GRM1555C1H101JA01D

GRM1555C1H101JA01D is a 100 pF ±5% C0G multilayer ceramic capacitor from Murata in a 0402 (1005 metric) case, rated 50 V DC — a precision value for RF matching, timing and filter positions where the capacitance must not wander. Murata's dimensions are 1.0 x 0.5 x 0.5 mm (±0.05 mm), the C0G dielectric is the EIA Class I characteristic with negligible temperature drift across the −55 °C to +125 °C operating range, and Murata's PIM database lists this exact code with production status available; both reflow and wave soldering are supported. The final D is the phi-180 mm paper-tape reel at 10,000 pieces. The selection point is C0G stability at ±5% in 0402. Selection advice: C0G is the deliberate choice over X7R here — where a circuit is tuned, a Class II part's voltage and temperature coefficients become part of the circuit whether you planned for them or not.
