Murata's High Frequency - High Q Capacitors
	GJM, GQM and ERB Series

The high-frequency communication infrastructure market is continuously expanding. The downsizing trends for circuit module designs have increased the requirements for lower profile and power consumption, high frequency with low-loss Hi-Q capacitors. Murata has the solution to meet these demands offering three series of RoHS compliant C0G characteristics, such as the GJM, GQM, and ERB series.

GJM Series

GJM Series: The Murata GJM series is a Hi-Q ultra small capacitor series for high frequency applications in the 500MHz to 10GHz range, suitable for VCO and PA module applications. The GJM series is made with copper electrodes as a cost effective solution for low ESR and power consumption due to the high Q (low loss) performance. A variety of tight tolerance versions are available, offered in EIA sizes 0201 and 0402 with a capacitance range of 0.2 to 20pF. Features Applications Size: 0201 and 0402 Voltage: 6.3, 25, 50VDC Cap. Range: 0.2 to 20pF Internal Electrode: Cu Termination: Cu + Ni/Sn Plating ESR: Very low Power: Low Power (up to 5W) Freq. Range: 500MHz - 10GHz Temp.

GQM Series

GQM Series: A copper based internal electrode makes the GQM series highly resistant to frequency, which can be used from 500MHz to 10GHz. The copper electrodes allow for ultra low ESR, Hi-Q in the GHz frequencies and high RF current handling capability. This series is the best choice for high performance; high power RF designs requiring voltages up to 250VDC. A variety of tight tolerance versions are available, offered in EIA sizes 0603 and 0805 with a capacitance range of 0.1 to 100pF. Features Applications Size: 0603 and 0805 Voltage: 50, 100, 250VDC Cap. Range: 0.1 to 100pF Internal Electrode: Cu Termination: Cu + Ni/Sn Plating ESR: Ultra Low Power: High Power (>15W) Freq. Range: 500MHz - 10GHz Temp. Char.: C0G (-55°C to 125°C with 0 ±30ppm/ °C)  • Base Stations for Cellular  • Broadcast Satellites  • Cable TV & Telecommunication    Networks  • GPS  • Bluetooth  • TV Set-Top Boxes

ERB Series

ERB Series: Exhibiting a capacitance range of 0.5 to 1,000pF, the ERB series of capacitors comes with higher Q and lower ESR which is better than the standard products of equivalent packages. For high performance, medium power RF designs, this series offers low ESR in the 1MHz to 1GHz frequency range. The temperature stability of the C0G dielectrics ensures low power dissipation. The ERB series is designed with precious metal inner electrodes. These surface mount capacitors are available in voltages up to 500VDC in a 1210 EIA size. Features Applications Size: 0603, 0805, and 1210 Voltage: 50, 100, 250, 300, 500VDC Cap. Range: 0.5 to 1000pF Internal Electrode: Pd Termination: Ag + Ni/Sn Plating ESR: Low Power: Medium Power (5-15W) Freq. Range: 1MHz - 1GHz Temp. Char.: C0G (-55°C to 125°C with 0 ±30ppm/ °C)  • General Purpose High Frequency    Circuits  • Wireless Equipment  • High Frequency Radios  • Broadcast Satellites  • RF & Base Station Power Amplifiers
