Ideal for use in oil, gas, mine, chemical, pharmaceutical and process industries, the 308 Series surface mountable fuse was designed to limit the energy and temperature generated during its operation. The fuse design and its encapsulant are suitable for use in intrinsically safe apparatus and associated apparatus for peak voltage not exceeding 30V. Features • Surface Mountable • Encapsulated and sealed (0.7mm minimum) • Designed for operation in a range of hazardous area applications requiring 30V peak • RoHS compliant and Pb-Free • Fully compatible with lead-free solder alloys and higher temperature profiles associated with lead-free assembly • Global hazardous locaiton (haz loc) certificaitons Applications • Testing, measuring or processing electronic and electrical equipment • Motor controllers • Communication handsets/ two-way radios • Process control and automation • Sensors • Lighting • Flow/gas meters Electrical Characteristics for Series % of Ampere Rating 100% 250%* 350%** * Applicable to 750mA - 1.5A ** Applicable to 250mA - 1.5A Opening Time 4 Hours, Minimum 120 Seconds, Maximum 60 Seconds, Maximum Electrical Specifications by Items Catalog Number Ampere Rating (A) Amp Code Interrupting Rating Nominal Melting I2t (A2 Sec.)

The fuse must be mounted so that creepage and clearance distances aren’t impaired in any way. 2. The fuse is suitable for use in intrinsically safe equipment and associated apparatus for voltage not exceeding 30V peak. 3. Maximum surface temperature rise at 170% rated current: 250-375mA = 23°C, 500mA = 35°C, 750mA = 53°C, 1A = 38°C, 1.25-1.50A = 96°C. 4. Minimum Cold Resistance at -30°C is available upon request.

Re-rating depicted in this curve is in addition to the standard re-rating of 20% for continuous operation. Example: For continuous operation at 55°C, the fuse should be rerated as follows: I = (0.80)(0.90)IRAT = (0.72)IRAT 2. The temperature rerating curve represents the nominal conditions.
