1812J0500563MJTE03

Overview

The Knowles Syfer 1812J0500563MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.056 µF with a ±20% tolerance and a rated DC voltage of 50 VDC. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it integrates a built-in 50 mA fuse element within the terminal structure to provide overcurrent protection alongside capacitive filtering.

Feature Summary

• Integrates a 50 mA fuse element directly into the terminal design for combined filtering and circuit protection
• Provides effective high-frequency noise attenuation through its feed-through architecture
• Maintains electrical stability using X7R ceramic dielectric material

Applications

• High-frequency noise suppression in sensitive electronic circuits
• Power line filtering where integrated overcurrent protection is required
• Signal integrity enhancement in compact surface-mount designs

Procurement Notes

Verify the specific current rating and fuse characteristics against the official datasheet before integration. Confirm that the 50 mA threshold aligns with the target circuit's operational limits. Ensure the 1812 footprint matches the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when simultaneous EMI filtering and fuse functionality are needed in a single SMD package. The 1812 size offers a balance between capacitance value and board space efficiency. Consider the X7R temperature coefficient for applications experiencing moderate thermal variations. Evaluate the 50 mA limit to ensure it does not interrupt normal circuit operation during peak loads.

Part Context

This part belongs to the Knowles Syfer series of specialized multilayer ceramic components. It differs from standard MLCCs by incorporating a conductive fuse path within the termination structure. This design allows for compact implementation of protection schemes without requiring discrete fuse components, streamlining the bill of materials for high-reliability applications.
