1806J0500332MJTE07

Overview

The Knowles Syfer 1806J0500332MJTE07 is a high-reliability multilayer ceramic feed-through capacitor designed for surface-mount applications. It features a 3300 pF capacitance with a ±20% tolerance and a 50 VDC rated voltage. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 1806 (4516 metric) package, it integrates a built-in 2 A fuse function for circuit protection. This device combines EMI filtering capabilities with overcurrent protection in a single SMD/SMT form factor.

Feature Summary

• Integrates EMI filtering and overcurrent protection within a single surface-mount component
• Features a built-in 2 A fuse function for enhanced circuit safety
• Utilizes X7R dielectric for stable electrical characteristics across wide temperature ranges
• Designed for high-reliability applications requiring compact footprint solutions

Applications

• High-reliability electronic circuits requiring combined filtering and protection
• Space-constrained surface-mount designs needing integrated fuse functionality
• EMI suppression in sensitive signal or power lines
• Automotive and industrial systems demanding robust component integration

Procurement Notes

Verify the specific suffix TE07 against official Knowles Syfer documentation to confirm packaging details and compliance status. Ensure design compatibility with the 2 A fuse rating and 50 VDC limit. Cross-reference the 1806 package dimensions with PCB layout requirements. Confirm RoHS and REACH compliance through current manufacturer datasheets before finalizing procurement specifications.

Selection Notes

Select this component when both EMI filtering and overcurrent protection are required in a limited board area. The 3300 pF value suits specific frequency attenuation needs, while the 2 A fuse rating defines the maximum continuous current capacity. Consider the X7R temperature coefficient for environmental stability. Evaluate the 1806 footprint against available space constraints compared to discrete component combinations.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family, specifically engineered for demanding environments. The 1806J series denotes the case size and voltage class. As a feed-through capacitor, it differs from standard MLCCs by incorporating internal fuse technology. This integration reduces component count and simplifies assembly processes in critical electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify exact pinout and fuse characteristics if considering alternative manufacturers. Ensure any replacement matches the 1806 footprint, 50 VDC rating, and 2 A fuse specification.
