1806J0500152MCTE01

Overview

The Knowles Syfer 1806J0500152MCTE01 is a three-terminal feed-through capacitor designed for surface mount technology. It features a capacitance of 1500 pF with a ±20% tolerance, rated for a DC voltage of 50 VDC. The component operates within a temperature range of -55°C to +125°C and utilizes C0G dielectric material. Its physical dimensions conform to the 1806 (4516 metric) package size, measuring 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. The device supports a current rating of 300 mA and includes a nickel barrier termination.

Feature Summary

• Three-terminal EMI filter architecture providing superior high-frequency noise suppression compared to standard two-terminal capacitors.
• Feed-through design enables low-inductance grounding, enhancing signal integrity in sensitive RF applications.
• C0G/NP0 dielectric ensures stable capacitance performance across varying temperatures and voltages.

Applications

• RF circuit filtering in communication systems
• Power supply decoupling for noise reduction
• EMI suppression in high-speed digital interfaces

Procurement Notes

Verify the specific suffix MCTE01 against the manufacturer's latest datasheet to confirm packaging details and terminal plating specifications. Ensure compatibility with PCB footprint requirements for the 1806 package. Cross-reference RoHS compliance status with current regulatory standards before integration into production designs.

Selection Notes

Select this component when low parasitic inductance is critical for EMI performance. The three-terminal structure offers better attenuation than standard MLCCs at high frequencies. Consider the 300 mA current rating and 50 VDC limit during circuit design to ensure reliable operation under expected load conditions.

Part Context

This part belongs to the Knowles Syfer E01 series of high-reliability ceramic capacitors. The series is engineered for demanding environments requiring stable electrical characteristics. The 1806J prefix indicates a specific voltage and capacitance coding within the broader product line, distinguishing it from other series like H or K variants.

Replacement Considerations

Direct substitutes must match the 1806 package, 1500 pF capacitance, 50 VDC rating, and three-terminal feed-through configuration. Verify that alternative components maintain equivalent C0G dielectric properties and current handling capabilities to preserve circuit performance.
