In SMD resistor selection, the combination of 1206 package, 560Ω resistance, and 0.5W power rating is a common requirement in power management and industrial control circuits. The Ever Ohms CRH1206F560RP05Z is a high-power thick film chip resistor designed for this demand. This article provides a systematic analysis of the 1206 560R 0.5W Ever Ohms resistor from four dimensions: part number encoding, electrical characteristics, technical advantages, and application scenarios.
Part Number Decoding
The CRH1206F560RP05Z follows Ever Ohms' standardized encoding system. "CRH" designates the high-power thick film chip resistor series, distinguishing it from the standard-power CR series. "1206" indicates the imperial package size, corresponding to metric 3216 (3.05mm × 1.60mm). "F" represents ±1% resistance tolerance. "560R" denotes a nominal resistance of 560Ω. "P05Z" is the manufacturer's internal code for power specification and packaging [9†L8-L11].
Key Electrical Parameters and Power Density
The CRH1206F560RP05Z offers a nominal resistance of 560Ω, ±1% tolerance, 0.5W (1/2W) rated power, ±100ppm/°C temperature coefficient, and an operating temperature range of -55°C to +155°C [9†L11-L16]. The product complies with EU RoHS Directive (2011/65/EU) and does not contain REACH SVHC substances [10†L11-L12].
The power density breakthrough is the defining feature of this 1206 560R 0.5W Ever Ohms resistor. Standard 1206 thick film resistors typically carry a rated power of only 0.25W. The CRH series doubles this to 0.5W within the same physical footprint by optimizing ceramic substrate thermal paths, refining resistive paste composition, and enhancing electrode heat dissipation structures [11†L12-L14]. This means engineers can meet power margin requirements with a single component instead of paralleling two resistors or upgrading to a larger package.
The CRH series maintains a temperature coefficient of ±100ppm/°C, notably better than the ±200ppm/°C to ±400ppm/°C typical of standard CR series resistors in equivalent packages [11†L14-L15]. Lower thermal drift translates to more stable resistance values under temperature fluctuations—critical for industrial power supplies operating at sustained full load or automotive electronics in wide-temperature environments.
Materials and Process
The CRH series employs a high-alumina ceramic substrate (≥96% Al₂O₃) combined with a ruthenium-based thick film resistive layer and a three-layer termination electrode structure [15†L17-L18]. During manufacturing, ruthenium-based oxide paste is sintered at high temperature onto the alumina substrate, with a glass glaze protective layer applied on the surface for moisture and corrosion resistance. Ever Ohms holds ISO-9001 and IATF 16949 certifications, with select product lines meeting AEC-Q200 automotive electronic testing standards [8†L9-L10].
Typical Applications
The 1206 560R 0.5W Ever Ohms resistor serves multiple functional roles in circuit design:
Switching power supply feedback divider networks. In AC-DC and DC-DC power supply secondary feedback loops, the 560Ω value is commonly used for feedback voltage division and reference voltage regulation. The 0.5W power margin prevents feedback resistor failure under abnormal output conditions [16†L18-L20].
LED lighting driver current limiting. The 560Ω value functions as a current-limiting resistor in LED driver circuits. The 0.5W power rating provides thermal stress margin that extends device lifespan compared to standard 0.25W resistors [16†L5-L6].
Industrial control and communication equipment. In signal conditioning circuits for industrial inverters and servo drives, this part is used for current limiting, voltage division, and biasing. Its -55°C to +155°C operating range suits demanding industrial environments [16†L15-L16].
Consumer electronics. In control boards for air conditioners, refrigerators, and similar appliances, this resistor handles power management and signal conditioning, with ±1% accuracy meeting the precision requirements of most control loops [8†L14-L16].
Power Derating and Usage Notes
The rated power of the CRH1206F560RP05Z is specified at 70°C ambient temperature. Above 70°C, power must be linearly derated according to the manufacturer's derating curve, reaching zero at 155°C [22†L15-L16]. For selection, a minimum 30% power derating margin is recommended, along with verification that PCB copper area provides adequate heat dissipation [19†L12-L13].
