The CRH series, belonging to CRH2512J5K10E04Z, is a thick film surface mount resistor product line specially designed for high-power density applications and is also one of the core main series of Tian'er Technology.
The CRH series covers full-size packages such as 0402, 0603, 0805, 1206, 1812, and 2512, with a power range of 0.25W-3W and resistance values ranging from 0.1 Ω to 10M Ω. It can meet the diverse power needs from consumer electronics to industrial and automotive electronics. The 2512 package is a representative of the high-power series, with a rated power of 2W providing an ideal solution for compact high-power circuit design.
Core technology breakthrough
High power density: By optimizing the thick film slurry formula and ceramic substrate structure, the thickness of the resistance layer reaches over 100 μ m, and the heat dissipation efficiency is greatly improved. It can achieve a 2W power carrying capacity within a standard volume of 2512, doubling the power density compared to traditional products.
Sulfurization resistance: By using electrode alloy modification technology, the thick film structure can effectively resist the corrosion of sulfurization gases in industrial environments. Under sulfur-containing conditions, there is no significant drift in resistance value during long-term operation, and the service life is extended to over 5000 hours.
Wide temperature stability: Through rigorous testing such as 125 ℃ high-temperature aging and 85 ℃/85% RH wet heat cycle, the resistance change rate is less than 0.5% in extreme environments, making it suitable for harsh scenarios such as automotive cabins, outdoor communication, and petrochemicals.
Surge resistance: Optimized resistor and electrode design, capable of withstanding 100A pulse current impact within 5ms, suitable for instantaneous high current scenarios such as motor start-up and power switch switching, reducing the risk of circuit damage.
