Frequently Asked Questions

They suppress high-frequency noise on power lines to protect sensitive electronics. They are ideal for industrial, medical, and test equipment applications.

They use inductors and capacitors to block unwanted RF signals. This prevents noise from affecting circuit performance and system reliability.

FCL-66 filters cover 5–300A, while FCL-660 supports higher currents for more demanding applications. Ratings depend on the specific model used.

Defense, medical, industrial automation, telecom, and power electronics industries widely use these filters. Any sensitive electronics benefit from EMI reduction.

They typically support AC and DC voltages from 120V up to 600V, depending on model. Some models are rated for specialized high-voltage systems.

Yes, they are designed for EMC compliance and integration into shielded enclosures. This ensures accurate testing and minimal EMI leakage.

Insertion loss ranges from 40 dB to over 100 dB depending on frequency and model. Higher attenuation provides stronger EMI suppression.

Sealed designs protect internal components from moisture, dust, and environmental contaminants. This ensures long-term stable performance in harsh conditions.

Yes, they are compatible with sensitive medical devices and high-power industrial systems. They prevent EMI from affecting critical operations.
