✔ RoHS Compliant  /  ✔ 0402 Package  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF Matching Networks: The 1.2pF ±0.05pF value and C0G/NP0 temperature stability make it ideal for impedance matching in 2.4 GHz ISM band circuits, minimizing insertion loss variation.
• High-Speed Clock Circuits: Low capacitance tolerance ensures precise load capacitance for crystal oscillators, reducing frequency deviation in data transmission modules.
• Sensor Compensation: 50V DC rating and low ESR support bias-sensitive sensor interfaces, maintaining signal integrity in automotive or industrial pressure sensors.

Key Features & Advantages

• Ultra-Tight Tolerance (±0.05pF): Enables consistent phase response in RF front-ends without post-tuning.
• C0G/NP0 Dielectric: Zero capacitance change with temperature and voltage, crucial for precision timing loops and VCO circuits.
• 0402 Case Size: Space-saving footprint allows dense PCB layout for miniaturized IoT devices and wearables.

Frequently Asked Questions
