For long run machine assembly placement of a component costs 3-4 cents. A resistor and an array cost sub cent. So one network saves about 10 cents. It may become difference of tens of thousands of dollars for serial production.

2018年11月26日 · Two advantages resistor networks offer over discrete resistors in analog applications are better thermal tracking and availability of precision ratios. Because the resistance network elements share a common substrate, they are subject to more equal thermal effects. Networks are available in precision ratios.

2013年7月23日 · Typical advantages of using resistor networks: Smaller part count, as mentioned. Therefore faster assembly. Better matching of individual resistor values and drift, by being in the same package. Saving board space: Not always, but when you account for the keepout area for individual parts, it's an even bet.

Summary of convex resistor array advantages from the EEVBlog article: 5-sided vs. 3 sided termination gives better solderability; A larger gap between terminations reduces solder bridging; Better view for visual inspection; Larger terminations increase reflow soldering self-alignment; Better part availability (70% of the market) Lower cost in ...

2011年6月14日 · SMT resistor arrays are available in convex or concave form. What are the dis/advantages of either?

However, this does not modelize the relative variations of resistor values within the array. Each individual resistor has a "random" value that is dependant on other resistor's value. After thinking about it twice, it would be like having correlated random variables. But I like your idea of having a "monte-carlo'ed" parameter.

2017年8月19日 · I need 4 accurately matched resistors for my circuit, I heard resistor arrays have better matching quality. but I don't know what parameter to look for in the datasheets. all I see is Tolerance. I ...

In the case of a resistor array, 1206 describes the size of the package, and does not imply a pin configuration. 1206 sized single resistors have been around a lot longer that the arrays, so I would assume that the 1206 footprint is for a single resistor. Not an error, per se, but a case where a single resistor in a 1206 package is assumed.

2022年10月1日 · It's a type of precision array consisting of a resistive material patterned on a ceramic substrate, then laser-trimmed to the right resistances (or resistance ratios, if that matters more). They're commonly used in lab equipment like multimeters or oscilloscopes, and if you go looking for precision resistor arrays you'll likely find ones that ...

2011年6月24日 · At Vishay I found these "High Precision Thin Film Chip Resistor Arrays": The networks provide 1 ppm/°C TCR tracking, a ratio tolerance as tight as 0.01 % and outstanding stability. edit Linear Technology has the LT5400 resistor array with the following specs: 0.01% Matching 0.2ppm/°C Matching Temperature Drift
