1806J1000271MCTE01

Overview

The Knowles Syfer 1806J1000271MCTE01 is a three-terminal feed-through capacitor designed for surface mount applications. It features a capacitance of 270 pF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in the standard 1806 (4516 metric) package, it measures 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. This device is engineered for high-frequency noise suppression and EMI filtering in compact electronic circuits.

Feature Summary

• Three-terminal architecture provides enhanced high-frequency noise attenuation compared to standard two-terminal capacitors
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes
• Feed-through design integrates filtering directly into the signal path for efficient electromagnetic interference reduction

Applications

• High-speed digital circuit power distribution network filtering
• RF signal line noise suppression in communication equipment
• EMI filtering for sensitive analog components in mixed-signal systems

Procurement Notes

Verify the specific suffix MCTE01 against the manufacturer's current datasheet to confirm termination plating and reel specifications. Ensure the ordering quantity aligns with the manufacturer's standard packaging units. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when space-constrained designs require superior high-frequency filtering performance. The 1806 footprint offers a balance between capacitance value and physical size. Consider the three-terminal structure for applications where ground loop inductance must be minimized. Verify that the 100V rating exceeds the maximum circuit voltage including transients.

Part Context

This component belongs to the Knowles Syfer E01 series of multilayer ceramic feed-through capacitors. The series is characterized by its ability to provide effective EMI suppression in small surface-mount packages. The 1806 case size is widely used in consumer electronics and industrial control boards where space efficiency is critical.

Replacement Considerations

Direct substitutes may include other 1806 three-terminal feed-through capacitors from Knowles Syfer with identical electrical ratings. Verify pinout compatibility and physical dimensions before substitution. Alternative manufacturers may offer similar performance but require validation of mounting characteristics.
