(2) Rated voltage: PxR (3) The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature of 155 C is not exceeded. www.vishay.com 174 For technical questions, contact: filmresistors.thickfilmchip@vishay.com Document Number: 20012 Revision: 13-Oct-08 D../CRCW....-TR Lead (Pb)-bearing Thick Film, Rectangular, Trimmable Chip Resistors Vishay PART NUMBER AND PRODUCT DESCRIPTION PART NUMBER: CRCW080525R0KKTATR (1) C R C W 0 8 0 5 2 5 R 0 K K T A T R MODEL VALUE TOLERANCE TCR PACKAGING (2) SPECIAL CRCW0402 CRCW0603 CRCW0805 CRCW1206 CRCW1210 CRCW2010 CRCW2512 R = Decimal K = Thousand M = Million K = 10 % L = 15 % M = 20 % U = + 0 %/- 10 % V = + 0 %/- 20 % W = + 0 %/- 30 % K = 100 ppm/K N = 200 ppm/K TA, TB, TC, TD, TE, TF, TG, TH, TI, TL up to 2 digits TR = Customer Trimmable PRODUCT DESCRIPTION: CRCW0805-TR 250 K 100 RT1 CRCW0805-TR 250 K 100 RT1 MODEL RESISTANCE VALUE TOLERANCE TCR PACKAGING (2) CRCW0402-TR CRCW0603-TR CRCW0805-TR CRCW1206-TR CRCW1210-TR CRCW2010-TR CRCW2512-TR 250 = 25R 392 = 3K9 105 = 1M0 K = 10 % L = 15 % M = 20 % U = + 0 %/- 10 % V = + 0 %/- 20 % W = + 0 %/- 30 % 100 ppm/K 200 ppm/K RT1, RT5, RT6, RT7, RF4, R02, R67, R82, RG1, R20 Notes (1) Preferred (2) Please way for ordering products is by use of the PART NUMBER refer to table PACKAGING, see below PACKAGING REEL MODEL PACKING CODE TAPE WIDTH DIAMETER PITCH PIECES/REEL PART NUMBER PAPER D10/CRCW0402-TR D11/CRCW0603-TR D12/CRCW0805-TR D25/CRCW1206TR 8 mm 8 mm 8 mm 12 mm CRCW2010TR 12 mm Document Number: 20012 Revision: 13-Oct-08 12 mm PRODUCT DESC.
