3825 Series X1/Y2 Safety-Certified MLCCs

The 3825 case size certified MLCC range builds on the established Knowles Syfer safety capacitor profile

Image of Knowles Syfer 3825 Series X1/Y2 Safety-Certified MLCCsKnowles Syfer 3825 series X1/Y2 safety-certified MLCCs were designed to address the rise in automotive electrification, renewable energy systems, and high-density industrial power supplies, which drive the demand for power electronics that deliver more performance in less space, all without compromising safety or long-term reliability. To support these demands, Knowles has expanded their X1/Y2 safety-certified surface-mount multilayer ceramic capacitor (MLCC) portfolio. The 3825 case size offers enhanced capacitance options, optimized creepage distance, and proven durability for high-voltage applications.

Features

  • Enhanced safety ratings: Industry-leading Class X1/Y2 certification with an extended capacitance range up to 18 nF at 310 VAC for robust interference suppression
  • Optimized high-voltage footprint: Minimum 7 mm creepage distance in a 3825 case size, enabling safe operation in high-voltage environments while maximizing PCB real estate
  • Superior environmental durability: Rated for 1500 VAC and certified to Humidity Grade IIIB (85°C/85% RH for 1,000 hours), ensuring long-term reliability in harsh, moisture-prone conditions
  • Automotive-grade reliability: AEC-Q200 qualified with flexible terminations to withstand mechanical flexure and thermal shock from -55°C to +125°C
Applications
  • Automotive and EV systems: High-power AC/DC converters, on-board chargers (OBC), and Y-capacitor filtering in DC/DC stages
  • Industrial infrastructure: Front-end AC filtering for datacenter servers, renewable energy inverters, and high-reliability industrial power supplies
  • Battery management systems (BMS)
  • DC/DC converters
  • AC/DC inverters
  • PTC heater controllers
  • E-compressor inverters
