For in-stock items, we can ship within 24-48 hours. For custom or out-of-stock items, lead time is typically 2-4 weeks depending on the specific product and quantity. We maintain over 50 million pieces in stock across our global warehouse network to ensure availability.

Yes, all Aishi capacitors distributed by LiTong Group are RoHS compliant and meet international environmental standards. We ensure all products meet environmental regulations including RoHS, REACH, and conflict minerals requirements.

Yes, our certified Field Application Engineers (FAEs) provide comprehensive technical support including application guidance, circuit design, lifetime calculations, and troubleshooting. Our team averages over 10 years of experience in electronics design and component applications.

The CD11 series is Aishi's standard general-purpose aluminum electrolytic capacitor line with a rated life of 2000 hours at rated temperature. The CD110 series is a long-life version with a rated life of 4000-5000 hours at +105°C, making it suitable for applications requiring extended operational life such as LED lighting and automotive applications.

You can request samples through our contact page, by contacting your local sales office, or by emailing samples@elec-distributor.com. We offer sample quantities for most Aishi product series to support your design and testing needs.

Standard Aishi aluminum electrolytic capacitors typically operate from -40°C to +105°C. Some series are available with extended temperature ratings up to +125°C for high-temperature applications. Solid polymer capacitors generally have improved temperature performance with lower ESR at elevated temperatures.

Yes, Aishi capacitors can often serve as direct replacements for other brands. Our cross-reference guides help identify equivalent Aishi parts. In many cases, Aishi capacitors offer improved performance characteristics or cost advantages over competitor parts. Contact our technical team for specific replacement recommendations.

Aishi capacitors are certified to international standards including IEC, JIS, and various safety standards such as UL and CSA. The manufacturing facilities are ISO 9001 and ISO 14001 certified, ensuring consistent quality and environmental responsibility.

LiTong Group provides a standard warranty covering manufacturing defects in Aishi capacitors. The warranty period is typically 12 months from the date of shipment. Our quality assurance processes ensure that all products meet Aishi's specifications before shipment.

Aishi capacitors' operational life depends on applied voltage, ambient temperature, and ripple current. The general rule is that life doubles for every 10°C decrease in operating temperature. We recommend using Aishi's lifetime calculation tools or contacting our FAE team to determine expected operational life under your specific application conditions.
