1812Y0500823MJTE03

Overview

The Knowles Syfer 1812Y0500823MJTE03 is a feed-through ceramic capacitor with a capacitance of 0.082 µF and a rated voltage of 500V DC. It utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. The component features a 1812 (4532 Metric) surface-mount package with flexible terminals and a nickel barrier. It has a maximum current rating of 50 mA and meets AEC-Q200 automotive standards.

Feature Summary

• Integrated feed-through architecture for high-frequency noise suppression
• Flexible terminal design to withstand board flex stress
• Nickel barrier construction for enhanced reliability

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit designs
• High-voltage power supply filtering

Procurement Notes

Verify the complete part number including the MJTE03 suffix, as it denotes specific feed-through characteristics distinct from standard MLCCs. Confirm that the 50 mA current rating aligns with your application's peak load requirements. Ensure PCB layout accommodates the feed-through pin structure rather than standard two-terminal mounting.

Selection Notes

Select this component when both high-voltage handling and electromagnetic interference suppression are required in a single surface-mount device. The feed-through design offers superior performance compared to discrete capacitors and inductors. Verify that the 1812 footprint matches the target PCB land pattern for proper mechanical and electrical connection.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust ceramic capacitors for demanding environments. The 1812Y base indicates the 1812 case size and Y-series voltage coding. The MJTE03 suffix identifies it specifically as a feed-through variant with nickel barriers, differentiating it from standard parallel-plate MLCCs in the same family.

Replacement Considerations

Direct substitutes must match the feed-through topology and 500V rating. Standard MLCCs cannot replace this component due to the lack of integrated inductive filtering. Check for other Knowles Syfer feed-through parts with compatible current ratings and capacitance values if exact matches are unavailable.
