Why Your Current Filters Are Holding Back Production
- Excessive Pass‑Band Ripple – leads to 15‑25 % distortion in audio and medical devices.
- Inconsistent Cut‑off Frequency – variations of ±10 % cause costly re‑testing.
- Long Lead Times – typical 6‑8 week delivery from generic suppliers.
- High Unit Cost – average $4.50 per filter, eroding ROI.
- Limited Customization – no OEM/ODM options for specific inductance‑capacitance pairs.
Result: Production delays, higher warranty claims, and missed market windows.

Frequently Asked Questions
What is the typical lead time for a custom 2nd order low pass filter?
Standard stocked SKUs ship within 48‑72 hours. Custom OEM projects require 2‑4 weeks after design approval, with rapid‑prototype samples available in 5 days.
Can you meet specific cut‑off frequencies outside the 1 kHz‑10 MHz range?
Yes. Our R&D team can design filters from 100 Hz up to 50 MHz. Minimum order quantity for non‑standard ranges is 500 pieces.
What payment terms do you accept for first‑time buyers?
We accept T/T 30 % deposit + 70 % before shipment, or L/C at sight. For qualified distributors, net‑30 terms are available after credit approval.
Do you provide free samples for evaluation?
Yes – up to 5 prototype units per design are shipped free of charge (shipping cost billed to the buyer). No commitment required.
How is after‑sales support handled?
Our technical support desk operates 24 × 5 (UTC +8). We provide on‑site troubleshooting, firmware updates for integrated modules, and a 12‑month warranty.
