1206J1000123MJTE03

Overview

The Knowles Syfer 1206J1000123MJTE03 is a feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 0.012 µF with a tolerance of ±20%. The component operates at a DC voltage rating of 100 V and supports a continuous current of 50 mA. Utilizing C0G (NP0) dielectric, it ensures stable performance across a temperature range of -55°C to +125°C. The physical dimensions conform to the standard 1206 (3216 metric) package size.

Feature Summary

• Integrated feed-through architecture combining filtering and decoupling functions within a single SMD component
• High-current handling capability supporting up to 50 mA continuous operation
• C0G/NP0 dielectric material providing minimal capacitance variation over temperature and voltage changes

Applications

• RF signal path filtering in communication modules
• Power distribution network decoupling in high-frequency circuits
• EMI suppression in sensitive analog signal lines

Procurement Notes

Verify the specific suffix 'MJTE03' against official Knowles Syfer documentation to confirm packaging configuration and terminal plating specifications. Ensure the selected variant matches the required 50 mA current rating and 1206 footprint constraints for your PCB layout. Cross-reference the datasheet for any recent manufacturing updates or environmental compliance statements.

Selection Notes

Select this component when space-constrained designs require simultaneous power delivery and noise filtering. The feed-through structure reduces parasitic inductance compared to discrete components. Confirm that the 100V rating exceeds the maximum circuit voltage and that the 50mA limit accommodates peak load currents without thermal degradation.

Part Context

This part belongs to the Knowles Syfer J-series of high-reliability MLCCs. The J-series typically targets automotive and industrial applications requiring robust performance. As a feed-through type, it differs from standard parallel-plate capacitors by allowing current to pass through the center conductor while shunting noise to ground.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feed-through capacitors based on identical 1206 dimensions, 100V rating, and 50mA current capacity.
