WSM

●GENERAL CHARACTERISTICS

1.

Operating temperature range: -40 TO + 85°C (Includes temperature when the coil is heated)

2.

External appearance: On visual inspection, the coil has 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) 0.5kg

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).

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.
