About EMI Filters

EMI/RFI filters are essential passive components that suppress electromagnetic interference in electronic circuits. They protect sensitive components from external noise while preventing devices from emitting disruptive signals that could cause system malfunctions or compliance failures.

LC network filters like this Murata design use combined inductor-capacitor topologies to create frequency-dependent attenuation. Third-order filters provide steeper roll-off characteristics than lower-order alternatives, making them ideal for applications requiring aggressive noise suppression above 10MHz in constrained spaces.

Packaging Options

Available in Tape & Reel (TR) packaging for automated SMT assembly.

FAQs

Q: Is this EMI filter suitable for automotive applications?
A: Yes, its -55°C to 125°C operating range covers most automotive requirements, though verify against specific OEM standards.

Q: What’s the difference between cutoff frequency and center frequency?
A: Cutoff frequency (10MHz here) indicates where signal attenuation begins, while center frequency applies to bandpass/bandstop filters – this is a low-pass type.

Q: Can I use this for power line filtering?
A: With a 100mA current rating and 16V rating, it’s designed for signal lines, not primary power rails.

Q: Why choose an LC filter over ferrite beads?
A: LC networks provide targeted attenuation at specific frequencies with steeper roll-off, whereas beads offer broadband suppression.

Q: How does the Pi topology differ from other configurations?
A: Pi filters (capacitor-inductor-capacitor) deliver superior high-frequency attenuation compared to simpler L or C filters.

Q: Is ESD protection included?
A: No, this model lacks integrated ESD protection – consider additional circuitry if needed.
