MLCC GRM21A5C2E100FW01D

What is GRM21A5C2E100FW01D MLCC?

The GRM21A5C2E100FW01D is a multilayer ceramic capacitor manufactured by Murata. Key specs include 10pF capacitance, 250V voltage rating, C0G dielectric, 0805 package, and ±1% tolerance. RoHS compliant, it is designed for high-accuracy, high-voltage decoupling and timing applications.

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

Typical Applications & Why This Part Fits

• RF & Wireless Tuning Circuits: The tight ±1% tolerance and ultra-stable C0G dielectric ensure minimal drift in resonant tanks, critical for VCOs and filter networks.
• High-Voltage DC-DC Converters: Rated at 250V, this capacitor reliably snubs ripple spikes on secondary-side rectifiers without de-rating issues in a compact 0805 footprint.
• Precision Timing Delays: Low capacitance variation over temperature (C0G) makes it ideal for RC integrators or timing elements in industrial control modules.

Key Features & Advantages

• ±1% Capacitance Tolerance: Allows engineers to design with tighter margins, reducing calibration needs in measurement equipment.
• 250V High-Voltage Rating: Handles elevated power bus conditions while maintaining a low-profile 0805 case, saving board space.
• C0G (Class 1) Dielectric: Nearly zero voltage coefficient and low dissipation factor, guaranteeing predictable performance across voltage and temperature.

Frequently Asked Questions

1. Q: What makes GRM21A5C2E100FW01D different from a standard MLCC?
   A: Its combination of ±1% tolerance and 250V rating in 0805 package is uncommon; typical high-voltage parts offer only ±5% or ±10%. This delivers precision without sacrificing voltage headroom.
2. Q: Is GRM21A5C2E100FW01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply and flexible quantities for your engineering samples.
