A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Filter Network (RC/LC).
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
RC filters use resistors and capacitors, are simpler and cheaper, but have gradual roll-off (20dB/decade). LC filters use inductors and capacitors, provide sharper cutoff (40dB/decade), but are larger, more expensive, and may have resonance issues.
Determine the highest frequency needed in your signal (for low-pass) or lowest frequency to block (for high-pass). Add 20-50% margin. For sensor signals, typical cutoff is 10-100x the signal frequency to remove switching noise while preserving signal integrity.
Standard filters handle up to 50-100V. For higher voltages (220V AC lines), use specially rated components with proper creepage distances and voltage derating (50% of rated voltage for reliability).
