1812Y5000153MSTE03

Overview

The Knowles Syfer 1812Y5000153MSTE03 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 0.015 µF with a DC voltage rating of 500V. The component operates within a temperature range of -55°C to +125°C and supports a current handling capacity of 50 mA. It utilizes a 1812 (4532 metric) package footprint, specifically engineered for three-pad configurations to ensure robust mechanical stability in high-vibration environments.

Feature Summary

• Integrated feed-through architecture providing superior electromagnetic interference suppression compared to standard capacitors
• Flexible terminal design enhances resistance to board flex-induced cracking during thermal cycling
• Three-pad mounting configuration ensures secure attachment on printed circuit boards

Applications

• Automotive electronics requiring AEC-Q200 compliance
• High-reliability industrial control systems
• Board-flex sensitive applications demanding enhanced mechanical durability

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the feed-through variant and three-pad pad layout. Standard MLCCs differ significantly from this feed-through topology. Confirm RoHS3 compliance and REACH status directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when electromagnetic interference filtering requires a through-hole performance level in a surface-mount form factor. The 500V rating suits high-voltage signal lines. Ensure the PCB layout accommodates the specific three-pad geometry required for proper grounding and signal passage.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability multilayer ceramic capacitors. The series is characterized by flexible terminations that mitigate stress on the ceramic body. This specific model integrates feed-through functionality, distinguishing it from conventional decoupling or bypass capacitors within the same product family.

Replacement Considerations

Direct substitutes must match the feed-through topology and 500V rating. Verify pinout compatibility for the three-pad arrangement. Generic MLCC replacements will not provide equivalent EMI suppression or mechanical integrity.
