What the 4-capacitor isolated array delivers on a BOM line
The CL31B104KACNBNC packs four isolated 0.1 µF ceramic capacitors into a single 1206 (3.20 mm × 1.60 mm) SMD body, cutting component count and placement operations compared to four individual 1206 caps.
With ±10% tolerance at 25 °C and the X7R tempco governing the drift band, this part is sized for bypass and decoupling duty — not for precision RC time-constant paths. If the board is running signal-chain filtering close to the Nyquist boundary, the accumulated drift across the temp range can push the corner frequency outside the intended band. For that role a COG/NPO part with tighter tempco would be the spec to seek, but at the cost of lower volumetric density and higher per-capacitor board area.
Package profile and board integration
The seated height is capped at 1.00 mm — the ultra-low profile is set by the 3.20 mm × 1.60 mm body and the ceramic stack-up within the package.
