CRH2512J120RE04Z
CRH2512J120RE04Z is a high-power thick film chip resistor manufactured by Ever Ohms. Its core specifications are 2512 package, 120R (120Ω) resistance, and 2W rated power, belonging to the CRH high-power series.
Product Number Decoding
Ever Ohms uses a standardized coding scheme. For CRH2512J120RE04Z:
-
CRH: High-power thick film resistor series.
-
2512: Package size, metric 6432 (6.35mm × 3.18mm).
-
J: Tolerance grade, indicating ±5%.
-
120R: Resistance value, 120Ω.
-
E04Z: Suffix for TCR of ±100ppm/℃ and tape & reel packaging.
Key Features
The key advantage is high power density. In a standard 2512 package, the ordinary CR series is typically rated at 1W. The CRH2512J120RE04Z achieves 2W through optimized ceramic substrate thermal pathways and electrode structures—a 100% increase. Key specs:
-
Resistance: 120Ω
-
Tolerance: ±5%
-
Rated Power: 2W
-
TCR: ±100ppm/℃
-
Operating Temperature: -55℃ ~ +155℃
Applications
Ideal for high-reliability scenarios requiring 2W power handling:
-
Power Management: Feedback voltage divider networks or current limiting in switching power supplies.
