Samsung Electro-Mechanics CL21A476MQYNNNE

Product FAQ

• 1. What Are the Key Electrical Specifications for This Ceramic Capacitor?
  This Samsung Electro-Mechanics MLCC features a 47µF capacitance rating with a ±20% tolerance and a rated voltage of 6.3V. It utilizes an X5R dielectric, operating reliably across a temperature range of -55°C to +85°C. Supplied in a compact 0805 surface-mount package, it provides stable performance for space-constrained electronics.
• 2. Where Is This Ceramic Capacitor Commonly Used in Electronic Designs?
  This high-capacitance MLCC is ideal for low-voltage power supply decoupling, filtering, and smoothing in consumer electronics, IoT devices, and embedded systems. It excels in switching DC-DC converters, microcontroller power rails, and mobile hardware where low equivalent series resistance (ESR) and compact footprint are required for suppressing high-frequency voltage ripple and noise effectively.
• 3. What Design Guidelines Should Be Followed With DC Bias Effect?
  When deploying Class 2 X5R ceramic capacitors, engineers must account for capacitance derating under DC voltage bias. Operating close to the 6.3V rating reduces effective capacitance significantly. Ensure operating voltage stays well below maximum limits, allow sufficient circuit design margin, and verify ripple current ratings to ensure long-term stability and optimal decoupling in your circuit board design.
• 4. How Do I Ensure Package Compatibility on My Circuit Board Layout?
  This component uses an industry-standard 0805 (2012 metric) surface-mount footprint measuring approximately 2.0mm by 1.25mm. To guarantee seamless physical and electrical assembly, confirm your PCB layout land pattern matches 0805 SMT guidelines and verify that your automated pick-and-place equipment along with reflow soldering profiles accommodate standard 0805 ceramic chip capacitors properly.
• 5. How Can I Find Suitable Replacements or Alternatives for This Capacitor?
  When searching for equivalents to CL21A476MQYNNNE, select an 0805 ceramic capacitor with a 47µF rating, 6.3V or higher voltage tolerance, and an X5R or X7R dielectric. Ensure the substitute matches or exceeds dielectric temperature performance, physical package dimensions, and equivalent series resistance (ESR) specifications to maintain identical functional circuit behavior without PCB redesign.
