The 25M-49S-SR series of passives are high-Q thin-film surface mount components. They are designed for use in RF and microwave circuits and systems where size and performance are critical. The series consists of shunts, attensuators, low pass and high pass filters, as well as hybrid couplers. They are compatible with standard pick and place equipment, and can be mounted on FR4 or other thin-film substrates for high-frequency performance. The series is ideal for applications such as 5G, Wi-Fi, Bluetooth, satellite communications, and automotive where space and performance are important.
