Surface-Mount Low Pass Filters

Dielectric Laboratories / Knowles Surface-Mount Low Pass Filters (LPFs) incorporate low-loss, high permittivity ceramics to provide minimal performance variation over temperature. These fully shielded components feature a small size and excellent repeatability. They are offered in a variety of frequency bands, which offers a drop-in solution for high-frequency attenuation. Dielectric Laboratories / Knowles Surface-Mount Low Pass Filters are 100% tested and inspected.
