LEAD-FREE HEAT ENDURANCE TEST

LEAD-FREE RECOMMENDED REFLOW

1.Operating temperature range

-40 TO + 105°C (Includes temperature when the coil is heated)

2. External appearance

On visual inspection, the coil has no external defects.

3. Terminal strength

After soldering. Between copper plate and terminals of coil. Push in two directions of X.Y

withstanding at below conditions.

Terminal should not peel off. (refer to figure at right)

Applied force: 10N; Duration: 5 Sec

4. Insulating resistance

Over 100MΩ at 100V D.C. between coil and core.

5. Dielectric strength

No dielectric breakdown at 100V D.C. for 1 minute between coil and core.

6. Temperature characteristics

Inductance coefficient (0~2,000)x10-

6 /°C (

-25~+80°C)

inductance deviation within ±5.0%, after 96 hours

7. Humidity characteristics (Moisture Resistance)

Inductance deviation within ±5%, after 96 hours in 90~95% relative humidity at 40 ±2°C

and 1 hour drying under normal condition.

8. Vibration resistance

Inductance deviation within ±5%, after vibration for 1 hour. In each of three orientations at

sweep vibration (10~55~10 Hz) with 1.5mm P-P amplitudes.

9. Shock resistance

Inductance deviation within ±5%, after being dropped once with 981m/s

2 (100G) shock

attitude upon a rubber block method shock testing machine, in three different orientations.

10. Resistance to Soldering Heat: 260°C, 10 seconds (See recommend reflow)

11. Storage environment

Temperature: 0°C~35°C; -40°C~105°C (after mounting on PCB)

Humidity Range: 50% ~ 70% RH

12. Use components within 12 months.

If 12 months or more have elapsed, check solderability before use.
