TheDEB1 EMI filter is a compact single-phase power line filter with a rated current of 1 A–6 A, suitable for 110/220 V AC (115/250 VAC) power supplies. It utilizes a dual-stage filter circuit design, providing excellent suppression of high-frequency common-mode and differential-mode interference from 100 kHz to 30 MHz.
The DEB1 features simple wiring and easy installation, making it ideal for home appliances, small industrial equipment, medical devices, LED/lighting systems, and other EMI-sensitive equipment. Custom configurations are supported, and sample testing is available upon request.

Key Features

  • Dual-stage filtering design – effectively suppresses power line conducted noise.
  • Rated current 1 A–6 A, suitable for low to medium power equipment.
  • Rated voltage 115/250 VAC, compatible with most national power grid standards.
  • Provides excellent suppression of both common-mode and differential-mode EMI interference in the 100 kHz–30 MHz frequency range.
  • Compact structure and easy installation – ideal for space-constrained or retrofit applications.
  • Excellent insulation and voltage withstand performance: line-to-line withstand voltage 1500 VDC, line-to-ground withstand voltage 2150 VAC; insulation resistance > 50 MΩ @ 500 VDC.
  • Customization (e.g., wiring method, current specifications) and sample testing are available, making it ideal for OEM/ODM customers.
  • UL certified, ensuring your product complies with local laws and regulations.

Selection Guide

When selecting a DEB1 EMI filter, please consider:
  1. Rated Current — Choose a 1 A–6 A model based on the maximum power consumption of your device.
  2. Filtering Requirements — For devices sensitive to 100 kHz–30 MHz EMI (such as electronics, LEDs, medical equipment, etc.), the dual-stage DEB1 provides strong suppression.
  3. Space/Installation Constraints — The compact structure of the DEB1 is suitable for devices with limited space or requiring modifications.
  4. Voltage Compatibility — Supports 115/250 VAC, suitable for global power grids.
  5. Customization Needs — Wiring methods, current ratings, certifications, etc., can be customized according to OEM/mass production requirements.

Installation Instructions

  • Connect the DEB1 in series with the AC power line (live wire + neutral wire) for optimal filtering performance.
  • Use wire-to-wire connections; if grounding is required (according to equipment requirements), ensure proper grounding.
  • Minimize wiring length to reduce parasitic inductance and improve filtering effectiveness.
  • Avoid routing sensitive signal lines parallel to power lines to reduce coupling interference.
  • For space-constrained or retrofit applications, the compact structure of the DEB1 facilitates installation.
