CRH Series 2512 Chip Resistor with 24Ω Resistance 2W Rated Power and ±1% Tolerance

TT Electronics, a global leader in passive components, employs a rigorous part numbering system. Taking CRH2512F24R0E04Z as an example, each segment conveys specific technical information:

• CRH: Thick-film chip resistor series designation, indicating high-reliability resistors manufactured using thick-film technology;

• 2512: Package size code in imperial units, corresponding to 6.4mm * 3.2mm (length * width), classified as a large-size surface-mount package;

• F: Tolerance grade, where F denotes ±1% resistance tolerance, meeting precision circuit design requirements;

• 24R0: Resistance value code, where R represents the decimal point, meaning 24.0Ω or 24R;

• E04: Packaging and process code, typically indicating tape-and-reel quantity and environmental compliance standards;

• Z: Lead-free environmental identifier, compliant with RoHS directives.

From the part number alone, one can identify this as a 2512 24R 2W resistor featuring large package dimensions, high power rating, and excellent precision.

This 2512 24R 2W resistor utilizes an alumina ceramic substrate with a ruthenium-based thick-film resistive element fired at high temperature. The terminal electrodes adopt a three-layer structure (silver/nickel/tin) to ensure soldering reliability and long-term stability. The 2W rated power within a 2512 package represents a high-power-grade classification with superior heat dissipation performance, making it suitable for high-current sensing and power distribution applications.
