Panasonic Industry extends SP-Cap Polymer Capacitor line-up with temperature resistant JX series

Panasonic Industry’s SP-Cap portfolio of Aluminium Polymer capacitors are described as the suitable choice wherever a low ESR would be the primary consideration for identifying the most suitable capacitor.

According to Panasonic Industry, its advanced Solid Polymer technology, the SP-Caps, has proven to be an excellent alternative to multilayer ceramic capacitors (MLCCs) and pure tantalum capacitors. They require less parts and space on the PCB and provide much better performance, especially for modern and complex low-profile electronical devices, with large capacitance up to 820 µF and a ripple current up to 10.2 Arms.

Panasonic Industry has expanded the successful technology further with the new JX series – a high endurance and particularly heat tolerant series.

Coming with the typically low ESR, a large capacitance, a low profile, long life span and high characteristic stability, this latest member of the SP-Cap family stands out with an endurance of 3,000 hours at 125°C and thus promises an exceptional reliability. Its damp heat specifications – 1,000 hours at 85°C 85%RH – render it suitable for demanding outdoor applications.

Shahrokh Kananizadeh, product manager at Panasonic Industry, said: “The JX series has many benefits in a wide range of applications, such as noise reduction or voltage smoothing in base stations, networks, servers, accelerators and industrial equipment. Briefly said, the JX series sets new standards in terms of high temperature reliability – and underlines the superiority of polymer technology for new designs.”

Panasonic Commercializes the JX Series SP-Cap Conductive Polymer Aluminum Electrolytic Capacitors

• The new capacitors improve the reliability of power supply circuits employed in increasingly sophisticated communication base stations, servers, etc.
• They offer long life at high temperature and high humidity endurance
  Osaka, Japan – Panasonic Corporation announced today that its Industry Company has commercialized the JX series of SP-Cap® conductive polymer aluminum electrolytic capacitors [1] with the highest level of reliability in the industry. This new series of capacitors is suitable for use in power circuits for increasingly sophisticated communication base stations such as 5G and servers with increasing data traffic. Mass production of the new capacitors will start in December 2021.

With the evolution of telecommunication equipment, high reliability capacitors with long lifetime and resistance to high humidity in addition to large capacitance are required in power supply designing. By using its proprietary conductive polymer formation technology and manufacturing process technology, Panasonic has achieved high reliability products with three times the lifespan of its existing offerings under high temperature conditions – 3,000 hours at 125℃. They also feature high durability under high temperature and high humidity conditions – 1,000 hours at 85℃/85% (dump-heat steady state). These newly developed capacitors inherit the low ESR [2] (9 mΩ / 100 kHz) and large capacitance characteristics of the SP-Cap® range of conductive polymer aluminum electrolytic capacitors, contributing to the stabilization of power supply.

Panasonic’s highly reliable JX series of SP-Cap® conductive polymer aluminum electrolytic capacitors will contribute to lowering environmental impact, as well as improving the reliability of power supply circuits.

Panasonic plans to expand product lineup of the low ESR, and a variety of the rated voltage and capacitance in JX serires.

   Output-side of low voltage power rail power supply circuits employed in the ICT infrastructure industry such as communication base stations, servers, etc.

Product features:

1. The highest level of reliability in the industry
   Panasonic’s SP-Cap® capacitors adopt stacking structure of capacitors elements using aluminum electrode foils. With the combination of its proprietary conductive polymer formation technology and manufacturing process technology, Panasonic has achieved a high reliability capacitors with endurance of 3,000 hours at 125℃ – three times the lifetime of the company’s existing products -– as well as durability of up to 1,000 hours at 85℃/85% (dump-heat steady state).
2. Excellent product characteristics (low ESR and large capacitance) that contribute to stabilizing power supply
   The newly developed capacitors achieved low ESR (9 mΩ / 100 kHz) and large capacitance characteristics under high reliability and high temperature conditions by using Panasonic’s proprietary technology to reduce resistance of internal elements and adapting large capacitance aluminum electrode foils. In addition, from the viewpoint of high reliability, the ESR specification after the endurance is set within two times the initial specification value.
3. Space-saving and lowering environmental impact
   The newly developed capacitors, with an effective capacitance equivalent to that of MLCCs, enable a reduction in the number of required capacitors. Replacing multiple MLCCs with an SP-Cap® capacitor will save space and enable the miniaturization of equipment, thereby lowering environmental impact through the reduction of materials used.
   Term descriptions:
   [1] Conductive polymer aluminum electrolytic capacitors
   Collective term for aluminum electrolytic capacitors that use a conductive polymer, which is a solid electrolyte, instead of an electrolytic solution. There are two types of structures: the wound-type, as used in conventional aluminum electrolytic capacitors, and the stacking type. Conductive polymers have a high conductivity and excellent low ESR characteristics.

  [2] ESR (Equivalent Series Resistance)
  ESR stands for equivalent series resistance, which is a resistance component on the equivalent circuit of electrolytic capacitors. Capacitors with a lower ESR value allow more ripple currents, as well as exhibit excellent noise absorption.
