1806J0500122MCTE01

Overview

The Knowles Syfer 1806J0500122MCTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 1200 pF with a tolerance of ±20%. The component operates at a DC voltage rating of 50V and supports a current rating of 300 mA. Housed in an 1806 (4516 metric) package, it utilizes a three-terminal architecture to provide effective electromagnetic interference filtering in compact circuit layouts.

Feature Summary

• Three-terminal feed-through architecture for enhanced EMI suppression
• High-current handling capability suitable for power line filtering
• Compact surface-mount footprint for dense PCB integration

Applications

• Electromagnetic interference filtering in electronic circuits
• Power supply input/output noise reduction
• Signal line protection in communication equipment

Procurement Notes

Verify the specific termination material and lead-free compliance status against the manufacturer's latest datasheet before integration. Confirm that the 300 mA current rating aligns with your application's peak load requirements. Ensure the 1806 package dimensions fit within your designated board space constraints. Cross-reference the capacitance value and tolerance with your circuit design specifications to guarantee proper filter performance.

Selection Notes

Select this component when a low-profile, high-current EMI filter is required for 50V DC applications. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the 1806 package size relative to available board real estate. Evaluate the 1200 pF capacitance value against the target noise frequency spectrum to ensure effective filtering without impacting signal integrity or power delivery.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in surface-mount EMI solutions. These components integrate capacitor functionality with a ground terminal to minimize parasitic inductance. The 1806 case size provides a balance between capacitance density and physical footprint, making them suitable for modern high-density electronics requiring robust noise suppression.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative feed-through capacitors by matching the 1806 package dimensions, 50V rating, 1200 pF capacitance, and 300 mA current handling capabilities.
