LC滤波器使用注意事项

使用注意事项

1. Storage Conditions

This product is applicable to MSL1 (Based on IPC/JEDEC J-STD-020).

To avoid damaging the solderability of the external electrodes, be sure to observe the following points.

  • Store products where the ambient temperature is 15 to 35°C and humidity 45 to 75% RH. (Packing materials, in particular, may be deformed at the temperature over 40°C.)
  • Store products in non corrosive gas (Cl 2, NH 3, SO 2, NOx, etc.)
  • Stored products should be used within 6 months of receipt. Solderability should be verified if this period is exceeded.

2. Handling Conditions

Be careful in handling or transporting products because excessive stress or mechanical shock may break products.

Handle with care if products may have cracks or damages on their terminals, the characteristics of products may change. Do not touch products with bear hands that may result in poor solderability.

3. Standard PCB Design (Land Pattern and Dimensions)

All the ground terminals should be connected to the ground patterns.

Furthermore, the ground pattern should be provided between IN and OUT terminals. Please refer to the specifications for the standard land dimensions. The recommended land pattern and dimensions is as Murata's standard. The characteristics of products may vary depending on the pattern drawing method, grounding method, land dimensions, land forming method of the NC terminals and the PCB material and thickness. Therefore, be sure to verify the characteristics in the actual set. When using non-standard lands, contact Murata beforehand.

4. Notice for Chip Placer

When placing products on the PCB, products may be stressed and broken by uneven forces from a worn-out chucking locating claw or a suction nozzle. To prevent products from damages, be sure to follow the specifications for the maintenance of the chip placer being used. For the positioning of products on the PCB, be aware that mechanical chucking may damage products.

5. Soldering Conditions

The recommendation conditions of soldering are as in the following figure.

When products are immersed in solvent after mounting, pay special attention to maintain the temperature difference within 100°C. Soldering must be carried out by the above mentioned conditions to prevent products from damage. Set up the highest temperature of reflow within 260°C.

Contact Murata before use if concerning other soldering conditions.

Reflow Soldering Standard Conditions (Example)

Please use the reflow within 2 times.

Use rosin type flux or weakly active flux with a chlorine content of 0.2 wt % or less.

6. Cleaning

The total cleaning time of soaking, ultrasonic and steam methods should be within 5 minutes.

Consult with Murata concerning the cleaning solvent. In order to totally abolish ODC (Freon, Trichrolethan), Murata has carried out testing on non-cleaning and water cleaning (water-soluble flux, water-soluble cream solder, water-based cleaning solvent). Therefore, be sure to contact Murata beforehand for details when applying any of the above mentioned cleaning fluid.

The ultrasonic cleaning conditions are indicated below:

  • Cleaning Solution: Pineapple alpha, Water
  • Frequency: 50 to 60 kHz
  • Temperature: <40°C

If the ultrasonic output power is too high, the PCB may resonate and products mounted on the PCB may be damaged. The ultrasonic cleaning conditions may change depending on the size of the vessel and the size of the PCB. Contact Murata regarding conditions other than those stated above.

Be sure to completely dry up products immediately after cleaning.

7. Operational Environment Conditions

Products are designed to work for electronic products under normal environmental conditions (ambient temperature, humidity and pressure). Therefore, products have no problems to be used under the similar conditions to the above-mentioned. However, if products are used under the following circumstances, it may damage products and leakage of electricity and abnormal temperature may occur.

  • In an atmosphere containing corrosive gas (Cl2, NH3, SOx, NOx, etc.)
  • In an atmosphere containing combustible and volatile gases
  • Dusty place
  • Direct sunlight place
  • Water splashing place
  • Humid place where water condenses
  • Freezing place

If there are possibilities for products to be used under the preceding clause, consult with Murata before actual use. As it might be a cause of degradation or destruction to apply static electricity to products, do not apply static electricity or excessive voltage while assembling and measuring.

8. Input Power Capacity

Products shall be used in the input power capacity as specified in this page.

Inform Murata beforehand, in case that the components are used beyond such input power capacity range.
