Eaton 1383B-6501 Single‑Phase EMI Filter

The Eaton 1383B-6501 is a robust electromagnetic interference (EMI) filter designed to mitigate conducted noise on AC power lines. Part of the well‑known 1383B series, this filter is engineered for applications where reliable attenuation of both common‑mode and differential‑mode noise is critical. Its compact chassis‑mount metal case ensures easy installation inside electrical enclosures while providing excellent shielding.

Key Features

• Single‑phase operation (250 VAC, 50/60 Hz)

• High insertion loss across a wide frequency range (150 kHz – 30 MHz)

• Low leakage current version suitable for medical equipment

• Compact metal housing with flange mounting

• Fast‑on terminals or wire leads (depending on variant)

• Complies with UL, CSA, and ENEC safety standards

Technical Specifications

Electrical Performance

The 1383B-6501 employs a balanced LC network with X‑capacitors, Y‑capacitors, and high‑permeability inductors to achieve superior noise attenuation. Typical insertion loss at 1 MHz exceeds 40 dB for common‑mode and 30 dB for differential‑mode. This performance makes it ideal for environments with high electrical noise, such as industrial machinery, inverters, and switching power supplies.

Typical Applications

• Medical devices (patient‑connected equipment with low leakage requirements)

• Industrial automation and control panels

• Test and measurement instruments

• Telecommunications equipment

• Commercial appliances with sensitive electronics

Construction and Safety

The filter is housed in a nickel‑plated steel case that provides both mechanical strength and EMI shielding. Internal components are encapsulated to resist vibration and environmental stress. Safety approvals include UL 1283, CSA C22.2 No. 8, and EN 60939, ensuring compliance with global standards. The 1383B‑6501 is also RoHS compliant, free from hazardous substances.

With its proven design and rigorous manufacturing, the Eaton 1383B-6501 ensures clean power delivery, reducing equipment malfunction and extending the life of sensitive electronics. It is a trusted choice for engineers who demand reliable EMI suppression in space‑constrained applications.
