a little history . . . sei electronics started manufacturing resistors in 1928, as part of the stackpole carbon company in st. marys pennsylvania. to this day, sei continues to focus on resistor products C and nothing else. in 1986, the senior managers of stackpoles resistor business bought the res istor operations from the stackpole corporation and established a separate company under the name stackpole electronics. following a short transitional period, the name of the company was changed to sei electronics, inc. to further establish a clearly independent identity. in 1989, sei strengthened its manufacturing base by becoming formally af filiated with akahane electronics in japan, which has (resistor) manufacturing plants in japan, taiwan and mainland china. today sei is one of the largest exclusive resistor supp liers in the world, with headquarters in raleigh, north carolina and a large distribu tion facility and cu stomer service center in el paso, texas. in addition, sei is in the process of building a solid global presence with a new d istribu tion cen ter in toronto (adding to our existing facility in singapore). seis products are used in virtually every segment of the electronics market C including compu ters and computer periphera ls, telecommunications, automotive, consumer electronics, industrial controls, medical e lectron ics, and measurement and testing equipment. the vast majority of these cu stomers purchase produ cts through seis network of national and regional electronics distributors. sei also sells directly to a select group of original equipment manufacturers (oems) and to a growing base of contract electronics manufacturers ( cems). field sales activities are managed by seis sales staff and supported by an experienced group of sales representatives throughout north america. great products, great quality sei specializes in fixed resistors, and because of our specialization, we are a ble to supply an extensive range of surface mount and axial-leaded resistor products. we have significant market share in all of the high demand fixed resistor products, including thick film chip, thick film chip arrays, carbon film, metal film, and metal oxide resistors. in add ition, sei is the only active supplier of carbon composition resistors remaining in north amer ica. we also take pride in our ability to support more specialized products, including our line of ultra-precision metal film resistors. our focus on resistors allows us to offer inventory and short lead-time programs on these unique products when others cannot (or are unwilling to do so). and in case youre wondering, we are iso 9002 certified and were in the process of pursuing qs 9000 registration. superior service we are proud of the fact that our distributors tell us that sei is the best, most service-oriented supplier in the industry. weve earned this reputation by listening to our customers needs, and then working very hard at every aspect of our business to address those needs. sei realizes that success rarely happens by accident, and for that reason, there are a number of well-d esigned programs behind every yes we say to customers. one example is our extensive inventory (over 2 billion resistors in stock) of the products that we know the market demands, supported by the shortest manufacturing lead-times in the ind ustry. we add to the effectiveness of our inventory by putting the systems and people in place to process and ship same day orders with ease. we realize that the market demands products off the shelf , and we deliver, every day. leading edge technology for our cu stomers and now sei is c hanging the way engin eers and buyers of resistors do business by providing the first truly functional web site in the ind ustry. we were not satisfied with a web site that simply told a marketing story; we wanted one that provided real business tools. as a result, our customers can now do stock checks 24 hours a day, can access purchase order details right down to who signed for the shipment, and can review shipment schedules to guarantee that the products on order are exactly what production needs. engineers can access product specifications fast, without having to click thr ough a maze of pages of unimportant data. this is how the web should work! check it out at www.seielect.com. when we look at the combination of everything we offer, we often refer to it as the resistorplus program because we supply resistors plus all the service and support needed to effectively manage the supply chain. give us a call today and see how we can make your life easier by servicing all of your resistor needs C no hassles, no problems. sei electron ics, your primary source for quality resistor products. rev. 07/98 sei electronics - company profile sei electronics inc . p.o. box 58789 raleigh, nc 27658-8789 telephone: (919) 850-9500 fax: (919) 850-9504 toll free: (888) sei-sei-sei www.seielect.com email: marketing@seielect.com iso 9002 registered

performance curves 1. color bands. the resistors are permanently color banded for resistance value and tolerance in accordance with eia specifications. 2. helixing. the units are helixed to a predetermined base to final value ratio to obtain the best tcr, noise and stability characteristics. 3. film. carbon-film resistors have a homogeneous film of pure carbon deposited by a pyrolitic process at carefully controlled temperatures. 4. substrates. the su bstrates are of a pro prieta ry no na lka line ceramic, prepared and processed under exacting conditions to guarantee the utmost in uniformity and surface characte ristics. 5. insulation. the res istors are coated with multiple layers of a baked-on fire-retardant synthetic resin which provides the units with a high degree of mechanical and electrical protection in the most adverse operating conditions. 6. terminations. positive contact is provided to the resistant element by precision-made end caps. the lead wires are attached by using proprietary welding te chniques. page d-3 carbon film resistors performance curves/construction note: typical t/c for 11-22m is -2,800 ppm/c. temperature coefficient (typical) derating curve (typical) current noise (typical) construction surface temperature rise vs. load rev. 07/98 sei electronics inc . p.o. box 58789 raleigh, nc 27658-8789 telephone: (919) 850-9500 fax: (919) 850-9504 toll free: (888) sei-sei-sei www.seielect.com email: marketing@seielect.com iso 9002 registered
