Answers to common procurement and technical inquiries regarding polarized capacitors.
A: For standard items, we ship within 3-5 days. For custom OEM/ODM projects, our R&D team delivers samples in 7 days, with mass production starting within 10-15 days after approval.
A: Yes. We offer free samples for qualified buyers. You only need to cover the express shipping cost. This allows you to verify ESR, leakage, and fit on your PCB before committing.
A: Our automated lines use laser marking for permanent, high-contrast polarity indicators. We also implement 100% visual inspection to prevent reverse-polarity installation errors by your assembly line.
A: We accept T/T (Telegraphic Transfer), L/C (Letter of Credit) for large orders, and PayPal for sample purchases. Typical terms are 30% deposit and 70% before shipment.
A: Yes, our medical-grade series complies with relevant safety standards and provides full material declarations (IMDS) required for FDA registration and audits.
Don't wait for production delays. With our polarized capacitor inventory ready for immediate dispatch, you can reduce costs and improve quality simultaneously.

"We struggled with leakage current issues in our medical power supplies for months. Switching to Xinchangda's high-reliability polarized capacitors reduced our field failure rate by 45% in the first quarter. Their engineering team is incredibly responsive."
"The cost savings on our BOM were significant—about 18% lower than our previous supplier—without compromising on the 105°C temperature rating we need for our inverters. Delivery was exactly on time."
"For our high-fidelity audio crossovers, component consistency is everything. Xinchangda's polarized capacitors show excellent batch-to-batch consistency. The OEM design support helped us miniaturize our PCB design."
