Vishay Intertechnology unveils a new series of ENYCAP electrical double-layer energy storage capacitors for energy harvesting, power backup, and UPS power source applications. Available in power and energy versions with high stability, the new Vishay BCcomponents 220 EDLC ENYCAP series devices is touted to deliver high power density and capacitance values in small case sizes ranging from 16 mm by 20 mm to 18 mm by 31 mm.
Tailored for industrial, telecom, and PC markets, the polarized energy storage capacitors released are sought to offer power density to 4.1 Wh/kg, capacitance values from 15 F to 40 F, and a max. rated voltage of 2.7 V. 220 EDLC ENYCAP series devices feature very low internal resistance and rapid charge and discharge performance. The through-hole capacitors offer long leads and are RoHS-compliant.
Device Specification Table:
|Capacitance (F)||15 to 35||20 to 40|
|Max. peak current @ +65 °C (A)||25||25 to 35|
|Leakage current after 0.5 h (mA)||6 to 15||8 to 20|
|Stored energy at +65 °C (Wh)||0.015 to 0.035||0.020 to 0.041|
|Specific energy +65 °C (Wh/kg)||2.5 to 3.5||3.4 to 4.1|
Samples and production quantities of the 220 EDLC ENYCAP series devices are exclusively available, with lead times of six to eight weeks for larger quantities.
