Murata introduces world's first and smallest 01005-size Hi-Q MLCC

Murata today announced the GJM02 series of monolithic ceramic chip capacitors (MLCC) specifically designed for use in high frequency module applications such as for coupling in power amplifiers of cellular phone handsets. Believed to be the world’s first 01005 size (EIA) Hi Q type MLCC, this miniature capacitor measures just 0.4 x 0.2 mm and has both high ‘Q’ and low equivalent serial resistance (ESR) characteristics. Having a high Q value and low ESR is essential for use in VHF, UHF and microwave power amplifier. Together they contribute to improving power amplifier efficiency and lowering power consumption.

Murata targets automotive markets with launch of chip monolithic ceramic capacitors with metal terminals

Murata today announced the KCM series of chip monolithic ceramic capacitors (MLCC) aimed at automotive applications. Equipped with metal pins, the capacitors have been specifically designed to have long-term resilience against substrate expansion and contraction stresses resulting from sharp temperature changes experienced in automotive environments. Also, the KCM/KC3 series offer higher reliability characteristics compared to discrete capacitor elements since they are able to withstand high levels of vibration and mechanical impact associated with such designs. The KCM series suit a wide range of automotive electronic systems, such as DC-DC converters in engine control units (ECU), in conventional automobiles as well as for the growing market for electric (EV) and hybrid electric vehicles (HEV).The series comprises capacitors with nominal operating voltages from 25 to 100 VDC, and with values in the range 4.7 to 22 uF. Measuring 6.1 x 5.3 mm, and with height varying from 2.8 to 6.4 mm dependent on value, these compact capacitors require less board space and have been achieved by stacking capacitive elements.

High reliability metal terminal capacitors from Murata achieve major acoustic noise reduction and are immune to PCB flexure

Hoofddorp, Netherlands: Murata has developed a series of MLCCs with a unique external metal terminal design which reduces problems associated with mounting larger size MLCCs, including acoustic noise production and cracks caused by flexing the PCB. The construction of this series, the KRM series, also allows two capacitors to be mounted on top of each other, doubling the effective capacitance to achieve very high capacitance values inside small footprints. Additionally, this series outperformed traditional MLCCs in heat shock cycle tests.

Murata introduces fail safe ceramic capacitor for automotive applications

Murata today announced the launch of the GCE series of monolithic ceramic capacitors that are less prone to failure due to mechanical stress. With a soft termination of the capacitive element, the mechanical stress induced by board flexing or a wide variation of temperature is less likely to cause the capacitor body to crack. This is achieved by using a conductive resin for the terminations, and increases the body’s ability to absorb such stress. In addition, by using a multi-layer serial capacitor (MLSC) approach to the construction, the GCE series will not easily short-circuit either. This technique uses an internal “floating” plate that creates an equivalent circuit of two capacitors in series. In this way, a short circuit condition is highly unlikely to happen due to component failure. This makes the GCE series ideal for a broad range of automotive applications where safety is crucial.

Murata MLCC reduces flicker and acoustic noise in LED lighting applications

Murata today announced the introduction of a series of capacitors specifically designed to provide DC smoothing and acoustic noise reduction in LED lighting applications. As the market for LED lighting has steadily grown customers have recognized that a capacitive DC bias, that results in less actual capacitive value, and a piezo-electronic phenomenon within capacitors has been the cause of light flickering and acoustic noise. Previously, many designers have avoided the use of ceramic capacitors in LED lighting applications even though they have superior size and higher temperature reliability.

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.
