9 pF C0G/NP0 MLCC — 01005 precision class
The EMK042CG090DD-W is a 9 pF C0G/NP0 multilayer ceramic capacitor in the 01005 (0402 Metric) surface-mount package, rated 16 V — a precision-class part in a very small form factor that places real demands on stencil aperture control and pick-and-place feeder setup.
C0G/NP0 dielectric — zero-temperature-drift for timing and RF
C0G/NP0 is the most temperature-stable MLCC dielectric available; its capacitance drift is essentially zero across the full operating range, making it the right choice for resonator and filter circuits where the tuned value must not drift with temperature. The ±0.5 pF tolerance works with the C0G dielectric to hold that tuned value — this combination (tight tolerance plus zero TC) is why C0G/NP0 9 pF parts show up in VCO tank circuits, crystal oscillators, and RF impedance-matching networks where a few tenths of a picofarad matters.
Automotive temperature grade in 01005 — assembly sensitivity
The 01005 package — 0.40 mm by 0.20 mm with a 0.22 mm maximum thickness — demands a fine-pitch stencil and well-maintained pick-and-place nozzles; the part is mechanically fragile before reflow and the solder joint volume is critically small.
Sourcing — active production, Tape & Reel packaging
The M-series base product number implies a broad multi-size platform; confirm the BOM line matches the exact capacitance and voltage before committing, since the same base family covers many values in the same reel packaging. Tape-and-reel packaging is standard for this package size and is what the assembly house will expect for a high-volume reel-fed run; if the BOM is reel-count sensitive, specify the exact quantity-per-reel at quote time.
