The X7R/B multilayer chip capacitors from Siemens Matsushita Components are designed for high‑volumetric efficiency applications such as blocking, coupling, decoupling, and interference suppression. They are offered with various termination options, including silver/nickel/tin and silver palladium, and are packaged in blister, cardboard tape, or bulk cases.
Key specifications include rated voltages from 16 V to 500 V, capacitance tolerances of ±5 % (J), ±10 % (K) and ±20 % (M), and dimensions for standard sizes (e.g., 0402: 1.0 mm × 0.5 mm). Ordering codes and detailed insulation resistance and capacitance‑change curves are provided for each voltage and size variant.
