Cylindrical RF Microwave Resistor

Manufacturer: Guangdong Qingda Electronic Technology Co., Ltd

Product Overview

Cylindrical (rod‑type) RF microwave resistor adopts high‑purity alumina ceramic cylindrical substrate with precision thin‑film resistive layer, specially optimized for radio frequency and microwave circuits. The compact rod‑shape structure greatly reduces parasitic inductance and parasitic capacitance, delivering stable impedance characteristics across broad GHz frequency bandwidth. Compared with traditional wire‑wound and general axial resistors, it achieves lower signal reflection and flat frequency response, ideal for high‑frequency signal processing scenarios.
Guangdong Qingda Electronics provides complete series of cylindrical RF microwave resistors, covering multiple power grades and resistance values. Support standard bulk order as well as customized development for special frequency, impedance and dimension requirements. All products comply with RoHS environmental standards.
