CL21B105KBFNNNE
SamsungCL21B105KBFNNNE is a 1.0 µF ±10% X7R multilayer ceramic capacitor from Samsung Electro-Mechanics in an 0805 (2012 metric) case, rated 50 V DC — the workhorse value for 24 V and 48 V-side decoupling and coupling. Samsung's dimensions are a tight 2.00 x 1.25 x 1.25 mm (±0.10 mm), the X7R dielectric holds ±15% across the full −55 °C to +125 °C range, and Samsung lists the base part in mass production with this E code in its package table. The selection point is X7R stability at 50 V in 0805: the part keeps its characteristic to +125 °C where an X5R line stops at +85 °C. Selection advice: for hot enclosures or automotive-adjacent environments the dielectric class, not the nominal value, is the decision — do not drop an X5R part into this position without re-checking the temperature budget.
