FN2070A-3-06

Overview

The Schaffner FN2070A-3-06 is a single-phase, two-stage EMI/EMC power line filter designed for chassis mounting. It supports AC voltages of 110V and 250V with a rated current of 3 A. The component operates within a frequency range of DC to 400 Hz and features faston (quick connect) terminals. Key electrical parameters include an inductance of 9.8 mH, capacitance of 0.47 µF, and a maximum leakage current of 734 µA. It functions reliably across a temperature range of -25°C to +100°C.

Feature Summary

• Provides effective attenuation of electromagnetic interference through a two-stage filtering architecture.
• Designed for secure installation via chassis mount configuration with quick-connect terminals.
• Capable of operating in environments ranging from -25°C to +100°C.

Applications

• Power supply input stages for electronic equipment
• Industrial control systems requiring EMI suppression
• Medical devices adhering to strict EMC standards

Procurement Notes

Verify the specific suffix code against official TE Connectivity / Schaffner documentation to confirm terminal type and certification status. Ensure the application voltage and current ratings align with system requirements before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when a compact, single-phase filter is required for 3 A applications up to 250 VAC. The two-stage design offers higher attenuation compared to single-stage alternatives. Verify that the chassis mounting style and faston terminal pitch match the PCB or wiring harness layout constraints.

Part Context

This component belongs to the FN2070 series of AC/DC chassis filters manufactured by TE Connectivity / Schaffner. The series is engineered for general-purpose EMI suppression in various electronic applications. The 'A' variant typically denotes specific internal component configurations within the broader product family.

Replacement Considerations

Consult official substitution guides for equivalent performance. Potential alternatives may include other Schaffner models with matching current and voltage ratings, provided terminal styles and dimensions are compatible.
