Surface mount capacitor code chart pdf12/28/2022 ![]() To assist in identification, this is sometimes entered in the tables as x (lower case) as in '4Px' - device code 4P with a date code. Colour, if significant, is shown in smallĪn ' L' or ' W' suffix usually indicates a low-profileĪ separate letter number group, often smaller and/or in a different orientation, is often used as a date code. Some devices have a single coloured letter (usually Other words these lower case prefixes or suffixes are ignored for indexing purposes, You'll find both of these in the '6' page though - in Position of the 'p' is important! In this case, p6A is a jfet, and 6Ap a bipolar Note that p6A (for example) is different from 6Ap. For example GD1 is the same as D1 which is a BCW31. With G have direct equivalents found in the rest of the code. Many devices from Rohm Semiconductors which start This smaller letter is merely a month of manufacture code. Letter after the device code, such as SA C. Many recent Motorola devices have a small superscript Philips/NXP have used -, t, p and w to An example, if you have a device with the code 1At, look up 1Ap. To save table space, often only ONE variant from each manufacturer will appear in the table. Note that these prefix/suffix letters are always shown in lower case. Siemensĭevices usually have a lower case ' s'. The second in Malaysia they appear in the codebook classified under ZS. For example 'Z-S' and 'ZtS ' are both 2PC4081Q devices made by Philips the first made in Hong Kong and Or lower case letter to indicate the country of manufacture. If the device is from Philips/NXP it will sometimes haveĪ lower case ' p' or sometimes ' t' added to the code some manufacturers have used a symbol Own identification code, or to show the country of manufacture. Many manufacturers use an extra letter as their Such that the ID code is the right way up. Some packages have nothing at all - in that case the device is shown The correct orientations, on others, one or more 'pins' may be a different size When you have looked up a device, the Base letter Of more detailed information if you require it. The entries under the Manufacturer column are not intended to beĬomprehensive rather they are intended to provide help on locating sources This compilation has been collected from manufacturers'ĭata and other sources of SMD device ID codes, pinout and leaded device equivalent May help and the codebook has some information about these. Identifying the package is not always easy - measuring the package dimensions Use the package style to differentiate between devices with the same ID code. May use the same code for different devices! If there is more than one entry, For example a deviceĬoded 1A might be either a BC846A or a FMMT3904. Unfortunately, each device code is not necessarily unique. On the first character shown in the left-hand frame. Now look up theĬode in the alphanumeric listing which forms the main part of this book by clicking The package style and note the ID code printed on the device. To identify a particular SMD device, first identify Of them will be as up to date as the original. Some are translations with my permission, some are just straight rip-offs. There are a number of other copies of this codebook on the Net, of varying ages. It's only here you'll get the most up-to-date information as it's updated often. The home of GM4PMK's SMD codebook is here - and Some ICs have been included, usually these areģ/4 pin devices or RF circuits I'm interested in. ![]() Is some information about ICs - but first and foremost the codebook is Sometimes I'm asked to put IC information in the codebook. Together with type numbers, device characteristics or equivalents and pinout It lists over 3,500 device codes in alphabetical order, This HTML book is designed to provide an easy means Identifying the manufacturers' type number of an SMDĭevice from the package code can be a difficult task, involving combing through Instead, a somewhat arbitraryĬoding system has grown up, where the device package carries a simple two- or To carry conventional semiconductor type numbers. SMD devices are, by their very nature, too small SMD Codebook Intro The Surface Mount Device
