Product Description
Product Overview
This UU9.8-10mH Line Filter is designed for filtering circuits. It offers a stable inductance of 10mH with a maximum deviation of 0.5mH and a direct current resistance of 1.2 MAX. The filter operates within a temperature range of -25C to +85C and is suitable for general electronic equipment applications. Key electrical characteristics include a rated current of 0.5A with a temperature rise not exceeding 45C, an insulation resistance of 100M MIN at DC500V, and withstand voltages of AC1.0KV (COIL-COIL) and AC0.8KV (COIL-CORE).

Recommended Soldering Conditions
Applicable soldering process: Reflow soldering.
Storage Methods
Storage Period: Within 6 months from the date of delivery to ensure solderability and packaging condition. If storage exceeds 6 months, confirm solderability before use.
Storage Conditions:
- Temperature: -5 ~ +30
- Humidity: 30~70%RH
- Avoid rapid changes in temperature and humidity.
- Do not store in chemical atmospheres (e.g., sulfurous acid gas, alkaline gas) to prevent poor solderability and corrosion.
- Store on pallets to protect from humidity and dust.
- Avoid heat shock, vibration, and direct sunlight.
Precautions For Use
- The manufacturer is not liable for equipment failure when using the product in applications other than general electronics devices.
- This specification guarantees the quality of the component as a single unit. Thorough evaluation in the application circuit is required.
- Do not apply excessive vibration or mechanical shock.
- Avoid touching the coil with sharp objects (e.g., tweezers) to prevent wire breakage.
- Do not apply excessive stress during mounting to prevent core breakage.
