1206J1000392MJTE03

Overview

The Knowles Syfer 1206J1000392MJTE03 is a feedthrough capacitor with a capacitance of 3900 pF and a DC voltage rating of 100 V. It features a ±5% tolerance and utilizes X7R dielectric characteristics. The component is housed in a 1206 (3216 metric) surface-mount package, measuring 3.2 mm in length, 1.6 mm in width, and 1.1 mm in height. It operates within a temperature range of -55°C to +125°C and includes an integrated 50 mA fuse for overcurrent protection.

Feature Summary

• Integrates a built-in 50 mA fuse for circuit protection against overcurrent events
• Provides electromagnetic interference filtering through X7R dielectric properties
• Utilizes a three-terminal surface-mount design for efficient PCB integration

Applications

• Electromagnetic interference suppression in sensitive electronic circuits
• Power line filtering for components requiring overcurrent protection
• High-reliability applications demanding compact filter solutions

Procurement Notes

Verify the specific suffix 'MJTE03' against official Knowles Syfer documentation to confirm the exact fuse rating and termination specifications. Ensure compatibility with standard 1206 footprints during layout. Confirm RoHS compliance status via the manufacturer's current datasheet before final procurement decisions.

Selection Notes

Select this component when both EMI filtering and inherent overcurrent protection are required in a single footprint. The 100V rating suits low-voltage DC lines. Consider the 50 mA fuse limit carefully to ensure it does not interrupt normal operational currents while still providing necessary fault protection for the connected load.

Part Context

This part belongs to the Knowles Syfer X2Y capacitor filter series, which combines decoupling and filtering capabilities. The 1206J prefix indicates a 1206 case size with a 100V rating. The MJTE03 suffix denotes specific terminal and packaging configurations unique to this product line variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout and electrical ratings if considering alternative brands or models from other manufacturers.

FAQ

What is the function of the internal fuse in this component?

The component integrates a 50 mA fuse that provides overcurrent protection by opening the circuit if the current exceeds this threshold.

What is the operating temperature range for this feedthrough capacitor?

The device is rated for operation between -55°C and +125°C.
