1806J0500123MJTE07

Overview

The Knowles Syfer 1806J0500123MJTE07 is a feed-through multilayer ceramic capacitor designed for surface mount applications. It features a capacitance of 0.012 µF with a ±20% tolerance and a rated DC voltage of 50V. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in an 1806 (4516 metric) package, it supports a continuous current rating of 2A. This device integrates filtering capabilities directly into the capacitor structure.

Feature Summary

• Integrates EMI filtering functionality within a standard surface-mount footprint
• Utilizes C0G (NP0) dielectric for high stability and low loss characteristics
• Supports continuous current ratings up to 2A for power line applications

Applications

• High-frequency noise suppression on power supply lines
• EMI filtering in compact electronic modules requiring integrated passives
• Signal conditioning in sensitive analog circuits

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination plating. Ensure the selected variant matches the required current rating and voltage derating for the target application environment. Cross-reference datasheet revisions to confirm compliance with current environmental regulations such as RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when board space constraints require combining decoupling and filtering functions. The 1806 package offers a balance between current handling capability and footprint size. Consider the C0G dielectric properties for applications demanding minimal capacitance variation over temperature and voltage changes compared to X7R alternatives.
