0402B332J500CT is a 0402 X7R capacitor from Walsin's General Purpose series: 3.3 nF ±5%, rated 50 VDC, decoded from the ordering table and confirmed in the X7R range grid.^{p.2, p.7} It is a BaTiO₃-based Class II ceramic — the approval sheet requires a 150 °C de-aging and 24 h rest before capacitance is even measured, a reminder that the label value is history- and drive-level-dependent.^{p.4, p.20}

The numbers you design against: capacitance within ±15% from −55 to +125 °C,^{p.4, p.14} dissipation factor ≤2.5% at 1 kHz / 1.0 Vrms,^p.12 insulation resistance 10 GΩ or R×C ≥ 500 Ω·F,^p.14 and a dielectric proofed at 250% of rated voltage.^p.13 Life testing runs 1,000 h at 125 °C and 200% of rated voltage with capacitance held within ±12.5%.^p.18 It ships 10,000 to a 7-inch paper-tape reel and is MSL 1.^{p.11, p.20}
