| General Purpose Failsafe Molded Wirewound Resistor SPH/SPF Series * * * * * * * * SPF is fusible 5%, 10% tolerance 0.1 ohm to 2400 ohms Weldable and solderable leads 2 watt rated with 1 watt dimensions Drop-in replacement for BWH/BWF Lead free, RoHS compliant construction available TCR's as low as 150 ppm/C standard (custom TC's available) 3 1 4 2 (See notes below) Electrical Data IRC Type SPH SPF 1. Resistive Element All resistor types have resistance alloy winding on a braided fiberglass substrate. Intermediate silicone coatings are used to enhance processibility and to provide protection to the resistive element. 2. Termination The SPH and SPF resistors are terminated using an alloy coated copper flashed steel lead welded to a cap of the same material. This termination assembly is mechanically crimped, utilizing an improved crimp design, to the resistive element. 3. Encapsulation The SPH and the SPF are encapsulated utilizing a compression molded phenolic plastic material. The SPF has a flame resistance coating applied over the resistive element to provide flammability protection when destructive overloads may occur. 4. Marking All products are marked utilizing heat and solvent resistant color code bands consistent with EIA/MIL requirements. The first band is double width to designate wirewound construction. A fifth band, blue in color, is used for flameproof identification. EIA RS-344 Style MIL-R-11 Style Resistance - Std. Tolerance - Std. Power Rating Max. Continuous Working Voltage Min.
