Overview
The Knowles Syfer 1812J5000153MJTE03 is a feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 0.015 µF and a DC voltage rating of 500 VDC. The component operates within a temperature range of -55°C to +125°C and supports a maximum current of 50 mA. It utilizes a 1812 (4532 metric) package with a three-pad configuration.
Feature Summary
- Feed-through architecture providing integrated filtering capabilities
- Three-pad terminal design for enhanced mechanical stability
- High-voltage insulation suitable for sensitive circuit isolation
Applications
- High-voltage signal filtering in industrial electronics
- Power supply input/output noise suppression
- EMI/RFI mitigation in automotive systems
Procurement Notes
Verify the specific three-pad footprint requirements against your PCB layout, as this feed-through design differs from standard two-terminal MLCCs. Confirm that the 50 mA current rating aligns with your application's operational limits. Ensure compatibility with high-voltage assembly processes to maintain insulation integrity during soldering.
Selection Notes
Select this component when both high-voltage blocking and signal filtering are required in a single surface-mount device. The feed-through structure offers superior noise attenuation compared to standard capacitors. Consider the physical size constraints of the 1812 package and the need for three mounting pads during the schematic capture phase.
Part Context
This part belongs to the Knowles Syfer feed-through capacitor series, which integrates filtering functions directly into the component body. Unlike standard MLCCs, these devices utilize a central conductor pass-through to manage high voltages while attenuating electromagnetic interference across a broad frequency spectrum.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings before considering alternative manufacturers.
