Two new low Equivalent Series Resistance (ESRLow Equivalent Series Resistance) polymer capacitors from Panasonic are now available at RS. The company advises its POSCAP and OS-CON devices? are ideal for digital and telecommunications applications, and support energy reduction in industrial equipment and automotive systems.
The company points out that its POSCAP is a solid chip capacitor with a sintered tantalum anodeAn electrodeA solid electric conductor through which an electric current enters or leaves in a medium through which current enters any nonmetallic conductor. and a highly conductive polymer cathodeThe negative electrodeA solid electric conductor through which an electric current enters or leaves in a medium of a capacitor.. Adding that its low impedanceThe total opposition that a circuit offers to the flow of alternating current or any other varying current at a particular frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz).. It is a combination of resistance R and reactance X, measured in ohms. and low ESRLow Equivalent Series ResistanceLow Equivalent Series ResistanceLow Equivalent Series Resistance (down to 5 mO) enable?good performance at high frequencyThe number of complete cycles or vibrations per unit of time.

Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. range. The device is claimed to offer very good noise-absorption characteristics, and provides high heat resistance, across a temperature range of between -55°C and 125°C.
The second device, the OS-CON is described as a solid aluminium capacitor containing highly conductive polymer electrolyte material. It can offer low ESRLow Equivalent Series ResistanceLow Equivalent Series ResistanceLow Equivalent Series Resistance, good noise reduction capability and frequencyThe number of complete cycles or vibrations per unit of time.

In addition, this device is claimed to have a long life span of up to 30 years, and can operate efficiently at even the lowest temperatures due to the solid electrolyte. The company adds that these two devices are suitable as a smoothing, backup and bypass capacitorAn alternative name for decouplingA decoupling capacitor is a capacitor used to decouple one part of an electrical network (circuit) from another. Noise caused by other circuit elements is shunted through the capacitor, reducing the effect they have on the rest of the circuit capacitor as it is used to bypass the power supply or other high impedanceThe total opposition that a circuit offers to the flow of alternating current or any other varying current at a particular frequencyThe number of complete cycles or vibrations per unit of time.
