The maximum temperature rise for 10A and 15A fuses shall be +85C. Resistance: See table I. Overload interrupt:
7、Percentage of nominal rating, interrupt time -55C through +125C, 200 percent in 0 second to 5 seconds; 300 percent in 0 second to 0.1 second. Interrupt time for 15A fuses shall be 10 seconds maximum at 200 percent of rated current and .3 second maximum at 300 percent of rated current. Short circuit
8、interrupt: 300 amperes at maximum voltage dc. Shock: Method I of MIL-PRF-23419. Thermal shock: Method 107, MIL-STD-202, test condition B. Qualification: Qualification may be granted to style FM08 fuses to those qualified for style FM04 fuses, provided they meet the verification requirements shown be

Nonconforming units shall be
10、 removed from the lot. a. Seal - Immerse in a clear mineral oil bath at +125 C for 1 minute. No bubbles shall be detected. (See method 112, MIL-STD-202, test condition A.) b. Voltage drop - See table I. c. Resistance - See table I. d. Visual and mechanical - Inspection shall be by 3X minimum magnifi
11、cation. Extent of qualification: Qualification may be extended to style FM04 fuses to those qualified for style FM08 fuses. Solderability: Fuses shall be tested in accordance with MIL-PRF-23419. Gold plated leads shall have the gold removed by single or double dipping into a flowing or nonflowing ho
12、t solder of sufficient volume to assure complete gold removal. Resistance to soldering heat: Fuses shall be tested in accordance with MIL-PRF-23419. Marking: Fuses shall be marked with the manufacturers name or trademark and current rating only. Part or Identifying Number (PIN): The PIN is derived f
