisture sensitivity requirements for standard industrial assembly environments.
