What is DK1B3EA221K86RBH01 MLCC?
The DK1B3EA221K86RBH01 is a SMD capacitor manufactured by Murata. Key specs include 220pF capacitance, 300V voltage rating, and ±10% tolerance. RoHS compliant, it is designed for high-voltage decoupling and noise filtering in space-constrained layouts.
✔ RoHS Compliant / ✔ SMD / ✔ Murata Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- DC-DC converter input/output filtering: The 300V rating handles high-voltage bus rails, while 220pF provides effective high-frequency noise suppression.
- Telecom line protection: Its compact non-standard SMD package fits tight PCB real estate, and the ±10% tolerance ensures consistent performance across temperature.
- Industrial sensor interfaces: The ceramic construction offers stable capacitance under bias, critical for precision analog circuits in harsh environments.
Key Features & Advantages
- High voltage capability: 300V rating exceeds many general-purpose MLCCs, enabling direct decoupling in 48V and 100V bus systems.
- Compact non-standard SMD package: Saves board space compared to leaded capacitors, ideal for miniaturized designs.
- Murata manufacturing excellence: Tight process control yields low ESR and reliable long-term capacitance stability.
Frequently Asked Questions
- Q: What makes DK1B3EA221K86RBH01 different from a standard 220pF MLCC?
