CL21F105ZBFNNNE

CL21F105ZBFNNNE is a surface-mount multilayer ceramic capacitor (MLCC) in the CL21F family. The “105” code indicates a capacitance of 1,000,000 pF, i.e., 1 µF. It’s typically used for decoupling, filtering, and smoothing voltage rails on SMD boards. The remaining letters/numbers encode dielectric type, tolerance, voltage rating, and termination style, which vary by manufacturer. To know exact specs (dielectric class like X5R/X7R, tolerance, voltage rating, and package footprint), you should consult the specific datasheet or supplier page for this exact part.

CL21F105ZBFNNNE is a 1 µF MLCC capacitor (likely X7R) in the Murata CL21F family. Equivalents are other 1 µF X7R MLCCs with the same footprint and equal or higher voltage rating from vendors like Murata, TDK, Yageo, etc. To give exact cross parts, please confirm the package size (likely 0603/0612) and the voltage rating.

CL21F105ZBFNNNE is a surface-mount multilayer ceramic capacitor (MLCC) from the CL21F family.

What kind of company: A Japanese multinational electronics components company, specializing in ceramic capacitors and other passive components (filters, inductors, resonators, etc.).

CL21F105ZBFNNNE is a surface-mount MLCC capacitor (code 105 = ≈1 µF). Typical application areas include:
- Power-supply bypassing/decoupling for ICs, MCUs, and SoCs
- Smoothing and decoupling in DC-DC converters and voltage regulators
- Filtering and noise suppression on analog, RF, and high-speed digital lines
- EMI/RFI suppression on interfaces (USB, HDMI, Ethernet, etc.)
- General-purpose decoupling in consumer electronics, computing, networking, and industrial/automotive equipment (where ratings permit)

CL21F105ZBFNNNE is a ceramic MLCC capacitor. The exact SMD package size (e.g., 0805, 1206) is vendor-specific and not deducible from the part number alone—check the manufacturer’s datasheet for the precise package.
