About EMI Feedthrough Filters

EMI feedthrough filters are passive components installed at enclosure entry points to block electromagnetic interference from entering or exiting shielded compartments. Unlike standard capacitors, their symmetrical design provides low-inductance grounding paths for both conductors in a feedthrough configuration.

These filters are essential for compliance with FCC Part 15, CISPR 22, and MIL-STD-461 standards. By attenuating high-frequency noise on power lines and signal cables, they prevent data corruption in sensitive electronics while enabling compact EMC solutions in space-constrained designs.

Frequently Asked Questions

Q: What’s the difference between feedthrough capacitors and standard EMI filters?
A: Feedthrough capacitors mount directly through shielded enclosures, providing lower ESL and superior high-frequency attenuation compared to inline filters.

Q: Can this filter handle 50VAC applications?
A: The 50V rating applies to DC voltage. For AC applications, derate to 70% of DC value (35VAC max).

Q: Is conformal coating compatible with this component?
A: Yes, the nickel-plated brass construction supports common acrylic or urethane coatings.

Q: What torque is recommended during installation?
A: Apply 5-7 in-lbs torque when mounting to prevent deformation of turret leads.

Q: How does temperature affect performance?
A: X7R dielectric maintains ±15% capacitance variance across the rated -55°C to +125°C range.

Q: Can I parallel multiple filters for higher current?
A: Yes, but maintain 5mm minimum spacing between units to prevent mutual inductance effects.
