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

Typical Applications & Why This Part Fits

• High-Voltage Snubber Circuits: The 1 kV rating and low-loss U2J dielectric make it ideal for damping voltage spikes in power electronics.
• RF Filtering in Communication Modules: 100 pF with stable capacitance over temperature (U2J) ensures reliable performance in RF matching networks.
• DC-DC Converter Output Filtering: The 1206 case size allows efficient heat dissipation while the ±5% tolerance maintains tight regulation.

Key Features & Advantages

• High Voltage Rating (1 kV): Enables use in demanding power systems without derating concerns.
• U2J Dielectric: Excellent temperature stability and low ESR for high-frequency and resonance-critical circuits.
• Compact 1206 Footprint: Balances capacitance, voltage, and board space for modern compact designs.

Frequently Asked Questions
