MLCC GRM21BB31C106KE15K

What is GRM21BB31C106KE15K MLCC?

The GRM21BB31C106KE15K is an SMD capacitor manufactured by Murata. Key specs include a capacitance of 10F, voltage rating of 16V, dielectric class B, and tolerance of ±10%, all housed in an 0805 package. RoHS compliant, it is designed for high-capacitance energy storage in compact circuits.

✔ RoHS Compliant  /  ✔ 0805 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• Power decoupling in IoT modules: The unusually high 10F capacitance at 16V provides substantial charge reservoir for burst loads, reducing voltage droop during radio transmission.
• Energy harvesting buffer circuits: With ±10% tolerance and B dielectric stability, this MLCC reliably stores intermittent harvest energy in low-power sensor nodes.
• Industrial actuator hold-up: The 0805 footprint withstands moderate vibration while delivering 10F supercap-like capacitance, enabling short-term backup for valve positioning.

Key Features & Advantages

• Ultra-high 10F capacitance: Replaces bulky supercapacitors in space-constrained designs, simplifying PCB layout.
• Rated 16V operation: Offers headroom above typical 3.3V/5V rails while maintaining low ESR for fast charge/discharge cycles.
• Murata process consistency: Tight ±10% tolerance ensures predictable performance across production batches, critical for charge balancing.
