Frequently Asked Questions
What is the minimum order quantity for a custom 1 mH choke?
We accept orders as low as 500 pieces for OEM/ODM projects. For standard stock, the MOQ is 100 pieces.
Can you provide a sample before bulk production?
Yes – we ship a free engineering sample (up to 2 units) within 48 hours after you confirm specifications.
What are the typical lead times for 1 mH choke bulk orders?
Standard stock: 5‑7 working days. Custom design: 14‑21 days after design approval.
Do you support drop‑shipping directly to my end‑customer?
Absolutely. We offer FOB, CIF, and DDP options, and can label each unit with your brand.
How do you ensure quality and regulatory compliance?
All chokes undergo 100% in‑line testing, IEC‑type inspection, and are accompanied by CE/FCC/ISO‑9001 certificates.
Mark T., Purchasing Manager – SoundWave Corp. – “The 1 mH choke arrived on schedule, passed our EMC test on first try, and saved us $0.12 per unit.”
Emily R., Technical Director – MedLife Systems – “Excellent technical support; the choke’s temperature stability allowed us to meet ISO‑13485 without redesign.”
David L., Operations Lead – SolarFlex Energy – “Fast 48‑hour prototype helped us beat our product launch deadline by a week.”
