CC0402KRX5R8BB105

CC0402KRX5R8BB105 is a 1 µF ±10% X5R multilayer ceramic capacitor from Yageo in a 0402 (1005 metric) case, rated 25 V DC, documented by Yageo's per-part specification sheet: dimensions 1.0 x 0.5 x 0.5 mm (±0.05 mm), X5R across −55 °C to +85 °C, dissipation factor 10%, insulation resistance 50 MΩ, moisture sensitivity level 1, packed 10,000 per reel. The selection point is a full microfarad at a 25 V rating in 0402 — most 0402 1 µF lines stop at 6.3 V or 10 V, so this code serves 12 V-class decoupling without a case-size jump. Selection advice: the DF of 10% is the X5R trade in this size and belongs in the loss budget; and as with every high-density Class II part, size the position from the bias-derated value, not the nominal 1 µF.
