Overview
The Knowles Syfer 1206J2000390MCTE03 is a surface-mount feed-through capacitor with a capacitance of 39 pF and a voltage rating of 200 VDC. It utilizes C0G/NP0 dielectric material for stable performance across temperatures ranging from -55°C to +125°C. The component features a 1206 (3216 metric) package size with standard SMD/SMT termination. It includes an integrated 50 mA current rating, distinguishing it as a pass-through device designed for high-frequency noise suppression in compact electronic assemblies.
Feature Summary
- Integrated feed-through architecture enabling simultaneous signal transmission and high-frequency noise filtering within a single surface-mount footprint.
Applications
- High-frequency noise suppression in RF signal lines
- EMI filtering for sensitive communication interfaces
- Compact circuit board designs requiring integrated pass-through filtering
Procurement Notes
Verify the specific E03 suffix designation against official Knowles Syfer documentation to confirm the integrated 50 mA current rating and feed-through topology. Ensure compatibility with 200 VDC operating conditions and C0G/NP0 temperature stability requirements for the target application environment.
Selection Notes
Select this component when space constraints preclude discrete filter components while maintaining signal integrity. The 1206 form factor offers a balance between current handling capability and board real estate efficiency compared to smaller packages.
Part Context
This part belongs to the Knowles Syfer 1206J series of multilayer ceramic capacitors. It represents a specialized subset of MLCCs engineered specifically for feed-through applications, combining the electrical characteristics of Class 1 capacitors with structural features for inline mounting.
FAQ
What is the maximum continuous current rating for this component?
The component has an integrated current rating of 50 mA.
Does this capacitor support bidirectional signal flow?
Yes, as a feed-through capacitor, it is designed to allow signal passage through its internal structure while shunting high-frequency noise to ground.
