NCAA1800BKNAHWS

Silicon Capacitors Overview

The NCAA1800BKNAHWS is a silicon-based RF capacitor manufactured by Vishay Electro-Films. It features a capacitance of 18 pF with a tolerance of ±10%. The component utilizes a nonstandard package size measuring 0.51 mm in length and width. Designed for high-frequency applications, it operates within a temperature range of -55°C to +125°C. The device employs surface mount technology (SMD/SMT) termination and is supplied in waffle pack packaging.

Silicon Capacitors Feature Summary

• Utilizes silicon thin-film technology for stable RF performance
• Compact nonstandard footprint suitable for dense layouts
• High-temperature stability up to 125°C

Silicon Capacitors Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal coupling

Silicon Capacitors Procurement Notes

Verify the specific nonstandard package dimensions against your PCB footprint library prior to ordering. Confirm that the ±10% tolerance aligns with your circuit design requirements. Ensure compatibility with standard reflow soldering profiles for thin-film components. Check lead time availability as manufacturing cycles may vary.

Silicon Capacitors Selection Notes

Select this component when small form factor and precise RF characteristics are required. The silicon construction offers advantages over ceramic alternatives in certain frequency ranges. Consider the 18 pF value and 10% tolerance for your specific network calculations. Evaluate thermal management needs given the 125°C maximum operating limit.

Silicon Capacitors Part Context

This part belongs to the NCAA series of silicon RF capacitors from Vishay Electro-Films. These components are designed for demanding radio frequency environments where stability and miniaturization are critical. The series provides alternatives to traditional ceramic capacitors in specific high-frequency applications.

Silicon Capacitors Replacement Considerations

NCAA1800BJNAHWS offers similar specifications but with tighter ±5% tolerance instead of ±10%. Engineers should verify if the looser tolerance of the BKNA variant is acceptable for their design margins before substituting.
