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

Typical Applications & Why This Part Fits

• High-frequency decoupling in RF modules: U2J dielectric offers extremely low capacitance drift and stable performance up to 1 MHz, ideal for maintaining signal integrity.
• Timer or oscillator circuits: The precise ±5% tolerance and minimal voltage coefficient ensure accurate timing constants in 50V-rated designs.
• Automotive sensor interface: Murata’s proven quality and the 0805 footprint suit harsh environments where reliable, compact decoupling is needed.

Key Features & Advantages

• U2J dielectric stability: Near-zero capacitance change over temperature (-55°C to +125°C) and voltage, outperforming X7R for precision applications.
• 0805 compact size: Balances layout density with easier hand-assembly and visual inspection, reducing manufacturing costs.
• 0.043 µF precise value: Non-standard capacitance enables custom filtering poles without adding parallel capacitors, simplifying BOM.

Frequently Asked Questions
