About Ceramic Filters

Ceramic filters provide essential frequency control in modern RF systems by selectively passing or blocking signal bands. Their piezoelectric properties enable precise resonant behavior without external power. Compared to LC filters, ceramic designs offer superior size efficiency, temperature stability, and rejection ratios – critical for dense PCB layouts.

Low pass filters specifically suppress electromagnetic interference (EMI) from harmonics and digital noise, preventing signal degradation in receivers/transmitters. They are indispensable in FCC/ETSI-compliant designs across wireless infrastructure, industrial automation, and consumer electronics where spectrum cleanliness impacts performance.

Packaging Options

Available in Tape & Reel (T/R) packaging compatible with automated SMT assembly lines. Bulk reel quantities ensure production continuity for high-volume orders.

Frequently Asked Questions

Q: What’s the attenuation slope for this filter?
A: Exact roll-off characteristics are in Johanson’s datasheet. Typical ceramic LPFs achieve >30dB rejection at 1.5x cutoff frequency.

Q: Is this compatible with lead-free reflow processes?
A: Yes, Johanson designs all SMD components for RoHS-compliant assembly with peak temperatures up to 260°C.

Q: Can I use this for 868MHz applications?
A: While possible, performance may degrade. For optimal results, select a filter matched to your target frequency.

Q: Does PCX provide samples?
A: Yes! Contact our support team for sample requests and evaluation guidance.

Q: How do ceramic filters compare to SAW alternatives?
A: Ceramic offers higher power handling and temperature stability; SAW filters provide steeper skirts. Choice depends on application priorities.

Q: What’s the typical lifespan?
A> Johanson ceramic filters exceed 100,000 hours MTBF under rated conditions due to solid-state construction.
