The rated dissipation applies only if the permitted film temperature is not exceeded. 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. • These resistors do not feature a limited lifetime when operated within the permissible limits. 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 276 For technical questions, contact: [email protected] Document Number: 28770 Revision: 11-Sep-08 ACAS 0612 AT - Precision Automotive Automotive Precision Thin Film Chip Resistor Array Vishay Beyschlag PART NUMBER AND PRODUCT DESCRIPTION (1) PART NUMBER: ACASA1100A2200P5AT A C A S A 1 1 0 RESISTANCE VALUE (2) (3) MODEL TERMINAL SIZE ACA S = Convex square A = 0612 0 A 2 ACCURACY GRADE (4) 2 0 0 RESISTANCE VALUE (2) (3) 3 digit TCR, Tracking, resistance Tolerance and value R1, R4 Matching 1 digit multiplier A, B, E, F MULTIPLIER J, K, N or P 9 = *10-1 0 = *100 1 = *101 2 = *102 3 = *103 P 5 A T PACKAGING (5) SPECIAL P1 P5 AT = Automotive 3 digit resistance value R2, R3 1 digit multiplier MULTIPLIER 9 = *10-1 0 = *100 1 = *101 2 = *102 3 = *103 PRODUCT DESCRIPTION: ACAS 0612 110R A 220R AT P5 ACA S 0612 110R A 220R AT P5 MODEL TERMINATION SIZE RESISTANCE VALUE R1, R4 (2) (3) ACCURACY GRADE (4) RESISTANCE VALUE R2, R3 (2) (3) SPECIAL PACKAGING (5) ACA = Chip Array S = Convex 0612 110R = 110 Ω 1K1 = 1.1 kΩ 22K1 = 22.1 kΩ TCR, Tracking, Tolerance and Matching A, B, E, F J, K, N or P 220R = 220 Ω 1K1 = 1.1 kΩ 22K1 = 22.1 kΩ AT = Automotive P1 P5 Notes (1) Products can be ordered using either the PART NUMBER or the PRODUCT DESCRIPTION (2) R = R ≤ R = R ; please refer to APPLICATION INFORMATION, see below 1 4 2 3 (3) Different resistance values are available on request (4) Please refer to table TEMPERATURE COEFFICIENT AND RESISTANCE RANGE, see below (5) Please refer to table PACKAGING, see below PACKAGING MODEL ACAS 0612 AT PACKAGING CODE TAPE WIDTH DIAMETER PIECES PITCH 8 mm 180 mm/7" 1000 4 mm P1 8 mm 180 mm/7" 5000 4 mm P5 PAPER TAPE DIMENSIONS ACAS 0612 AT in millimeters A T2 T1 H A1 A DIMENSIONS - chip resistor array, mass and relevant physical dimensions TYPE ACAS 0612 AT W (mm) L (mm) H (mm) P (mm) A1 (mm) A (mm) T1 (mm) T2 (mm) MASS (mg) 1.5 ± 0.15 3.2 ± 0.15 0.45 ± 0.1 0.8 ± 0.1 0.6 ± 0.15 0.4 ± 0.15 0.3 ± 0.15 0.4 ± 0.15 6.77 Document Number: 28770 Revision: 11-Sep-08 For technical questions, contact: [email protected] www.vishay.com 277 ACAS 0612 AT - Precision Automotive Vishay Beyschlag Automotive Precision Thin Film Chip Resistor Array PATTERN STYLES FOR CHIP RESISTOR ARRAYS U I X Y G Dimensions in mm P Z 0.1 limits for solder resistance RECOMMENDED SOLDER PAD DIMENSIONS FOR CHIP RESISTOR ARRAYS TYPE ACAS 0612 AT G (mm) Y (mm) X (mm) U (mm) Z (mm) I (mm) P (mm) 0.8 1.15 0.64 0.44 3.1 0.36 0.8 TEMPERATURE COEFFICIENT AND RESISTANCE RANGE DESCRIPTION ACCURACY GRADE ABSOLUTE TCR RESISTANCE VALUE TCR TRACKING (1) ABSOLUTE TOLERANCE TOLERANCE MATCHING (1) ACAS 0612 AT A ± 25 ppm/K 10 ppm/K ± 0.25 % 0.1 % 47 Ω to 150 kΩ B ± 25 ppm/K 10 ppm/K ± 0.5 % 0.25 % 47 Ω to 150 kΩ 47 Ω to 150 kΩ E ± 25 ppm/K 15 ppm/K ± 0.25 % 0.1 % F ± 25 ppm/K 15 ppm/K ± 0.5 % 0.25 % 47 Ω to 150 kΩ J ± 25 ppm/K 25 ppm/K ± 0.25 % 0.1 % 47 Ω to 150 kΩ K ± 25 ppm/K 25 ppm/K ± 0.5 % 0.25 % 47 Ω to 150 kΩ N ± 50 ppm/K 25 ppm/K ± 0.5 % 0.5 % 47 Ω to 150 kΩ P ± 50 ppm/K 50 ppm/K ± 0.5 % 0.5 % 47 Ω to 150 kΩ Note (1) In applications with defined resistance ratios like voltage dividers or feedback circuits, an array with a defined tracking of e.g. 10 ppm/K is required to replace discrete resistors with a temperature coefficient of ± 5 ppm/K. Furthermore, in order to achieve the same tolerance of ± 0.05 % of individual resistors, an array requires a matching of 0.1 %. The result of the determined production is verified by an extensive testing procedure and optical inspection performed on 100 % of the individual chip resistors. Only accepted products are laid directly into the paper tape in accordance with IEC 60286-3*. APPLICATION INFORMATION R1 R2 R3 R4 Circuit Type 03 DESCRIPTION The production of the components is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous film of metal alloy is deposited on a high grade (96 % Al2O3) ceramic substrate and conditioned to achieve the desired temperature coefficient. Specially designed inner contacts are realised on both sides. A special laser is used to achieve the target value by smoothly cutting a meander groove in the resistive layer without damaging the ceramics. The resistor elements are covered by a protective coating designed for electrical, mechanical and climatic protection. The terminations receive a final pure tin on nickel plating. www.vishay.com 278 ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using reflow or vapour phase as shown in IEC 61760-1*. 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. The resistors are RoHS compliant; the pure tin plating provides compatibility with lead (Pb)-free and lead-containing soldering processes. The permitted storage time is 20 years, whereas the solderability is specified for 2 years after production or requalification. The immunity of the plating against tin whisker growth has been proven under extensive testing.
