The Samsung CL31B105KBHNNNE is a 1uF MLCC in 1206 package rated at 50VDC with X7R dielectric and ±10% tolerance. The 50V rating and robust 1206 package make it suitable for 12V, 24V, and 48V power rail decoupling in automotive and industrial systems. The X7R dielectric provides stable operation over the extended -55°C to +125°C temperature range.

The CL31B105KBHNNNE uses Samsung’s CL series MLCC technology with X7R dielectric to provide 1uF at 50V in the 1206 form factor. The X7R dielectric maintains capacitance within ±15% over the -55°C to +125°C range, making it suitable for under-hood automotive and harsh industrial environments. The 1206 package provides a larger pad area for reliable solder joints under thermal cycling conditions. The increased package size also provides higher ripple current capability compared to smaller footprints.
