Designed for compact, non-standard SMD mounting, this MLCC is RoHS compliant and suited for circuits demanding stable capacitance under elevated DC bias.

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

Typical Applications & Why This Part Fits

• High-Voltage DC-DC Converters: The 300V rating makes it ideal for snubber and filter networks where voltage spikes must be suppressed without compromising reliability.
• Telecom & Infrastructure Power Supplies: Its 680 pF value provides precise high-frequency bypassing while the ±10% tolerance ensures consistent performance across production batches.
• Industrial Sensor Interfaces: The non-standard SMD footprint allows placement in space-constrained designs common in ruggedized sensor modules.

Key Features & Advantages

• 300V Withstand Voltage: Handles moderate power systems and transient events without derating concerns.
• Murata Proven Quality: Stringent manufacturing controls guarantee low leakage and stable capacitance over temperature.
• Compact Non-Standard Footprint: Enables layout flexibility where standard sizes cannot fit, simplifying PCB densification.

Frequently Asked Questions

1. Q: What makes DK1B3EA681K86RBH01 different from a standard SMD capacitor?
   A: Its non-standard footprint and 300V rating set it apart – most 680 pF MLCCs are rated at 50V or 100V. This part is engineered for higher voltage environments without a larger package.
2. Q: Is DK1B3EA681K86RBH01 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 with no minimum order penalties.
