6. Application Information
6.1 Suitable Applications
- Automotive Electronics
- Precision Power Supply
- Instrumentation
- Testing & Measurement Equipment
- Medical Equipment
- AC, DC low and high frequency sampling circuits (due to inductance <3nH)
- Formation & sorting of battery testing equipment
6.2 Usage Suggestions
- Protect the resistor surface during use to avoid scratches, bumps, oil stains and other defects.
- Do not use sharp tweezers to handle the resistor, as surface scratches may cause resistance drift or product failure.
- Avoid mechanical stress impact on the resistor during installation and use.
- The long-term operating power should be less than the rated power to prevent resistance drift caused by long-term overload.
- Refer to the derating curve when operating under high temperature conditions or poor heat dissipation environment.
- A systematic evaluation is required if the operating conditions exceed the pulse specifications in the maximum pulse energy curve.
- If the resistor is not used immediately after being removed from the packaging, store it in a vacuum environment to avoid poor solderability caused by oxidation.
6.3 Reflow Soldering Profile
- Resistor Surface Temperature Requirements:
- Applicable Solder Composition: Sn-Ag-Cu
7. Storage Instructions
- Storage Temperature: 5℃~35℃
- Storage Humidity: <60% RH (keep as low as possible)
- Avoid direct sunlight.
- Store in a clean, dry environment free of harmful gases (such as HCl, Sulfuric acid, H₂S, etc.).
- Do not remove the resistor from the original packaging unless necessary.
- Shelf Life: At least 1 year under the above storage conditions.
