Agency Information
• UL Recognition Guide JDYX2 & File E19180.
• CSA Component Acceptance: 053787 C 000 &
•
Environmental Data
• Thermal Shock: MIL-STD-202, Method 107,
• Vibration: MIL-STD-202, Method 204,
• Moisture Resistance: MIL-STD-202, Method 106,
• Solderability: ANSI/J-STD-002, Test B
* AC Interrupting Rating (Measured at rated voltage with a unity power factor); DC Interrupting Rating (Measured at rated voltage, time constant of less than 50 microseconds, battery source)
** DC Cold Resistance (Measured at 10% of rated current)
† Typical Melting I
‡ Typical Voltage Drop (Measured at rated current after temperature stabilizes)
It is recommended that fuses be mounted with ceramic (white) side facing up.
Device designed to carry rated current for four hours minimum. An operating current of 80% or less of rated current is recommended, with further derating required at elevated ambient temperatures.
