The X7R/B series from EPCOS are multilayer chip capacitors offering high volumetric efficiency, low non‑linear capacitance change, high insulation resistance and strong pulse capability. They are suitable for blocking, coupling, decoupling and interference suppression applications.
The document lists detailed dimensions, rated voltage options, tolerance classes, termination types and ordering codes for each size, as well as characteristic curves for capacitance change, impedance, dissipation factor and insulation resistance versus temperature and voltage.
| Rated voltage | 16 V, 25 V, 50 V, 100 V, 200 V, 500 V |
|---|---|
| Capacitance tolerance | +5 % (J), +10 % (K), +20 % (M) |
| Termination types (soldering) | 0402‑1210: silver/nickel/tin; 1812‑2220: silver palladium |
| Termination types (conductive adhesion) | All sizes: silver palladium |
The X7R/B capacitors are offered with +5 % (J), +10 % (K) and +20 % (M) tolerance classes.
The series is available in 16 V, 25 V, 50 V, 100 V, 200 V and 500 V ratings.
For soldering, sizes 0402‑1210 use silver/nickel/tin terminations; for conductive adhesion all sizes use silver palladium.
