Overview
The Knowles Syfer 1812Y0500103MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) featuring a 10 nF capacitance and a 50 VDC voltage rating. It utilizes X7R dielectric material with a ±20% tolerance. The component is housed in an 1812 (4532 metric) package, measuring 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height. It employs a nickel barrier with 100% tin termination system and operates within a temperature range of -55°C to +125°C.
Feature Summary
- X2Y architecture providing integrated common-mode noise filtering capabilities
- FlexiCap technology utilizing flexible terminations to enhance board flex sensitivity
- Nickel barrier end-termination structure ensuring reliable solderability
Applications
- Automotive electronics requiring AEC-Q200 qualification
- Circuits sensitive to mechanical board flexing
- High-frequency noise suppression in power lines
Procurement Notes
Verify the specific suffix 'MJTE03' against official datasheets to confirm X2Y configuration and FlexiCap termination details. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Confirm RoHS compliance status for the target market regulations before finalizing procurement orders.
Selection Notes
Select this component when simultaneous decoupling and EMI filtering are required in space-constrained designs. The X2Y topology reduces component count compared to discrete solutions. Verify that the 50V rating provides sufficient margin for the application's peak voltage transients and operating conditions.
Part Context
This part belongs to the Knowles Syfer Y5P series, which integrates three terminals into a single MLCC body. The series combines standard capacitance functions with electromagnetic interference suppression. It targets applications demanding high reliability and reduced footprint in complex electronic assemblies.
Replacement Considerations
Direct substitutes include other X2Y capacitors from Knowles Syfer with identical capacitance and voltage ratings. Verify terminal flexibility and package dimensions match the existing PCB layout constraints before substitution.
