Automotive X5R MLCC in 1206
The EMK316BBJ226MLHT is a surface-mount multilayer ceramic capacitor from Taiyo Yuden's Series M, rated 22 µF at 16 V with an X5R temperature coefficient. AEC-Q200 qualification places it in the automotive screening bucket — this is the -40 to +85 °C ambient band that covers cabin and under-hood ECU module work, not the harshest under-hood zones, but clean enough for most body-control and comfort electronics modules. The 1206 footprint (3.20 mm × 1.60 mm) with a 1.80 mm max thickness is the standard decoupling size for automotive ECU layouts — it fits the typical 2–4 layer board without special pad geometry. X5R drift is ±15% across the operating range, so for a 16 V rail the 50% voltage derate against the part's rating gives comfortable headroom for transient spikes in an automotive power distribution network.
Reel options for BOM assembly
Base product number EMK316B ties directly into the Taiyo Yuden Series M family tree; any alternative in the same base series with matching capacitance, voltage, and package is a candidate cross-reference if you hit a lead-time wall on this specific date code.
