type mpt series the mpt resistor series are a range of t0220 packaged, low inductance thick film power resistors which complement the thin film mpr series. this small size, high power device packaged in 5 case sizes are ideally suited to applications where high power dissipation yet small size are key design requirements. the mpt resistor series are the ideal solution for small snubber circuits, the output side of high speed pulse generators and low inductive resistor requirements in switch mode power supplies. key features small size to220 package easy to mount isolated moulded case non inductive high power up to 100w with suitable heatsink characteristics - environmental characteristic test method short time overload: r 0.3% 2 times rated power with applied voltage not to exceed 1.5 times maximum continuous operating voltage for 5 seconds mpt100 - r 0.5% 1.5 times rated power and v(dc) =<1.5vmax for 5 seconds load life: r 1.0% mil-prf-39009d, 2000 hours at rated power moisture resistance: r 0.5% mil-std-202f, method 103b mpt100 - r 0.5% -10c~+65c, rh>90%, cycle 240 hours thermal shock: r 0.3% mil-std-202f, method 107g mpt100 - r 0.5% terminal strength: r 0.2% mil-std-202f, method 211, cond. a (pull test) 2.4n vibration, high frequency: r 0.2% mil-std-202f, method 204, cond. d mpt100 - r 0.4% characteristics - electrical mpt20 mpt30 mpt35 mpt50 mpt100 resistance range: r10 - 10k r10 - 10k r10 - 10k r10 - 10k r10 - 10k selection series: e24 rated power with suitable heatsink: 20w 30w 35w 50w 100w rated power without heatsink: 3w 2.25w 2.5w 3w 3.5w maximum operating voltage: 350v dielectric strength: 1800vac insulation resistance: 10g min. operating temperature range: -65c to +150c -65c to +175c tcr / tolerance value chart mpt 20 / 30 / 35 / 50 mpt100 resistance range / tolerance 1% / 5% / 10% 0.5% 1% / 5% / 10% r10 - 2r7 300ppm - 300ppm 3r - 10r 100ppm - 100ppm 3r - 10r 200ppm - 200ppm 11r - 10k 50ppm 50ppm 50ppm 11r - 10k 100ppm 100ppm 100ppm 11r - 10k 200ppm 200ppm 200ppm case temperature to be used for definition of applied power limit case temperature measurement must be made with a thermocouple contacting centre of component mounted on designed heatsink thermal grease should be correctly applied power derating curve 0 25 50 75 100 125 150 175 case temp.
