1806Y1000123MXTE01

Overview

The Knowles Syfer 1806Y1000123MXTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 0.012 µF capacitance with a ±20% tolerance and a 100 VDC voltage rating. The component utilizes an X7R dielectric within a 1806 (4516 metric) package, measuring 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. It supports a continuous current of 300 mA and operates reliably between -55°C and +125°C.

Feature Summary

• Three-terminal feed-through architecture providing effective common-mode noise attenuation
• Nickel barrier termination structure ensuring robust solderability and environmental resistance
• High-current handling capability suitable for power line filtering applications

Applications

• EMI filtering on DC power input lines
• Noise suppression in automotive electronic control units
• Signal integrity protection in industrial communication interfaces

Procurement Notes

Verify the specific suffix 'E01' against the official datasheet to confirm the three-terminal filter configuration and nickel barrier termination details. Ensure the selected variant matches the required 300 mA current rating and 1806 footprint dimensions for your PCB layout constraints.

Selection Notes

Select this component when high-frequency noise rejection is required on low-voltage DC lines. The X7R dielectric offers stable performance across the operating temperature range. Consider the physical height of 1.3 mm for clearance requirements and verify that the 300 mA rating exceeds the maximum expected circuit current.
