1206J1000473MJTE03

Overview

The Knowles Syfer 1206J1000473MJTE03 is a feed-through ceramic capacitor designed for surface-mount applications. It features a capacitance of 0.047 µF with a voltage rating of 100 V and a current rating of 50 mA. The component utilizes X7R dielectric characteristics, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a compact 1206 (3216 metric) package, it integrates internal filtering capabilities directly into the circuit layout.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Provides high current handling capability rated at 50 mA
• Utilizes X7R dielectric material for consistent electrical stability under thermal stress

Applications

• High-frequency signal line noise suppression
• Power distribution network filtering
• EMI/RFI mitigation in compact electronic assemblies

Procurement Notes

Verify that the specific MJTE03 suffix corresponds to the required epoxy encapsulation and terminal configuration for your assembly process. Confirm that the 50 mA continuous current rating aligns with the operational load requirements of the target circuit to prevent component degradation or failure during sustained operation.

Selection Notes

Select this component when space constraints preclude discrete filter networks but feed-through attenuation is necessary. Ensure the 100 V DC rating exceeds the maximum peak voltage present in the application. Consider the physical dimensions of the 1206 package to verify compatibility with the printed circuit board land pattern and adjacent component spacing requirements.

Part Context

This part belongs to the Knowles Syfer 1206J series of high-reliability multilayer ceramic capacitors. The series is engineered for demanding environments where robust filtering and miniaturization are critical. The feed-through design distinguishes it from standard parallel-plate capacitors by providing a direct conductive path through the dielectric structure.
