1812Y1000183MJTE03

Overview

The Knowles Syfer 1812Y1000183MJTE03 is a surface-mount feed-through capacitor belonging to the FlexiCap series. It features an X7R dielectric with a capacitance of 18 nF and a voltage rating of 100 VDC. The component utilizes a 1812 (4532 metric) package with a maximum height of 0.75 mm. It supports a continuous current of 50 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated pass-through architecture enabling direct signal line routing through the component body
• X7R ceramic dielectric providing stable capacitance characteristics across the specified operating temperature range
• High continuous current handling capability suitable for power supply filtering applications

Applications

• Power supply input/output filtering in compact electronic modules
• Signal integrity management in high-density surface mount assemblies
• EMI suppression in portable devices requiring integrated pass-through components

Procurement Notes

Verify the specific suffix TE03 against official datasheets to confirm terminal configuration and packaging type. Ensure the 50 mA current rating aligns with circuit requirements. Confirm RoHS compliance status via manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when space constraints prevent separate filter placement. The 1812 footprint offers a balance between capacitance density and thermal performance. Verify that the 100V rating exceeds peak circuit voltages and that the 50mA limit accommodates load currents without derating issues.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in feed-through capacitors. These components integrate filtering functions directly into the circuit path, reducing board space compared to traditional discrete filter networks. The XT/Y series designations typically indicate specific terminal or packaging variations within the broader product line.

Replacement Considerations

Cross-reference with other 1812 feed-through capacitors from Knowles Syfer such as the 1812Y1000224METE03 for higher capacitance needs. Verify pin compatibility and current ratings when substituting with similar pass-through components from other manufacturers.
