Electromagnetic Filter EB2131936143 250VAC 0.47µF

Electromagnetic Filter EB2131936143 250VAC 0.47µF is a compact EMI suppression component designed for use in 250 VAC electrical systems. It provides capacitive attenuation of high-frequency disturbances and helps improve electromagnetic compatibility (EMC) in appliances and industrial equipment. The filter is intended for integration into AC power lines where reduction of conducted emissions is required and where a 0.47 µF capacitance value meets circuit design needs.

Advantages

This electromagnetic filter offers reliable suppression of high-frequency interference on AC mains lines while maintaining compact dimensions suitable for installation in constrained spaces. Its rated voltage of 250 VAC matches common mains supplies, and the 0.47 µF capacitance provides a balance between effective noise attenuation and minimal impact on normal power delivery. The component is designed to support improved EMC performance of electrical and electronic systems without extensive modification to existing circuitry.

Suitable for

• Appliances with AC mains input requiring conducted EMI suppression
• Industrial control equipment and machinery to reduce electrical noise
• Power supply front-ends where a 0.47 µF suppression capacitor is required
• Retrofit projects to improve EMC compliance of existing devices

Key specifications

• Rated voltage: 250 VAC
• Capacitance: 0.47 µF
• Function: EMI/RFI suppression on AC mains
• Application: Line-side suppression for conducted emissions
• Typical mounting: panel or PCB integration depending on design

How to use

Install the filter in the AC input path following the circuit designer’s layout and safety clearances. Ensure the component is connected with correct polarity or orientation if specified by the equipment design, and place the filter close to the point where mains enter the device to maximize suppression of conducted noise. Verify that the 250 VAC rating and 0.47 µF capacitance are appropriate for the system’s voltage, inrush current, and any regulatory requirements. After installation, perform EMC and safety testing according to applicable standards to confirm effective noise reduction and safe operation.

Usage recommendations

To achieve optimal suppression, pair the filter with appropriate line chokes or additional filtering stages when dealing with severe interference; avoid exceeding the voltage rating and ensure proper creepage and clearance distances in the assembly. If inrush currents are high, consider assessing the impact of the capacitance on startup behavior and, if necessary, use inrush current limiting measures.
