Reliability Testing
| Parameter | Condition |
| Operating Temperature | -30 to +100 (Contain Heating coil) |
| Appearance Inspection | No external defects by visual inspection |
| Terminal Strength | After soldering, between copper plate and terminals of coils, push in two directions of X, Y with standing 10N(1.02kg) for 10+/-2 sec. Terminals should not peel off. |
| Heat endurance of reflow soldering | Refer to figure |
| Insulating resistance | Over 100 M at 100V D.C. between wire and core. |
| Dielectric Strength | Apply at 0.5KV 3mA for 1 minute between wire and core. |
| Temperature characteristics | Inductance coefficient (0~2,000) 10 / (-30 ~ +100 ) |
| Humidity characteristics | Inductance deviation within 10%, after 96 hours in 90~95% relative humidity at 40 2 and 1 hours drying under normal condition. A test is made under the above mentioned condition, and it is kept for 2 hours in the normal. |
