1. Excessive EMI leakage – leads to product failures and costly warranty claims.
2. Overpriced components – average market price 25 % higher than factory‑direct rates.
3. Poor quality control – inconsistent inductance values cause design re‑work.
4. Long lead times – 8‑12 weeks from order to delivery, delaying production schedules.
5. Lack of customization – standard parts cannot meet your specific current‑rating or size constraints.
According to a 2025 IEC survey, 42 % of US manufacturers cite EMI‑related downtime as a top profitability threat. Imagine eliminating that risk.
See how we solve these issues →| Parameter | Value | Unit |
|---|---|---|
| Inductance (L) | 10‑120 | µH |
| Current Rating (Imax) | 5‑15 | A |
| DC Resistance (DCR) | ≤ 12 | mΩ |
| Operating Temp. | ‑40 ~ +125 | °C |
| Size (L×W×H) | 12 × 12 × 5 | mm |
• Audio Power Amplifiers – Reduced hum by 37 % in a high‑fidelity speaker system (Customer: SoundTech Inc.).
• Medical Imaging – Achieved IEC‑60601 compliance for a portable X‑ray unit, cutting redesign cost by $45 k.
• Solar Inverters – Improved EMI immunity, enabling UL‑1741 certification 2 months earlier.
Yes. Our OEM/ODM team can tailor inductance, current rating, core material, and PCB footprint. Lead time for standard customization is 5‑7 business days.
We accept orders as low as 500 pieces for stock items and 1,000 pieces for fully customized designs.
All our chokes are supplied with CE, FCC, RoHS, and IEC‑60601 test reports upon request. FDA‑cleared versions are available for medical applications.
We offer air freight (2‑4 days) and sea freight (15‑20 days). All shipments are DDP (Delivered Duty Paid) to your warehouse.
Free technical consultation for 12 months, replacement warranty for manufacturing defects, and a 30‑day money‑back guarantee on first orders.
Stock is limited to 10 k units per model. Secure your supply chain today.
Risk‑Free Guarantee: Receive a functional sample within 5 days or your money back.
Kevin Turner, Operations Manager, SolarWave Inc. – “The 3‑line choke’s low DCR saved us $12 k in power loss annually. Delivery was on‑time, and the technical support answered every question within hours.”
Linda Chen, Procurement Lead, AudioPro Ltd. – “Custom winding options let us fit the choke into a 5 mm PCB space, something competitors couldn’t achieve. The ROI is evident in our reduced warranty claims.”
Mark Patel, Technical Director, MedEquip USA. – “Xinchangda’s ISO‑9001 processes gave us confidence for FDA‑cleared devices. The first batch passed all compliance tests on the first try.”
