BPF-C59+

Overview

The BPF-C59+ is a surface-mount bandpass filter from Mini-Circuits, designed using lumped LC technology within a shielded case. It operates with a center frequency of 59 MHz and a bandwidth of 30 to 88 MHz. The component features a 50Ω impedance and supports an RF input power range of 0.08W to 5W. It functions within an operating temperature range of -40°C to +85°C. The physical dimensions are 0.87 inches by 0.80 inches by 0.25 inches (22.1mm x 20.3mm x 6.35mm). It utilizes a 14-SMD package for compact integration.
