Smyrna, Ga. Murata Electronics is offering three new lines of microchip capacitors that offer small packaging along with improved performance for microwave circuit applications. The CLB and CLG series of single-layer microchip capacitors and GMA series of multi-layer microchip capacitors all feature excellent characteristics at microwave frequencies due to a combination of ceramic technology with monolithic construction, said the company.
These single and multi-layer microchip capacitors were developed for use by design engineers in optical communication circuits, microwave communications circuits, internally matched power amplifier modules for base stations, and LSI/IC packages for built-in applications.
In microwave circuit applications, a single layer, high-frequency microchip capacitor such as the CLB/CLG series is an essential circuit component due to its high quality, low inductance, high self-resonant frequency and mounting performance for matching to the conductor line width, said the company. The CLB/CLG series features an optional pre-coated gold-tin electrode, which provides good die shear strength and makes it easy to mount. The CLB microchip capacitors are available in a capacitance value range of 0.1 pF to 4300 pF. The CLG offers a capacitance value range from 0.5 pF to 200 pF.
Offering low inductance and high density mounting performance makes the multi-layer microchip capacitor a key component in microwave circuit applications. One unique advantage of the GMA series is its small size and wide capacitance value range. The GMA is available in capacitance values from 100 pF to 0.1 μF in X7R, X5R and Y5V dielectrics. The voltage may be as high as 100 volts depending on the capacitance value. The company plans to expand the capacitance range to 0.47 μF in the near future.
The CLB, CLG and GMA series are terminated in gold for easy wire and die bonding. These devices can be mounted by using wire bonding with gold wire or die bonding with gold-tin solder. Please contact Murata for additional information on available capacitance and voltage ratings.
The CLB, CLG and GMA series of microchip capacitors are available immediately. Prices range from $0.20 to $1.00, depending on chip size, series, capacitance value and quantity.
