Consumer Electronics Grade 1235 Aluminum Foil for Capacitors

Material Application: Electrolytic Capacitors

Product: 1235 Aluminum Foil

Project Details:

Under the trend of pursuing high efficiency and miniaturization in electronic devices, 1235 aluminum foil for capacitors has become a key material for enhancing circuit performance. As the core electrode of electrolytic capacitors, this high-purity aluminum foil is widely used in consumer electronics, industrial power supplies, and new energy vehicles due to its lightweight, high conductivity, and corrosion resistance, providing stable and reliable energy storage and discharge solutions for devices.

Why is 1235 Aluminum Foil the Ideal Choice for Capacitors?

The exceptional performance of 1235 aluminum foil stems from its balance of purity and processing technology. The material, with a base of over 99.35% high-purity aluminum, achieves uniform thickness through precision rolling technology, while a natural oxide film forms on its surface, providing both conductive and insulating functions. This characteristic allows it to efficiently conduct current while preventing leakage or short circuits. For example, in smartphone charger circuits, capacitors made from 1235 aluminum foil can withstand frequent charge-discharge cycles, ensuring charging efficiency remains stable above 90%.

Applications: From Everyday Devices to Cutting-Edge Technology

Consumer Electronics: In wearable devices like Bluetooth earbuds and smartwatches, 1235 aluminum foil’s ultra-thin flexibility meets miniaturization demands while reducing product weight.

Industrial Power Systems: Solar inverters and industrial UPS systems rely on 1235 aluminum foil capacitors for voltage stabilization. Their high-temperature resistance (-55°C to 105°C) extends the lifespan of outdoor equipment.

New Energy Vehicles: In onboard charging modules and battery management systems (BMS), 1235 aluminum foil capacitors undergo rigorous vibration tests to ensure precise filtering and safe energy transmission under complex road conditions.

Eco-Friendliness and Efficiency Drive Material Innovation

With growing global emphasis on e-waste recycling, the recyclability of 1235 aluminum foil has become a key competitive advantage. Unlike traditional materials, aluminum foil can be remelted after capacitor retirement, reducing production costs and environmental impact. Meanwhile, as market demands for smaller capacitors intensify, 1235 aluminum foil—through surface treatments like nickel plating and passivation layer optimization—further reduces size while enhancing voltage resistance, meeting the needs of high-density applications such as 5G base stations and data centers.
