Elna Super Capacitors
Elna Super Capacitors are electric double layer capacitors (EDLC) produced by A&S Semiconductor Co., Ltd. in Chengdu, China. These devices are designed for high-cycle energy storage with low equivalent series resistance (ESR), offering rapid charge and discharge capabilities. Available in radial lead and surface mount (SMD) packages, they operate across a wide voltage range and are built using activated carbon electrodes, aluminum cases, and organic electrolyte. The product is engineered for industrial, automotive, and renewable energy applications where reliability under stress is critical.
The capacitor core uses high-purity activated carbon with a specific surface area typical of commercial EDLCs, ensuring high capacitance density. The organic electrolyte is formulated for stability between -40°C and +85°C, a standard operating range for industrial-grade supercapacitors. The aluminum casing is anodized for corrosion resistance, and the terminals are tin-plated for solderability. Unlike lithium-ion batteries, these capacitors do not degrade significantly after 500,000 cycles, making them suitable for frequent power buffering.
Buyers in the automotive, telecom, and solar inverter industries use these capacitors for peak power support, memory backup, and motor start-up assistance. The capacitors are sourced by OEMs requiring long-term reliability without maintenance. Trade terms are typically FOB Chengdu or Shanghai, with minimum order quantities aligned with production batch sizes. Packaging is anti-static tray-based for SMD and bulk tube for radial types. Buyers should request cycle life data and ESR measurements for their specific voltage rating before procurement.
| Product Type | Electric Double Layer Capacitor (EDLC) |
| Capacitance Range | 10 mF to 10 F (standard commercial range for EDLCs) |
| Voltage Ratings | 2.5 V, 2.7 V, 3.0 V, 5.5 V (typical for organic electrolyte EDLCs) |
| Equivalent Series Resistance (ESR) | Typical 10 mΩ to 150 mΩ, depending on capacitance and voltage |
| Operating Temperature | -40°C to +85°C (standard for industrial-grade organic electrolyte) |
| Cycle Life | Typical > 500,000 cycles at rated voltage and 25°C |
| Package Type | Radial lead, SMD (surface mount) variants |
| Electrode Material | Activated carbon, standard for EDLCs |
| Electrolyte | Organic solvent-based, typical for non-aqueous supercapacitors |
| Case Material | Anodized aluminum, standard for high-reliability EDLCs |

Sourcing Elna Super Capacitors from A&S Semiconductor Co., Ltd. - China Import Guide
Before ordering Elna Super Capacitors from A&S Semiconductor, verify the capacitance tolerance, ESR value, and leakage current for the exact part number and voltage rating. Request a sample batch for testing under your operating conditions, especially if used in high-ripple or high-temperature environments. Confirm that the packaging is anti-static and that each unit is labeled with batch and date codes for traceability.
Logistics are typically handled via FOB Chengdu or Shanghai port. Lead time is generally 4 - 6 weeks for standard orders, depending on production scheduling. Incoterms are commonly FOB, though CIF and DDP are available on request. Payment terms usually require 50% advance, with balance against bill of lading. Buyers should confirm container loading conditions and request humidity control documentation if shipping to tropical regions.
For quality control, request a certificate of conformity with test data for capacitance, ESR, leakage current, and cycle life. Use an LCR meter to verify capacitance and ESR upon receipt. Check for physical damage to leads or casing, and inspect solderability on SMD units. Retain a sample from each shipment for future failure analysis. Ensure the supplier provides a material compliance statement for RoHS and REACH.
