調達に関する考慮事項

When procuring power resistors, consider the following: verify the actual power rating under your operating conditions, as derating is necessary. Check the temperature coefficient of resistance (TCR) for precision applications. Ensure the resistor’s voltage rating matches your circuit. For high-frequency circuits, select non-inductive types. Request a Certificate of Compliance (CoC) for safety standards. Negotiate payment terms like T/T or L/C, and clarify shipping terms (FOB, CIF). Always order samples before mass production. Maintain a buffer stock for critical components to avoid supply chain disruptions.
