Product Overview and Core Parameters
CRH2512J160RE04Z belongs to the CRH series high-power thick film surface mount resistors under Ever Ohms technology. This series of resistors is designed specifically for medium to high power circuits, using thick film technology and ceramic substrate structure, with high power density and excellent heat dissipation performance. The model code of CRH2512J160RE04Z clearly defines its key specifications:
CRH: Represents the high-power thick film resistor series of Tian'er Technology.
2512: The package size is imperial 2512, corresponding to metric 6.35mm × 3.2mm × 0.55mm, which belongs to the specification with higher power density in surface mount resistors.
J: The accuracy level is ± 5%, meeting the requirements of most industrial grade applications.
160R: The nominal resistance value is 160 Ω, covering the commonly used resistance range for power management, current detection, and other scenarios.
E04: Temperature coefficient and packaging code. The temperature coefficient (TCR) should be controlled within ± 100ppm/℃ to ensure that the resistance drift does not exceed 1.25% within a wide temperature range of -55 ℃ to+155 ℃.
The core electrical parameters of CRH2512J160RE04Z are as follows:
Rated power: 2W (continuous stable operation at 70 ℃ ambient temperature), with a short-term overload capacity of 2.5 times the rated power (5W), effectively responding to surge current surges during circuit startup.
Working voltage: The maximum working voltage is 200V, and the overload voltage can reach 400V, with good surge voltage tolerance.
Temperature coefficient: ± 100ppm/℃, ensuring stability in extreme temperature environments.
Environmental standards: Compliant with RoHS environmental requirements, lead-free and halogen-free, meeting EU and domestic environmental regulations.
Technical characteristics and process advantages
CRH2512J160RE04Z is manufactured using thick film technology, with high-purity alumina ceramic substrate as the carrier. Ruthenium based oxide resistor paste is precisely printed on the surface of the substrate and sintered at high temperature to form a stable resistor layer. Its technical characteristics and process advantages are as follows:
High power density: By optimizing the thickness of the resistance layer and the structure of the terminal electrode, the traditional 1W power limit of the 2512 package is broken, and the power density is increased by 100%, effectively saving PCB space and improving automation production efficiency.
Excellent heat dissipation performance: The ceramic substrate and large-area end design reduce thermal resistance, combined with a double-layer glass glaze protective layer, enhancing corrosion resistance and moisture resistance, ensuring long-term stable operation under high current conditions.
Surge and pulse resistance capability: capable of withstanding 100A pulse current impact within 5ms, suitable for transient load scenarios such as high-frequency switching power supplies and motor control, to avoid device failure during circuit startup or insertion and removal.
High reliability: Through 85 ℃/85% RH dual 85 humidity and heat testing, the resistance drift rate is controlled within 0.5%, meeting the requirements of industrial grade humidity and heat resistance; Adopting an anti sulfurization electrode structure, long-term operation in sulfur-containing environments will not result in resistance drift or open circuit failure.
Application scenarios and market value
CRH2512J160RE04Z stands out in the following scenarios due to its high power, wide temperature stability, and high reliability:
Industrial control: used for current sampling and current limiting protection of PLCs, frequency converters, and servo drives. The 2W power level can directly replace traditional plug-in resistors, saving PCB space and improving automation production efficiency.
Automotive Electronics: Passed AEC-Q200 certification, applied to battery management systems (BMS), LED driver circuits, and car charger control boards, capable of withstanding high temperature and vibration environments.
Communication equipment: As a load resistor in the power module of the base station, it withstands the transient voltage surge of the high-frequency switching power supply and ensures signal integrity with a temperature coefficient of 100ppm/℃.
Power management: Used for buffering absorption circuits in switch power supplies and current limiting resistors in RC Snuber networks, effectively suppressing transient voltage spikes in switches.
