The PMA has been designed for flip-chip mounting on the pc-board. All standard soldering processes like reflow-, infrared-, vapor phase-, dip- and wave-soldering can be used. The heat which is generated by the measuring current is conducted very efficiently to the pc-board via the heat conductive substrate and the solder joints. pad size (bottom view) Precision Resistor Type PMA -40 -20 20 40 60 80 100 120 T [oC] -0.4 -0.2 0.2 DR/R20 [%] Technical data resistance range 2mOhm - 500mOhm tolerances 1%, 5% temperature coefficient tcr ( R > 20mOhm ) < ±30ppm/K ( 20°C to 60°C ) applicable temperature range -55°C to +125°C load capacity 3W thermal resistance to ambiente Rth < 10K/W dielectric withstanding voltage 100VAC inductance < 10nH stability deviation <0.5% after 2,000h 0 20 40 60 80 100 120 140 terminal temperature TK / [oC] 0.25 0.5 0.75 P / P Nom stability: 1% stability: 0.5% reduced
