Installation & Usage Guidelines

1. Pre-Installation Check: Verify inductance value, current rating, and physical dimensions match your circuit design; inspect for damage to leads or core.
2. PCB Preparation: Drill through-holes matching the lead spacing of the toroidal inductor (standard spacing: 5mm to 30mm) and clean the PCB surface to remove debris.
3. Lead Insertion: Insert the tinned leads into the PCB holes, ensuring the toroidal core is positioned flat against the board (avoid tilting to prevent flux imbalance).
4. Soldering: Use a temperature-controlled soldering iron (350-380°C) to solder leads; limit soldering time to 3 seconds per lead to prevent thermal damage to insulation.
5. Post-Soldering Inspection: Check for cold solder joints or short circuits; measure DCR with a multimeter to confirm electrical continuity.
6. Functional Testing: Power on the circuit and monitor inductance stability and temperature rise (max 40°C above ambient under full load).
7. Environmental Protection (Optional): Apply conformal coating for harsh environments (e.g., automotive, industrial) to protect against moisture and vibration.
