Pentek FILTER 3F11 800000919 EMI Filter Module

This EMI filter module solves real-world noise problems in industrial environments. I’ve seen engineers struggle with erratic sensor readings caused by electrical interference – this device effectively eliminates those headaches by cleaning up power lines feeding PLCs, servo drives, and communication systems.

Real-World Applications

We’ve deployed this filter in environments where precision matters – think CNC machining centers experiencing position errors from motor noise, or packaging lines where sensor glitches caused false rejects. It’s particularly effective in:

• Automation systems with multiple VFDs (Variable Frequency Drives)
• Power distribution units for sensitive test equipment
• Communication racks in manufacturing facilities
• Renewable energy installations with grid-tied inverters

While not a magic bullet, when combined with proper grounding practices, this filter significantly reduces common-mode noise. One customer in Singapore saw a 70% reduction in communication errors after installation.

Our Value Proposition

We maintain this item in our Singapore hub with typical 3-5 business day delivery. Unlike some distributors, we don’t just sell parts – our engineers can help diagnose noise issues and recommend proper filter placement.
