1812J1000823MJTE03

Overview

The Knowles Syfer 1812J1000823MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.082 µF and a rated voltage of 100V DC. The component operates within a temperature range of -55°C to +125°C and utilizes a C0G/NP0 dielectric material for stable performance. Housed in an 1812 (4532 metric) package, it integrates a built-in current rating of 50 mA. This device serves as an effective EMI filter solution for compact electronic designs requiring reliable signal integrity.

Feature Summary

• Integrated feed-through architecture combining filtering and conduction functions
• C0G/NP0 dielectric ensures minimal capacitance variation across temperature ranges
• Built-in 50 mA current handling capability for direct circuit integration
• Surface-mount design facilitates automated assembly in space-constrained applications

Applications

• EMI/RFI filtering in high-speed digital circuits
• Signal line protection in communication equipment
• Power supply input/output noise suppression
• Automotive electronics requiring robust electromagnetic interference mitigation

Procurement Notes

Verify the specific suffix codes against official Knowles Syfer documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with standard reflow soldering profiles for lead-free assemblies. Cross-reference the 1812 footprint dimensions with your PCB layout guidelines to guarantee proper pad design and thermal relief requirements are met during manufacturing.

Selection Notes

Select this component when a combined filtering and conduction path is required in a single surface-mount package. The 100V rating and 50 mA current limit define its operational boundaries. Consider the 0.082 µF value for low-pass filtering applications where high-frequency attenuation is critical. Verify that the C0G stability meets the precision requirements of the target signal path compared to higher-k dielectrics.
