TCT 0603, TCU 0805, TCA 1206 Vishay Beyschlag Trimmable Flat Chip Resistors FEATURES * * * * * * * TCT 0603, TCU 0805 and TCA 1206 trimmable flat chip resistors are best suited whenever stable circuit adjustment is required and potentiometers will be either too expensive, too unstable or too large. The trimming is done directly on the printed-circuit board (PCB) using a state of the art laser trimming system e.g. with YAG or CO2 laser source. Typical applications include any type of electronic sensors, oscillators or electronic circuits which have to be trimmed to certain functional parameters after PCB assembly.

However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. www.vishay.com 178 For technical questions, contact: thinfilmchip@vishay.com Document Number: 28711 Revision: 23-Nov-09 TCT 0603, TCU 0805, TCA 1206 Trimmable Flat Chip Resistors Vishay Beyschlag PART NUMBER AND PRODUCT DESCRIPTION (1) PART NUMBER: TCT06030C4702XP500 T MODEL/SIZE TCT0603 TCU0805 TCA1206 C T 0 6 SPECIAL CHARACTER 0 = Neutral 0 3 0 TCR C = 50 ppm/K B = 100 ppm/K C 4 7 0 VALUE 3 digit value 1 digit multiplier MULTIPLIER 9 = *10-1 0 = *100 1 = *101 2 = *102 3 = *103 4 = *104 5 = *105 2 X TOLERANCE W = + 0/- 30 % X = + 0/- 20 % Y = + 0/- 10 % P 5 0 PACKAGING P5 PW 0 SPECIAL Up to 2 digits 00 = Standard PRODUCT DESCRIPTION: TCT 0603 - 50 - 20 % P5 47K TCT 0603 - 50 - 20 % P5 47K MODEL TCT TCU TCA SIZE 0603 0805 1206 TCR (2) 50 ppm/K 100 ppm/K TOLERANCE - 10 % = + 0/- 10 % - 20 % = + 0/- 20 % - 30 % = + 0/- 30 % PACKAGING P5 PW RESISTANCE VALUE 47K = 47 k 1M = 1 M Notes (1) Products can be ordered using either the PRODUCT DESCRIPTION or the PART NUMBER (2) A temperature coefficient 100 ppm/K is marked -00 TEMPERATURE COEFFICIENT AND RESISTANCE RANGE RESISTANCE VALUE (3) DESCRIPTION TCR 100 ppm/K 50 ppm/K TOLERANCE TCT 0603 TCU 0805 TCA 1206 + 0/- 30 % 10 to 1 M 10 to 1 M - + 0/- 20 % 10 to 1 M 10 to 1 M + 0/- 10 % 10 to 1 M 10 to 1 M - + 0/- 30 % 100 to 1 M 100 to 1 M - + 0/- 20 % 100 to 1 M 100 to 1 M - + 0/- 10 % 100 to 1 M 100 to 1 M - 10 to 1 M Note (3) Resistance values to be selected from E12 (preferred) or E24 series Resistance ranges printed in bold are preferred TCR/tolerance combinations with optimized availability.

Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly. Specified power rating above 125 C requires dedicated heat-sink pads, which depend on board materials. The given solder pad dimensions reflect the considerations for board design and assembly as outlined e.g. in standards IEC 61188-5-x, or in publication IPC-7351. They do not guarantee any supposed thermal properties, particularly as these are also strongly influenced by many other parameters. Still, the given solder pad dimensions will be found adequate for most general applications, e.g. those referring to "standard operation mode". Please note however that applications for "power operation mode" require special considerations for the design of solder pads and adjacent conductor areas. www.vishay.com 180 For technical questions, contact: thinfilmchip@vishay.com Document Number: 28711 Revision: 23-Nov-09 TCT 0603, TCU 0805, TCA 1206 Trimmable Flat Chip Resistors DESCRIPTION Production is strictly controlled and follows an extensive set of instructions established for reproducibility. A newly developed cermet layer is deposited onto a high-grade (Al2O3) ceramic substrate and conditioned to achieve the desired temperature coefficient. Pre-contacts are built on both sides of the substrate. The resistor elements are covered by glass for superior electrical, mechanical and climatic protection. The terminations receive a final pure tin-on-nickel plating. The result of the determined production is verified by an extensive testing procedure performed on 100 % of the individual chip resistors. Only accepted products are laid directly into the paper tape in accordance with IEC 60286-3 (3). Vishay Beyschlag The resistors are RoHS compliant; the pure tin plating provides compatibility with lead (Pb)-free and lead-containing soldering processes. Solderability is specified for 2 years after production or requalification. The permitted storage time is 20 years. The immunity of the plating against tin whisker growth has been proven under extensive testing. All products comply with the GADSL (1) and the CEFIC-EECA-EICTA (2) list of legal restrictions on hazardous substances. This includes full compliance with the following directives: * 2000/53/EC End of Vehicle life Directive (ELV) and Annex II (ELV II) * 2002/95/EC Restriction of Substances directive (RoHS) the use of Hazardous * 2002/96/EC Waste Electrical and Electronic Equipment Directive (WEEE) ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using wave, reflow or vapour phase as shown in IEC 61760-1 (3). The encapsulation is resistant to all cleaning solvents commonly used in the electronics industry, including alcohols, esters and aqueous solutions. The suitability of conformal coatings, if applied, shall be qualified by appropriate means to ensure the long-term stability of the whole system. APPROVALS The resistors are tested in accordance with EN 140401-802 which refers to EN 60115-1 and EN 140400. The detail specification refers to the climatic category 55/125/56, which relates to the "Standard operation mode" of this datasheet.
