ELECTRONICS, INC. 28_IL117.1004 is a hybrid mountable version with copper pedestal terminals and an aluminum surface layer for wire bonding. The back surface of these devices is metallized for solder attachment of the chip resistor to a heat sinking substrate. Specifications: Temperature Coefficient: TC referenced to +25°C, ∆R taken at +150°C. 0.050 ohm to 0.20 ohm, 0 to +100 ppm/°C. 0.010 ohm to 0.049 ohm, 0 to +200 ppm/°C. Inductance: Less than 5 nH typical. Load Life: 1000 hours at rated power, based upon 150°C max. chip temperature, ∆ R ± (0.5% + 0.0005 ohm). Momentary Overload: 1.5 times rated power, for 5 seconds, ∆R ± (0.5% + 0.0005 ohm). Operating Temperature: -55°C to +150°C. Measurement Note: All measurements are taken using Kelvin connections per the recommended connection locations. Ordering Information: Ko signifies tape thickness and dimension 12mm 0.473” Ao Bo 7” dia. (178 mm) .512” arbor hole (13mm) Packaging information: Style FC, flip chip resistors, are shipped with the bare ceramic side up in the pocket, with the solderable pedestals facing down. Style WB, wire bondable resistors, are shipped with the wire bondable pedestals facing up in the pocket. The illustration shows the orientation of the CD2015 chip resistors in the tape. The CD2520 chip resistors are rotated 90° from what is shown in the illustration. Style WB - Wire Bond Version Note 3: Thermal Resistance - In High Power Applications where the circuit board material provides high heat sinking benefits (such as IMS, Alumina, or other) the thermal resistance of the chip resistor is useful to establish the maximum power capability of the chip resistor in the application. The film temperature is measured at the center of the resistor element and the solder pad temperature is measured at the soldered interface with the circuit board. Maximum temperature of the chip resistor (at the center of chip) should not exceed 150°C through the temperature range of the application. WB Resistor mounting Circuit board: IMS, Ceramic (Alumina) , or other. Sense Wire Current Wire Film Temperature Measuring Point Solder pad, soldered interface with circuit board. Sense Wire Current Wire Location for Sense (Potential) Connection: General Information for Type CD - Style FC and Style WB - Chip Resistors Solder attachment notes: During soldering of the Type CD Resistor the soldering temperature profile must not cause the pedestal terminals of this device to exceed 220°C. Style FC - Flip Chip version resistors have a bare ceramic back surface. The recommended solder for flip chip solder attachment is 62Sn / 36Pb / 2Ag. Style WB - Wire Bond version resistors have a metallized back surface for soldering to a substrate or a heat sink. The recommended solder is 62Sn / 36Pb / 2Ag. Model Resistance Min. Max.
