type rp73 series smd precision resistors components electronic meggitt meggitt holsworthy key features the rp73 series is a stable thin film chip resistor range offering various power dissipation relating to chip size. the resistor is produced with three print layers for longer life and better performance. values are restricted to e96 grids and the rp73 has accurate and uniform physical dimensions to reduce placement problems. the range is constantly being extended. due to special technology used to produce tight tolerance, low tcr at high values the rp73 is not individually part marked. high precision - tcr 10 ppm/c tcr 10ppm/c wider resistor value options supplied on reels of 1000/4000 or 5000 tolerances down to 0.05% thin film (nichrome) stable high frequency performance 200v dc operating voltage temperature -55c to +155c electronic assemblies precision resistors smd precision resistors precision networks meggitt holsworthy sales action desk fax: (01793 611777) tel: (01793 611666) email: sales@megelec.co.uk web site: www.megelec.co.uk log no f0763 issue 8 2 pages 06-01
