Above 7A uses 70 micron thickness copper layer test board of IEC 60127-3. Others uses 35 micron thickness copper layer. Typical Voltage Drop (Measured at rated current after temperature stabilizes) 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. 0310 BU-SB10214 Page 1 of 2 Data Sheet 4321Time-Current Curves Current In Amps Packaging Packaging Code Prefix Description TR 2500 fuses on 12mm tape-and-reel on a 180mm reel per EIA-481-A & IEC286-3 The only controlled copy of this Data Sheet is the electronic read-only version located on the Cooper Bussmann Network Drive.
