MLCC DK1B3EA681K86RAH01

What is DK1B3EA681K86RAH01 MLCC?

The DK1B3EA681K86RAH01 is a ceramic multilayer capacitor (MLCC) manufactured by Murata. Key specs include CAP CER 680PF 250V NONSTND SMD±10%. RoHS compliant, it is designed for high-voltage decoupling in space-constrained, non-standard SMD footprints.

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

Typical Applications & Why This Part Fits

• High-Voltage Snubber Circuits: The 250 V rating and 680 pF capacitance provide precise transient suppression in power inverters and motor drives, while the non-standard SMD case optimizes board space in custom layouts.
• DC-DC Converter Filtering: Its low capacitance (680 pF) offers high impedance at high frequencies, making it ideal for noise filtering on 200 V+ rails where standard sizes may not fit.
• Telecom Line Coupling: The ±10% tolerance ensures consistent AC coupling in telecom line interfaces, and the non-standard SMD package suits compact, non‑standard board designs.

Key Features & Advantages

• Non‑Standard SMD Package: Enables unique placement on boards where conventional case codes cannot be used, offering design flexibility without compromising electrical performance.
• High Voltage Rating (250 V): Supports robust operation in power electronics without derating concerns, extending system reliability.
• Murata Quality: Backed by strict production controls, ensuring stable capacitance (±10%) over temperature and lifetime.

Frequently Asked Questions

1. Q: What makes DK1B3EA681K86RAH01 different from a standard MLCC?
   A: Its defining feature is the non‑standard SMD footprint, which is designed for custom board geometries where common case sizes (e.g., 0402, 0603) cannot be used. The electrical specs remain a robust 680 pF at 250 V.
2. Q: Is DK1B3EA681K86RAH01 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 for this non‑standard MLCC.
