CC0603KRX7R0BB104

CC0603KRX7R0BB104 is a 0.1 µF ±10% X7R multilayer ceramic capacitor from Yageo in a 0603 (1608 metric) case, rated 100 V DC — and the rating is the whole story of this code. Yageo's per-part specification sheet gives dimensions 1.6 x 0.8 x 0.8 mm (±0.1 mm), X7R across −55 °C to +125 °C, dissipation factor 5%, insulation resistance 5 GΩ, moisture sensitivity level 1, packed 4,000 per reel. The selection point: the catalogue's other 0.1 µF 0603 Yageo, CC0603KRX7R9BB104, is a 50 V part — the 0 in this code's voltage field is the 100 V rating, and the two parts are not substitutes where the rail or the transient environment needs the headroom. Selection advice: match the full string; a one-character difference in the voltage field halves the rating, and the DF and IR figures differ between the two codes as well.
