handling recommendations when flow soldering - the land width must be smaller than the chip resistor width to properly control the solder application. generally, the land width can be chip resistor width (w) x 0.7 to 0.8. when reflow soldering - solder application amount can be adjusted. thus the land width can be set to w x 1.0 to 1.3. rp73 c 2a 1k0 b tn common part a - 5ppm/c c - 10ppm/c d - 15ppm/c f - 25ppm/c g - 50ppm/c temp. coefficient package size rp73 - smd precision high power, high temperature 1j - 0603 2a - 0805 2b - 1206 2h - 2010 3a - 2512 resistor value a - 0.05% b - 0.1% d - 0.5% f - 1% tolerance packaging 100r (100 ohms) 1k0 (1000 ohms) 10k (10,000 ohms) 100k (100,000 ohms) 1m0 (1,000,000 ohms) tg - cut tape (250 pcs) tdf - reel (1000 pcs) td - reel (5000 pcs) how to order dimensions part number l 0.2 w 0.2 c d+0.2/-0.1 t 0.1 rp73 1j 1.6 0.8 0.3 +/- 0.2 0.3 0.4 rp73 2a 2.0 1.25 0.4 +/- 0.2 0.3 0.5 rp73 2b 3.2 1.6 0.5 +/- 0.2 0.4 0.6 rp73 2h 4.9 2.4 0.6 +/- 0.2 0.5 0.6 rp73 3a 6.3 3.1 0.6 +/- 0.2 0.5 0.6 solderability - 235c 2 seconds din iec 68t2 - 20 ta meth. 1 max soldering temperature - 260c 10 seconds din iec 68 t2 - 20, tb meth. 1a l d w t c literature no. 1773272 issued: 12-07 dimensions are shown for reference purposes only. dimensions are in millimetres unless otherwise specified. specifications subject to change. tycoelectronics.com passives.tycoelectronics.com smd high power precision resistors type rp73 series
