Product Description
Samsung Chip Resistors
Samsung Chip Resistors are manufactured in accordance with EU RoHS directive, ensuring the absence of restricted materials such as Cd, Pb, Hg, Cr6+, As, Br, and their compounds, as well as PCB and asbestos. Additionally, bromic materials (PBBs, PBBOs, PBDO, PBDE, PBB) and phthalate materials (DEHP, BBP, DBP, DIBP) are not used. The fabrication process also avoids Ozone Depleting Substances (ODS) like Freon, Haron, 1-1-1 TCE, CCl4, and HCFC. These resistors are designed for various applications including TV, Computer, and Mobile devices.

Key Technical Characteristics
| Characteristic | Description |
| Rated Voltage | DC or AC (rms) voltage that can be applied constantly. Calculated as E = sqrt(P*R). Limited by Max Working Voltage. |
| Max Working Voltage | Maximum voltage that can be applied, limited by size. |
| Critical Resistance Value | Resistance value at which rated voltage equals max working voltage. Above this value, max working voltage is applied, and power decreases. |
| Rated Power | Power load regulation for continuous use at 70. Applied power must be reduced above 70 according to the power derating curve. |
| Power Derating Curve | Illustrates reduction of rated power based on ambient temperature exceeding 70. |
| TCR (Temperature Coefficient of Resistance) | Change rate of R-value per 1C within the working temperature range, based on 20C. Measured using the formula (R2-R1)/R1 * 1/(t2-t1) * 10^6. |
| Insulation Resistance | Resistance between electrode and ceramic body (>1,000M). Measured with DC voltage for 1 minute. |
| Dielectric Withstanding Voltage | Resistance between electrode and insulation layer (>1,000M). Measured with DC voltage for 1 minute. |
| Measurement of Resistance Value | DC voltage applied at room temperature. Voltage varies by resistance range. 4-terminal instrument recommended for noise reduction. PCB must match reference for chip measurement. Standard values follow JIS C 5201-1 (4.5). |
