Measurements of Fixed Inductors
Maximum Allowable Current
The maximum allowable current is a DC Current which causes initialinductance to decrease by 10% or
30%. Or coil temperature to rise by 20°C or 40°C, whichever is smaller. (Reference ambient temperature:
20°C)
Solderability
After immersion of terminals in flux for 5 to 10 seconds, dip theterminals in the solder bath at 245±5°C for
2±0.5 seconds. Makecertain that more than 3/4 of the surface of the terminals are coatedwith new solder.
Dry Heat Test
The change in inductance, if any, is measured after exposure to 85±2°C in a test chamber for 500±12 hours
and for 1 to 2 hours at room temperature.
Shock Tests
The change in inductance, if any, is measured after the following tests.
● Free Fall Drop Test: A specimen coil is mounted on a test board and dropped freely 3 times
from a height of 1 meter.
● Impact Tester: A specimen inductor is mounted on a test board and dropped 3 times in three
directions with shock applied for 0.01 seconds at 981 m/s2. The change in inductance, if any,
is measured after the tests.
Vibration Test
The change in inductance, if any, is measured after the following condition:
● A specimen coil/inductor is mounted on a test board of vibration instrument.
● Overall amplitude: 1.5mm, frequency range: 10~55Hz, and swept in the (10~55~10)Hz order
per minute for 2 hrs in each of the 3 directions for total of 6 hrs.
Humidity Test
The change in inductance, if any, is measured after exposure in a test chamber to humidity of 90% to
95% R.H. at 60±2°C for 500±12 hours and 1 hour exposure at room temperature.
