RELIABILITY TEST
\t
STORAGE TEMPERATURE:
\t
-40℃~85℃
\t
OPERATING TEMPERATURE RANGE :
\t
-40℃~+125℃(CONTAIN HEATING COIL)
\t
EXTERNAL APPEARANCE :
\t
NO EXTERNAL DEFECTS CAN BE FOUND IN THE VISUAL INSPECTION.
\t
TERMINAL STRENGTH:
\t
FIXED INDUCTORS,ONE END OF THE ELECTRODE WITH 0.45KG PULLING FORCE,GUIDED THE NEEDLE DOES NOT FALL OFF.
\t
INSULATING RESISTANCE:
\t
THE INSULATION RESISTANCE SHOULD BE OVER 1000MΩ WHEN D.C.100V IS APPLIED TO THE WINDING –CORE. MEANWHILE NO STRUCTURE AND ELECTRIC DEFECTS SHOULD BE FOUND FOR 1 MINUTE.
\t
HUMIDITY TEST :
\t
INDUCTANCE DEVIATION IS WITHIN ±10.0% AND NO STRUCTURE AND ELECTRIC DEFECTS CAN BE FOUND AFTER 96±2hours TEST UNDER THE CONDITIONOF RELATIVE HUMIDITY OF 90~95% AND TEMPERATURE OF 40±5℃. AND 1 HOUR STORAGE UNDER ROOM AMBIENT CONDITIONS AFTER THE DEVICE IS WIPED WITH DRY CLOTH. 
\t
VIBRATION TEST :
\t
INDUCTANCE DEVIATION IS WITHIN ±10.0% AFTER 1 HOUR SWEEPING VIBRATION IN EACH THREE DIRECTIONS. NAMELY, FREQUENCY IS10~55Hz ANDTHE AMPLITUDE OF 1MINUTE CYCLE IS 1.5mm .
