Murata expands its extensive product offering with high capacitance conductive polymer capacitors

Hoofddorp, Netherlands: Murata has launched its first non-ceramic based capacitor product, the ECAS series of polymer aluminium electrolytic capacitors. The introduction of polymer aluminium electrolytic capacitor technology is the result of Murata’s purchase of Showa Denko K.K.’s (SDK) conductive polymer capacitor business. Polymer capacitors exhibit strong equivalent series resistance (ESR) performance compared to traditional electrolytic capacitors and provide similar characteristics to multi-layer ceramic capacitors (MLCCs). The ECAS series allows Murata to greatly expand its high capacitance offerings, giving customers a full range of capacitor solutions. Markets for the ECAS series capacitor include computer, digital audio visual and telecom for overall power management.

Murata develops world's smallest 10μF, 25V rated monolithic ceramic capacitor

Hoofddorp, Netherlands: Murata has developed a 1608-size 10μF monolithic ceramic capacitor, the GRM188R61E106M, which is the world's smallest with a 25V rating. Compared to previous 10μF/25V models, the new capacitor is approximately 60% smaller in volume, contributing to equipment downsizing. Further, its capacitance has been increased ten-fold compared to previous Murata capacitors with the same case size, rated voltage and temperature characteristics.

World's first JEITA RCX-2326 compliant MLCCs from Murata achieved with advances in capacitor construction

Hoofddorp, Netherlands: Murata's GW series of multilayer ceramic capacitors is the world's first to comply to the Japanese standard JEITA RCX-2326. This standard specifies capacitance under actual operating conditions including temperature and DC voltage. Murata has succeeded in achieving higher capacitance with the GW series under these conditions compared with previous models of multilayer ceramic capacitors. The GW series is therefore ideal for decoupling capacitor use in power supply circuits for low voltage driven devices and CPUs, FPGAs and similar applications.

Murata designs World's thinnest embedded capacitor for substrates featuring high capacitance

Hoofddorp, Netherlands: Murata has introduced the GRU series, the world’s thinnest embedded monolithic capacitor for substrates. Using advanced ceramic technology, the new 0402 size capacitor, measuring only 1.0mm x 0.5mm x 0.15mm, is built into the substrate for placement below integrated circuits (ICs) and other electronics. The GRU series was developed using Murata’s leading-edge dielectric material expertise to achieve the world’s lowest profile at 150µm with a sophisticated external electrode formation to reduce the component’s thickness. Since this capacitor is designed to be mounted within the PCB substrate, it also enhances equipment performance by reducing wiring inductance.

Increased capacitance and lower cost for Murata's X2-class safety capacitors

Hoofddorp, Netherlands: Murata has increased the capacitance and reduced the cost of its GB series of monolithic ceramic capacitors for power supply primary circuits. These parts are the first monolithic capacitors aimed at power supply primary circuit applications to achieve 56nF capacitance. The cost was also reduced by 15% over previous models by replacing the precious metals like silver that were used for the electrodes with a base metal such as nickel.

Murata GJ8 series of low-profile capacitors reduces acoustic noise by up to 30dB

Hoofddorp, Netherlands: Murata's GJ8 series of multi-layer ceramic chip capacitors (MLCCs) has been specifically developed to reduce acoustic noise in consumer and industrial electronics applications. Sound can be generated by the MLCCs at the input to the DC-DC converter in a notebook PC, or by capacitors in the control circuit of the LCD module in a mobile phone. This problem is caused by the expansion and contraction of the dielectric element in some MLCCs, which causes the PCB to vibrate at the amplitude of the voltage applied. When the frequency of the voltage applied approaches audio frequencies, a noise can be heard.

Murata's Power MONO ceramic capacitor saves board space in Hybrid Electric Scooter application

Hoofddorp, Netherlands: Murata announces that its Power MONO ceramic capacitor has been designed into a hybrid electric scooter. Power MONO ceramic capacitors are much more compact than their film or aluminium electrolytic counterparts and feature high allowable ripple current. Further, Murata designed innovative metal terminals for the Power MONO series that prevent cracking in the ceramic material when exposed to mechanical stress.

Murata’s environmentally-friendly tape packaging for ultra-small 01005 chip capacitors is 90% cleaner

Hoofddorp, Netherlands: Murata’s GRM02 series of 01005 chip capacitors is now available in W4P1 plastic tape packaging. This new tape is 4mm wide and has a pitch of 0.1mm, saving around 75% of the volume of packaging material waste compared to the previous tape packaging. As the new tape is plastic, it reduces the amount of fluff and dust produced by at least 90% over the old paper tape. Class 1000 clean mounting processes can now be applied to the GRM02 series, so that more applications can take advantage of the series’ low ESR, low ESL and ultra-small size.

Murata’s high-Q low-ESR MLCCs reduce power consumption in RF applications

Hoofddorp, Netherlands: Murata’s GQM series of high-Q multilayer ceramic chip (MLCC) capacitors features low ESR and high Q at VHF, UHF and microwave frequencies. Low ESR – 0.1 Ohms at 1GHz for a typical 10pF capacitor – helps reduce power consumption in mobile phones, basestations and telecommunications equipment, particularly RF power amplifiers. The series comes with high voltage ratings up to 250V in 0603 packaging, and up to 100V in 0805 packaging. 0805 versions rated at 250V are under development.
