Do you understand Polymer and Hybrid Capacitors?Follow article
Capacitors may seem simple enough but specifying them has actually grown more complex in recent years. The reason why comes down to freedom of choice. The universe of capacitors has expanded over the past few years, in large part because of capacitors designs that take advantage of advances in conductive polymers. Panasonic has created the Polymator tool for calculation and selection purposes:
Panasonic Automotive & Industrial Systems Europe manufactures Capacitors in a broad range of technologies that can be used in the most demanding applications. OS-CON parts are characterized by a long life span and minimal changes in ESR throughout the entire rated temperature range. POSCAP (Tantalum Polymer) parts demonstrate a high reliability and high heat resistance, making them the ideal Chip Capacitor for digital, high-frequency devices and more. The SP-Cap (Aluminum Polymer SMD) line from Panasonic consists of multiple series that offer capacitance range up to 560µF, voltage range from 2V to 16V, and the lowest ESR/impedance in the industry, achieving very good noise suppression and transient response. Unlike MLCCs, SP-Caps are free from temperature drift and DC/AC bias characteristics. The EEH-ZA and the EEH-ZC series take the benefits of both electrolytic and aluminum polymer capacitor technologies and combine them, producing a capacitor with low ESR, low leakage current, high ripple current and smaller case sizes.
Panasonic OS-CON™ Aluminum-Polymer Capacitors
Panasonic OS-CON™ Aluminum-Polymer Solid Capacitors utilize aluminum and a high conductivity polymer material to offer low ESR, excellent noise reduction and ripple current capabilities. The OS-CON Aluminum-Polymer Solid Capacitor product line consists of several series (SVP, SVPC, SVPF, SVPE, SEP, SEPC, and SEPF Series) that include products characterized by a long life span and minimal changes in ESR throughout the entire rated temperature range. The OS-CON series offer very low ESR (down to 5mΩ), capacitance range up to 2700µF, and voltage range from 2VDC to 50VDC.
Panasonic POSCAP™ Tantalum-Polymer Solid Capacitors
Panasonic POSCAP Tantalum-Polymer Solid Capacitors achieve stable capacitance at high frequency and temperature, in addition to low ESR/ESL. Available in several series that include solid electrolyte chip capacitors (TPE, TQC, TPF, TPSF, TPB, TPC, TPG, and TPU), the POSCAP tantalum-polymer capacitor product line from Panasonic utilizes a sintered tantalum anode and a proprietary high conductivity polymer for a cathode. This innovative construction and processing yield the lowest ESR level in polymer tantalum technology and exhibit excellent performance in high frequency applications. POSCAP capacitors also offer high reliability and high heat resistance, high volumetric efficiency for capacitance, and availability in various compact sizes for a small PCB footprint. This series is ideal for digital, high-frequency devices, and more.
Panasonic SP-Cap Polymer Aluminum Capacitors
Panasonic Electronic Components SP-Cap Polymer Aluminum Organic Capacitor is a surface mount aluminum electrolytic capacitor that uses a conductive polymer as its electrolyte in layered aluminum construction. The SP-Cap product line from Panasonic consists of multiple series that offer capacitance range up to 560µF, voltage range from 2V to 16V, and the lowest ESR/impedance in the industry, achieving very good noise suppression and transient response. Unlike MLCCs, SP-Caps are free from temperature drift and DC/AC bias characteristics. In addition, voltage deration is not needed in SP-Caps, as in tantalum capacitors, due to their safety features. SP-Caps are the perfect solution for input and output capacitor for various DC/DC converters.
Panasonic Hybrid Aluminum Electrolytic Capacitors
Panasonic Hybrid Polymer Aluminum Electrolytic Capacitors take the benefits of both electrolytic and polymer capacitor technologies and combine them, producing a capacitor with low ESR, low leakage current, high ripple current and smaller case sizes.
