1812Y1000154MJTE03

Overview

The Knowles Syfer 1812Y1000154MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 0.15 µF with a DC voltage rating of 100 VDC and a current rating of 50 mA. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it incorporates a three-pad footprint configuration to facilitate efficient PCB routing and thermal management.

Feature Summary

• Integrates feed-through architecture within a standard SMD form factor for compact circuit integration
• Utilizes C0G/NP0 dielectric for high stability and low loss characteristics
• Features a three-pad terminal design to enhance mechanical reliability and thermal dissipation

Applications

• High-frequency signal filtering in communication systems
• Power supply noise suppression in automotive electronics
• EMI/RFI mitigation in sensitive analog circuits

Procurement Notes

Verify the specific three-pad footprint requirements against your PCB layout, as this feed-through variant differs from standard two-terminal MLCCs. Confirm that the 50 mA current rating aligns with your application's operational limits. Ensure compatibility with the manufacturer's recommended reflow soldering profiles to maintain the integrity of the internal structure and terminal connections during assembly.

Selection Notes

Select this component when space constraints preclude through-hole feed-through capacitors but EMI suppression is critical. The C0G/NP0 dielectric makes it suitable for applications requiring minimal capacitance variation with temperature or voltage. Consider the 1812 package size relative to available board real estate and ensure the 100V rating provides adequate margin for the operating environment.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability ceramic capacitors. The 'J' suffix typically denotes the case size code, while 'M' indicates the capacitance value encoding. The 'T03' suffix identifies the specific terminal configuration and packaging style associated with the feed-through design, distinguishing it from general-purpose MLCCs in the same series.

Replacement Considerations

Direct replacements must match the 0.15 µF capacitance, 100 VDC rating, and specifically the three-pad feed-through terminal configuration. Standard two-terminal MLCCs are not electrically or mechanically equivalent substitutes due to the distinct grounding and signal path requirements of the feed-through design.
