Environmental Specification

Environmental and Test Specifications for Surface Mount Power Inductors

1. Operational Temperature
  • Ambient temperature of - 25°C to +80°C (The coil will dissipated heat from its resistance). Please contact factory if higher temperature is needed.
2. External Appearance
  • On visual inspection, the surface mount power inductors should have no visible external defects.
3. Terminal Strength
  • After soldering, the surface mount inductor/ choke should withstand the following test:
  1. A force of 5N ( 0.15 K GF) is applied for 10 + -2 seconds between copper trace and the soldered coil in the X direction.
  2. A force of 5N ( 0.15 K GF) is applied for 10 + -2 seconds between copper trace and the soldered coil in the Y direction.
  3. The terminal should not peel off when 1 and 2 are executed. Refer to figure at right.
4. Heat Endurance Test
5. Dielectric Strength
  • No di-electric breakdown when a 100V DC. is applied for 1 minute between the coil (winding) and the core.
6. Insulating Resistance
  • Over 100M ohms at 100V DC. between the coil and the core.
7. Inductance Temperature Coefficient
  • (0 ~ 2000) x 10-6 /°C . At ambient tempertaure of -25°C to +80 °C
8. Humididty Test
  • Inductance deviation is within + - 5% after 96 hours in a 90 to 95% relative humidity at 40 + -2°C and a 1 hour drying period under normal conditions.

9. Vibration Test

  • Inductance deviation is within + - 3.0% after a vibration period of 1 hour in each of the 3 orientations sweep vibration (10~55~10Hz) with a 1.5mm peak to peak amplitude.
10.Shake / Drop Test
  • Inductance deviation is within + - 3.0% after a drop down with a 981 m/s2 (100G) shack attitude upon a rubber block type of shock testing machine. Duration of 1 time, in each of the 3 orientations.
