1806J1000270MCTE01

Overview

The Knowles Syfer 1806J1000270MCTE01 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-frequency applications. It features a C0G/NP0 dielectric material, ensuring stable capacitance across varying temperatures and voltages. The component operates within a DC voltage rating of 100 VDC and provides a nominal capacitance of 27 pF with a tolerance of ±20%. Housed in an EIA 1806 (4516 metric) package, it measures 4.5 mm in length, 1.6 mm in width, and 1.1 mm in height. The device supports a wide operating temperature range from -55°C to +125°C and utilizes SMD/SMT terminations for automated assembly.

Feature Summary

• Utilizes C0G/NP0 dielectric for minimal capacitance variation over temperature and voltage changes
• Designed for high-frequency signal coupling and decoupling in RF circuits
• Features robust nickel barrier termination structure for reliable soldering

Applications

• RF filter networks in communication equipment
• High-frequency oscillator tuning circuits
• Impedance matching networks in wireless transceivers

Procurement Notes

Verify the specific suffix 'MCTE01' against the manufacturer's current datasheet to confirm terminal plating and packaging configuration. Ensure the ordering part number matches the required capacitance tolerance and voltage rating for your circuit design. Cross-reference with official distributor catalogs to validate RoHS compliance status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a stable, low-loss capacitance is required in a compact 1806 footprint. The C0G dielectric makes it suitable for precision timing and RF applications where capacitance drift must be minimized. Consider the 100V DC rating and ±20% tolerance to ensure compatibility with your system's voltage headroom and frequency response requirements.

Part Context

This component belongs to the Knowles Syfer general-purpose MLCC line, specifically engineered for surface-mount technology. The 1806J series indicates a standard size code with J denoting the specific dimensional tolerance class. These capacitors are widely used in consumer electronics, industrial controls, and telecommunications infrastructure due to their reliability and consistent electrical performance.

Replacement Considerations

Direct substitutes include other 1806 package C0G capacitors with 27 pF ±20% rating from manufacturers like Murata or TDK. Verify that replacement parts maintain the same voltage rating, temperature coefficient, and termination style to ensure mechanical and electrical compatibility without redesigning the PCB layout.
