1812J5000273MXTE03

Overview

The Knowles Syfer 1812J5000273MXTE03 is a feed-through, pass-through multilayer ceramic capacitor designed for surface mount applications. It features a capacitance of 0.027 µF with a DC voltage rating of 500 VDC and an X7R dielectric material. The component operates within a temperature range of -55°C to +125°C and exhibits a tolerance of ±20%. Housed in an 1812 (4532 metric) package, it includes a 50 mA current rating and utilizes three printed circuit board pads for mounting.

Feature Summary

• Feed-through architecture providing integrated filtering capabilities
• High-voltage handling capability suitable for demanding circuits
• Surface mount design for automated assembly integration

Applications

• High-frequency signal filtering
• Power supply decoupling
• EMI suppression in sensitive electronics

Procurement Notes

Verify the specific terminal configuration and pad layout requirements against your PCB design before ordering. Confirm that the 50 mA current rating meets your application's operational limits. Ensure compatibility with the specified 1812 footprint dimensions to prevent mechanical interference during assembly.

Selection Notes

Select this component when a combined filtering and decoupling function is required in a compact form factor. The X7R dielectric offers stable performance across the operating temperature range. Consider the three-pad mounting structure for secure attachment and optimal electrical connection in high-reliability designs.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which integrates passive components into a single surface-mount device. These capacitors are engineered to reduce parasitic inductance compared to traditional discrete components. The 1812J series specifically targets applications requiring robust performance in space-constrained environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative manufacturers or different series from the same brand.
