III. Product Advantages
3.1 High Power Density — Double the Power in Same Package
The most notable advantage of this 2512 24.3K 2W resistor is its power density. Standard 2512 package thick film resistors are typically rated at 1W, while the EVER OHMS CRH series achieves 2W in the same physical footprint — a 100% increase. This allows engineers to double power headroom without increasing PCB footprint.
3.2 Mature and Reliable Thick Film Technology
The CRH series employs thick film technology with 96% high thermal conductivity alumina ceramic substrate, forming a dense conductive layer through high-temperature sintering to ensure uniform current distribution and prevent localized overheating. Compared to thin film resistors, thick film offers superior cost-effectiveness and pulse handling capability.
3.3 Excellent Tolerance and Temperature Stability
±1% tolerance (F grade) combined with ±100ppm/℃ TCR makes this 2512 24.3K 2W resistor reliable in precision voltage divider and feedback networks. Compared to J-grade (±5%), F-grade significantly reduces system error.
3.4 Wide Temperature Range and High Reliability
-55℃~+155℃ operating temperature range, backed by EVER OHMS ISO-9001, ISO-TS16949 certifications and AEC-Q200 compliance, ensures stable performance under harsh conditions.
3.5 Compact Size with SMT Compatibility
The 2512 package balances power handling with SMT automation compatibility, improving production efficiency and reducing labor costs compared to traditional through-hole resistors.
