Dielectric Laboratories / Knowles High-Frequency Surface Mount Highpass Filters

Dielectric Laboratories / Knowles High-Frequency Surface Mount (SMD) Highpass Filters are fully shielded devices with low loss, high permittivity ceramics. These ceramics provide temperature stability in a small size package (11.43mm x 4.450mm x 2.108mm or 11.43mm x 5.08mm x 2.362mm options). Dielectric Laboratories / Knowles High-Frequency SMD Highpass Filters offer a variety of frequency bands, providing a drop-in solution for high-frequency attenuation. The series features a 50Ω characteristic impedance, 1dB typical insertion loss in the passband, and a -55°C to +125°C operating temperature range.
