1812J2000104MXTE07

Overview

The Knowles Syfer 1812J2000104MXTE07 is a feed-through multilayer ceramic capacitor (MLCC) designed for high-frequency noise suppression. It features a capacitance of 0.1 µF with a DC voltage rating of 200 V and a current rating of 2 A. The component utilizes an X7R dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in a standard 1812 (4532 metric) surface-mount package, it offers a compact footprint suitable for dense PCB layouts. The device provides effective electromagnetic interference (EMI) filtering while maintaining low impedance characteristics for signal integrity.

Feature Summary

• Integrated feed-through architecture combining decoupling and EMI filtering functions within a single surface-mount component.
• High current handling capability rated at 2 A, supporting power line applications without compromising filtering performance.
• X7R ceramic dielectric ensures consistent capacitance stability over the full industrial operating temperature range.

Applications

• Power supply input/output filtering for noise attenuation
• EMI suppression in high-speed digital circuits
• Signal line protection against electromagnetic interference

Procurement Notes

Verify the specific suffix 'E07' against official manufacturer documentation to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with standard 1812 footprints during PCB layout. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference pinout and terminal orientation requirements with the ECAD model provided by Knowles Syfer to prevent assembly errors.

Selection Notes

Select this component when space constraints require a combined decoupling and filtering solution in a 1812 package. The 200 V rating suits low-voltage DC bus applications. Consider the 2 A current limit for power rail integration. The X7R dielectric is appropriate for general-purpose filtering where moderate capacitance variation with voltage is acceptable. Evaluate thermal management needs given the self-heating potential under continuous 2 A load conditions.

Part Context

This part belongs to the Knowles Syfer XT series of feed-through capacitors, which integrate MLCC technology with coaxial-like structures for superior high-frequency performance. The 1812J prefix indicates the case size and voltage class within the broader Syfer portfolio. These components are engineered to replace traditional discrete filter networks, reducing board space and improving reliability in sensitive electronic systems.
