Murata GRM18 and GCM18 C0G MLCC (0603)

Murata Electronics · Multilayer ceramic capacitor, C0G · 0603 (1608 metric)

Murata 0603 C0G capacitors from two lines that share the 1608 body and land pattern: GRM18 (general purpose) and GCM18 (AEC-Q200 automotive grade). Both are 5% C0G parts used where the value must not move with temperature.

Part numbers: every value's LCSC, Mouser and DigiKey number is in the table below ("not listed" means that distributor has no listing for it). The symbol, the 3D model and the sidebar show one of them, GRM1885C1H272JA01D (2.7 nF), the value used most on the AM/FM board. murata-grm18-gcm18-c0g-0603-values.kicad_sym has a symbol for every value with its part numbers as properties.

Part numbers

Every row uses the same footprint, symbol and 3D model (same case size and land pattern). Values and ratings are from the LCSC parametric listing (2026-10-08); the linked datasheet is the source of truth.

Part number Capacitance Tolerance Voltage Rating Dielectric / TC LCSC Mouser DigiKey Datasheet
GRM1885C1H272JA01D 2.7nF ±5% 50V C0G C77034 81-GRM185C1H272JA01D 490-3283-2-ND PDF
