These all-welded units are characterized by their low temperature coefficients and resistance to thermal shock, making them ideal for a wide range of electrical and electronic applications. Units with 1% and 5% tolerances are identical in construction and electrical specifications. Durable but economical 40 Series resistors exceed industry requirements for quality. 50K = 50,000Ω S ta n d a r d pa rt n u m b e r s f o r 4 0 s e r i e s 45J––– 5 40J––– 10 43J––– 3 42J––– 2 41J––– 1 40F––– 10 45F––– 5 43F––– 3 41F––– 1 –––68R –––75R –––82R –––100 –––120 –––125 –––150 –––180 –––200 –––220 –––225 –––250 –––270 –––300 –––330 –––350 –––390 –––400 –––450 –––470 –––500 –––560 –––600 –––680 –––750 –––800 –––820 –––900 –––1K0 –––1K1 –––1K2 –––1K5 –––1K8 –––2K0 Ohmic value 40J––– 10 45J––– 5 43J––– 3 40J––– 10 82 100 120 125 150 180 200 220 225 250 270 300 330 350 390 400 450 470 500 560 600 680 750 800 820 900 1,000 1,100 1,200 1,500 1,800 2,000 42J––– 2 45J––– 5 68 75 41J––– 1 43J––– 3 40F––– 10 42J––– 2 45F––– 5 41J––– 1 43F––– 3 40F––– 10 41F––– 1 45F––– 5 Ohmic value 43F––– 3 2,200 –––2K2 2,500 –––2K5 2,700 –––2K7 3,000 –––3K0 3,300 –––3K3 3,500 –––3K5 3,900 –––3K9 4,000 –––4K0 4,500 –––4K5 4,700 –––4K7 5,000 –––5K0 6,000 –––6K0 6,800 –––6K8 7,000 –––7K0 7,500 –––7K5 8,000 –––8K0 9,000 –––9K0 10,000 –––10K 12,000 –––12K 13,000 –––13K 15,000 –––15K 17,000 –––17K 20,000 –––20K 22,000 –––22K 25,000 –––25K 30,000 –––30K 33,000 –––33K 35,000 –––35K 40,000 –––40K 50,000 –––50K = Standard values Part No. Prefix Suffix –––R10 –––R15 –––R20 –––R25 –––R30 –––R33 –––R40 –––R50 –––R75 –––1R0 –––1R5 –––2R0 –––2R2 –––3R0 –––4R0 –––5R0 –––7R5 –––10R –––12R –––15R –––18R –––20R –––22R –––25R –––27R –––30R –––33R –––35R –––39R –––40R –––47R –––50R –––56R –––62R Wattage and Tolerance 1% Tolerance 5% Tolerance Part No. Prefix Suffix 0.1 0.15 0.2 0.25 0.3 0.33 0.4 0.5 0.75 1 1.5 2 2.2 3 4 5 7.5 10 12 15 18 20 22 25 27 30 33 35 39 40 47 50 56 62 Part No. Prefix Suffix 41F––– 1 Wattage and Tolerance 1% Tolerance 5% Tolerance Ohmic value Wattage and Tolerance 1% Tolerance 5% Tolerance Shaded values involve very fine resistance wire and should not be used in critical applications without burn-in and/or thermal cycling. = Non-standard values subject to minimum handling charge per item Check product availability at www.ohmite.com Ohmite Mfg.
