BFCN-4440+
| Part Number | BFCN-4440+ |
| Manufacturer | Mini-Circuits |
| Category | RF Components > RF Filters > Multilayer Ceramic Bandpass Filter |
| Description | 50Ohm SMD Bandpass Filter, 4440MHz Center Frequency, RF Channel Selection & Out-of-Band Interference Suppression,SMD-4P,3.2×1.6mm Package |
Product Overview
The BFCN-4440+ is a compact surface-mount bandpass RF filter designed and produced by Mini-Circuits with center frequency fixed at 4440MHz. Constructed with mature multilayer ceramic dielectric technology, this component achieves low insertion loss inside the target passband and high attenuation for out-of-band low-frequency clutter and high-order harmonic signals. Its miniature SMD outline supports fully automatic SMT pick-and-place assembly for mass PCB production, maintaining stable RF electrical characteristics across a wide operating temperature range. It is widely deployed for channel filtering, frequency screening and signal purification in sub-6GHz 5G equipment, ISM microwave wireless modules and laboratory broadband RF testing instruments.
