Conductive Polymer Hybrid Aluminium Electrolytic Capacitors ZE / ZA / ZK Series

Lytic meets Polymer. It brings together low ESR characteristics of specialty polymer capacitor and the low leakage current of aluminium electrolytic capacitor. The series shows a compact design, high reliability of the specialty polymer capacitor and the safety of the aluminum electrolytic capacitor.

Polymer Capacitors: SP-Cap Polymer Aluminum

SP-Caps are Surface Mount Aluminum Electrolytic Capacitors that use a conductive polymer as their electrolyte material. SP-Caps are primarily used as input and output capacitors for DC/DC converters due to their ultra low ESR values. Panasonic SP-Caps offer excellent performance for moderate to high capacitance and voltage values at low cost

Available in both surface mount and through hole types, the OS-CON product line spans several Series of Solid Electrolyte Aluminum Capacitors, which include the SVP, SVPC, SVPF, SVPE, SEP, SEPC, and SEPF Series. OS-CON Capacitors utilize aluminum and a high conductivity polymer material to offer low ESR, excellent noise reduction and ripple current capabilities. OS-CON parts are characterized by a long life span and minimal changes in ESR throughout the entire rated temperature range. Ideal for applications that require the high-voltage, high-capacitance.

Aluminum Electrolytic Capacitors

Electrolytic capacitors use an electrolyte to achieve a larger capacitance than other capacitor types. However, there are several drawbacks to this technology, including low rated ripple current, wide value tolerances, high ESR (equivalent series resistance) and a limited lifetime. A poorly chosen component costing cents can lead to a system failure just as surely as a complex ASIC or microprocessor. Therefore it is prudent to pay attention and give due diligence to the selection of the capacitor, just as any other component. Panasonic Surface Mount Aluminum Electrolytic Capacitors and Leaded Radial Aluminum Electrolytic Capacitors are available in a broad range of voltage ratings and capacitance values. Featuring low ESR, high ripple current, long service life and operating temperatures up to 125°C, they can be used in many applications including A/V, telecommunications, automotive and industrial control equipment.

Electric Double Layer Capacitors (Gold Capacitor): HL Capacitors

Electric double layer capacitors (EDLC) - also known as Gold Capacitors, have moved increasingly into research and development's focus recently because of their power delivery performance that perfectly fills the gap between electrolytic capacitors and traditional batteries. This attention is predominantly coming from applications in portable electronics devices, electric vehicles, bulk electricity storage at power stations and "load levelling" of renewable sources such as solar energy and wind power. The complex challenges of future decentralized energy supply can only be met on the basis of novel hybrid electrical storage technologies. EDLCs have high power density, faster charge/discharge capability, and wide operating temperature compared to batteries. Since they store energy electrostatically, they can pass through hundreds of thousands of charge-/discharge cycles without losing capacitance.

HL Series capacitors offer low resistance combined with guaranteed long life over a wide temperature range, down to -40degC and extending to +65degC. Panasonic HL Series gold capacitors are wound radial lead type devices, which achieve far better capacitance compared to aluminium electrolytic capacitors (up to 1,000 times greater) and superior charge and discharge performance compared with secondary batteries. The further benefit of a rapid change and discharge cycle, which can be performed over 100,000 times, makes Panasonic HL Series ELDCs ideal for applications such as backup power supplies for servers and storage devices, auxiliary power supplies for solar-powered products including street lighting, and driver-assist for motors and actuators in a variety of markets. Maximum operating voltage for the HL Series is 2.7VDC and nominal capacitance range 50 F to 100 F. These ELDCs are also guaranteed at temperatures as low as -40degC, where capacitance change is ± 30% of initial measured value at +20degC. and internal resistance ≤ 7 times of initial specified value. Both the 50F device and the 100F device in the HL Series are guaranteed for a life of 2,000 hours at +65degC. With large capacitance values due to the use of activated carbon for the electrode, HL Series EDLC "Gold Capacitors" sit between aluminium electrolytic capacitors and secondary battery cells in terms of capacitance and offer unique advantages over both, being highly-reliable with very rapid charging/discharging and virtually no limit on the number of charging cycles. As well as long operating life over low temperatures, HL Series components are RoHS compliant, so there are no recycling or accidental leakage issues.

Film Capacitor

Reliability and maintainability are two basic requirements for a proper operation of a system and is mainly related to the technological characteristics of the components composing it. Capacitors are widely used for dc links in power converters to balance the instantaneous power difference between the input source and output load, and minimize voltage variation in the dc link. Such configurations cover a wide range of power electronics applications, such as in wind turbines, photovoltaic systems, motor drives, electric vehicles and lighting systems. With more stringent reliability constrains brought by automotive, aerospace and energy industries, the design of dc links encounters the following challenges: a) capacitors are one kind of the stand-out components in terms of failure rate in field operation of power electronic systems b) cost reduction pressure from global competition dictates minimum design margin of capacitors without undue risk; c) capacitors are to be exposed to more harsh environments (e.g., high ambient temperature, high humidity, etc.) in emerging applications and d) constrains on volume and thermal dissipation of capacitors with the trends for high power density power electronic systems.

All these constrains are addressed by the Surface Mount Film capacitor portfolio of Panasonic which stand out due to following characteristics :

• stable capacitance and temperature characteristics
• tight tolerances
• low ESR
• low dissipation factors
• no shock noise
• no piezoelectric effect
• no audible noise
