1812J2000103MXTE03

Overview

The Knowles Syfer 1812J2000103MXTE03 is a feedthrough capacitor with a capacitance of 10,000 pF and a DC voltage rating of 200 V. It operates within a temperature range of -55°C to +125°C. The component features a 1812 (4532 metric) surface-mount package with three terminals. It includes an integrated fuse rated at 50 mA for overcurrent protection.

Feature Summary

• Integrates a 50 mA fuse for circuit protection
• Provides EMI filtering in a compact SMD form factor

Applications

• High-frequency signal line filtering
• Power supply input protection
• EMI suppression in sensitive electronics

Procurement Notes

Verify the specific terminal configuration and fuse rating against the official datasheet before integration. Confirm that the 50 mA fuse threshold aligns with the target circuit's current requirements to prevent unintended interruption during normal operation.

Selection Notes

Select this component when combined EMI filtering and overcurrent protection are required in a single surface-mount device. Ensure the 1812 footprint fits the PCB layout constraints and that the 200 VDC rating exceeds the maximum operating voltage.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor series, designed for high-reliability applications. It combines ceramic dielectric properties with a built-in fusible link, offering a compact solution for noise reduction and safety in dense electronic assemblies.
