1812Y2000333MJTE03

Overview

The Knowles Syfer 1812Y2000333MJTE03 is a multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 33 nF nominal capacitance with a ±20% tolerance, rated for a DC voltage of 200 V. The component utilizes a Class 2 X7R dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in an 1812 (4532 Metric) surface-mount package, it offers low equivalent series resistance (ESR) and high ripple current capability, making it suitable for decoupling and filtering in demanding electronic circuits.

Feature Summary

• Utilizes X7R dielectric material for stable capacitance over varying temperatures
• Designed for high reliability in surface-mount configurations
• Capable of handling high ripple currents with low ESR

Applications

• High-voltage decoupling in industrial control systems
• Filtering applications in automotive electronics
