Exxelia high-Q ceramic capacitor series is designed for medical, scientific and industrial uses

05 May 2020

New Yorker Electronics has released the newest series of Exxelia CH high-Q RF and microwave capacitors. The CH series offers capacitance options ranging from 0.1 pF to 1,000 pF with voltages from 50 V to 1,500 V. Designed for use in medical (MRI), scientific, industrial and cellular base stations, the series is available in low ESR, ultra high-Q and high self-resonant frequencies.

The Exxelia CH high-Q ceramic capacitor released by New Yorker Electronics is a chip capacitor for surface mounting. It is available with non-magnetic copper or nickel barrier and tinning. Ribbon leads are also available for surface mounting. Circuit applications for the series include DC to RF Conversion, matching networks and tuning, coupling and DC blocking.

The CH series is one of several Exxelia MLCC capacitors supplied by New Yorker Electronics, and all are designed with P100 or ultra-stable NPO dielectric. For high power, high voltage applications such as MRI, NMR, RF generators for laser, plasma applications, power filters, Exxelia has developed the CP series and CL series.

The Exxelia NHB series is a complete high-Q range of multilayer ceramic chip capacitors (MLCCs) based on NPO dielectric material. The material provides a very high self-resonant frequency and limits the parasite parallel resonant frequencies. NHB series particularly fits for high power and high frequency applications such as cellular base station equipment, broadband wireless service, point-to-point/multipoint radios and broadcasting equipment.

The Exxelia CNW series is a multi-layer ceramic capacitor for HF and RF applications. Designed primarily for power communications, these chip capacitors are available in a wide range of solderable terminations. Lead options include gold on nickel barrier, dipped nickel barrier, silver ribbon leads or tinned copper leads.

Features

Important features of the Exxelia SH series of RF capacitors include it having the lowest ESR in its class with the highest working voltage in its class (1,500 V). The series is used in cellular base station equipment, broadband wireless service, point-to-point and multi-point radios and RF generators.

The Exxelia SHR-SHD series is a 500 V reverse geometry capacitor with a very high self resonance frequency. This enhanced reliability MLCC with nickel barrier and tinning has an operating temperature up to 175° C. The Exxelia SPT519, CAW and CEW series have a very high volumic power while demonstrating low losses. Designed for military markets, these dielectric power ceramic capacitors are used in power communications.
