1206J1000183MJTE07

Overview

The Knowles Syfer 1206J1000183MJTE07 is a surface-mount feed-through capacitor in a 1206 (3216 metric) package. It features a capacitance of 0.018 µF with a voltage rating of 100 V and a tolerance of ±20%. Designed for high-frequency noise suppression, it supports a continuous current of 2 A. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated feed-through architecture providing simultaneous signal conduction and electromagnetic interference filtering
• High-current handling capability suitable for power line applications
• Compact surface-mount footprint designed for space-constrained circuit board layouts

Applications

• High-frequency noise suppression on data lines
• Power line filtering in compact electronic modules
• Electromagnetic interference mitigation in signal transmission paths

Procurement Notes

Verify the specific suffix 'JT' confirms the feed-through construction, as standard MLCCs lack this topology. Confirm the 2 A current rating aligns with thermal management requirements. Ensure the 1206 pad layout accommodates the three-pad configuration required for the internal conductor. Validate that the X7R characteristics meet the operational stability needs for the target environment.

Selection Notes

Select this component when integrated filtering and signal continuity are required in a single device. The feed-through design eliminates the need for separate shunt capacitors and series inductors. Consider the 1206 size constraint against available board real estate. Evaluate the 100 V rating against peak transient voltages to ensure adequate margin for long-term reliability.

Part Context

This part belongs to the Knowles Syfer J-series, which specializes in feed-through capacitors. Unlike standard multilayer ceramic capacitors, these components integrate a central conductor to pass signals or power while shunting noise to ground. This topology offers superior high-frequency performance compared to discrete filter combinations.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 0.018 µF capacitance, 100 V rating, and specifically the feed-through construction. Standard MLCCs cannot replace this function without redesigning the circuit for separate filtering components.
