1812Y0500153MSTE03

Overview

The Knowles Syfer 1812Y0500153MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 0.015 µF with a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material and offers a tolerance of ±20%. It operates within a temperature range of -55°C to +125°C. The package dimensions are 1812 (4532 metric), measuring 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height. It includes a nickel barrier and FlexiCap soft termination.

Feature Summary

• Integrated feed-through architecture providing inherent electromagnetic interference filtering capabilities within the component structure.
• FlexiCap soft termination design engineered to absorb mechanical stress and prevent solder joint cracking during board flexing.
• Nickel barrier construction utilized to enhance terminal integrity and improve resistance to corrosion and environmental degradation.

Applications

• Automotive electronics requiring AEC-Q200 qualification standards
• High-density circuit boards susceptible to mechanical flexure
• Signal lines requiring integrated EMI suppression

Procurement Notes

Verify the specific suffix MSTE03 against official Knowles Syfer documentation to confirm the feed-through configuration and nickel barrier specifications. Ensure compatibility with automated placement equipment regarding the 1812 footprint and terminal type. Confirm that the X7R dielectric characteristics align with the thermal requirements of the target application environment.

Selection Notes

Select this component when both high-frequency noise attenuation and mechanical durability are required in a compact form factor. The feed-through design eliminates the need for separate filter components, saving board space. Consider the X7R temperature stability if operating conditions exceed Class 1 dielectric performance needs while maintaining cost efficiency compared to C0G types.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability MLCCs featuring soft terminations. The series is widely adopted in automotive and industrial sectors where board flex reliability is critical. The specific model integrates filtering functions directly into the passive component, distinguishing it from standard parallel-plate capacitors.
