1206J0500104MJTE03

Overview

The Knowles Syfer 1206J0500104MJTE03 is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 0.1 µF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package measuring 3.2 mm x 1.6 mm, it offers a low-profile height of approximately 1.3 mm. This Class 1/Filter device integrates three terminals for efficient PCB layout and EMI filtering applications.

Feature Summary

• Integrates three-terminal feedthrough architecture for effective electromagnetic interference suppression within compact surface-mount footprints.
• Utilizes X7R ceramic dielectric to maintain consistent capacitance stability under varying thermal conditions and electrical loads.
• Provides direct pass-through signal integrity while shunting common-mode noise to ground through integrated internal structures.

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in automotive electronics
• EMI suppression in portable consumer devices

Procurement Notes

Verify the specific suffix 'MJTE03' against official Knowles Syfer documentation to confirm exact termination plating and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions. Cross-reference RoHS compliance status directly with the manufacturer's current environmental declarations prior to final procurement authorization.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering without additional discrete inductors. The 50V rating suits low-voltage logic and power rails. Confirm that the X7R temperature coefficient aligns with the operational environment requirements. Evaluate the 0.1 µF value against target frequency attenuation needs to ensure adequate impedance characteristics for the specific application bandwidth.
