CRH1206F806RP05Z 1206 Chip Resistor with 806Ω Resistance 0.5W Power and ±1%

CRH1206F806RP05Z 1206 806R 0.5W Ever Ohms Resistor — Product Features

1. Product Overview

The CRH1206F806RP05Z is a high-power thick-film chip resistor manufactured by Ever Ohms Technology, belonging to the CRH product family. This part comes in a 1206 package with a nominal resistance of 806Ω (marked as 806R), a tolerance of ±1% (F-grade), a rated power of 0.5W, and a temperature coefficient of ±100ppm/°C. The defining characteristic of this series is that it achieves 0.5W within a standard 1206 footprint — conventional 1206 thick-film resistors are typically rated at only 0.25W. The CRH series doubles the power density through optimized material formulations and structural enhancements.
Ever Ohms, headquartered in Taiwan, is a specialized chip resistor manufacturer. Its CRH high-power thick-film resistor series is widely used in consumer electronics, home appliances, communications equipment, power supplies, and industrial measurement instruments.

2. Key Electrical Specifications

表格

The 806R value is a non-integer standard value in the E96 series, commonly found in circuits requiring precise voltage division or impedance matching. Combined with ±1% tolerance and ±100ppm/°C TCR, this resistor maintains controlled resistance drift across the full -55°C to +155°C temperature range, making it suitable for applications demanding parameter consistency.

3. Technical Features and Advantages

High Power Density
The CRH1206F806RP05Z delivers 0.5W in a 1206 package, a 100% increase over conventional thick-film resistors of the same size. This improvement stems from three optimizations: the use of a high-thermal-conductivity ceramic substrate, an improved power-handling resistive paste formulation, and enhanced heat dissipation through the termination electrode structure. For designs with limited PCB space but higher power demands, selecting this 1206 806R 0.5W Ever Ohms resistor avoids the need to step up to a larger package such as 2010 or 2512, saving board-level area.
Wide Temperature Range Operation
The operating temperature range spans -55°C to +155°C, with rated power referenced to a 70°C ambient. When the actual operating environment exceeds 70°C, load power must be derated linearly according to the power derating curve, reaching zero at 155°C. This derating mechanism complies with JIS-C-5201-1 and IEC-60115-1 standards, ensuring reliability over long-term operation.
Reliable Terminations and Solder Resistance
CRH series terminations employ a multi-layer metallization structure, providing good solderability and resistance to soldering thermal shock. Per the datasheet, after immersion in solder at 260±5°C for 10 seconds, resistance change for ±1% parts does not exceed ±(0.5% + 0.05Ω); the same limit applies after solvent resistance testing. The product is compliant with EU RoHS and REACH regulations — lead-free and cadmium-free — meeting export compliance requirements for green electronic products.
Overload and Endurance Performance
The short-time overload test applies 2.5 times the rated working voltage (or the 400V maximum overload voltage, whichever is lower) for 2 seconds, after which ±1% parts show resistance change within ±(1.0% + 0.05Ω). The load-life test runs at 70°C with rated voltage for 1000 hours (1.5 hours ON, 0.5 hours OFF cycling), and resistance drift remains within the same limits. These metrics reflect the resistor's long-term stability under continuous power dissipation.

4. Typical Applications

The parameter combination of the CRH1206F806RP05Z suits the following applications:

• Power management circuits: Voltage-divider sensing and feedback loop setting in switching power supplies, where the 0.5W power margin handles transient power fluctuations.
• Home appliance control boards: Signal conditioning and current limiting on main control boards of air conditioners and refrigerators, with the wide temperature range accommodating internal device heating.
• Communications equipment: RF matching and baseband biasing circuits in mobile phones, routers, and fax machines, where ±1% tolerance ensures signal parameter consistency.
• Industrial measurement instruments: Precision voltage division and reference setting in electricity meters and navigation devices, with low TCR minimizing temperature-induced measurement errors.
• LED lighting drivers: Current-setting resistors in constant-current drive circuits, where the higher power rating reduces self-heating effects on surrounding components.

5. Selection and Design Considerations

When selecting the 1206 806R 0.5W Ever Ohms resistor for circuit design, the following points warrant attention.
Actual power dissipation should include margin. Although rated at 0.5W, long-term operating power is recommended to stay below 70% of rating — i.e., no more than 0.35W — to slow resistive film aging and extend service life.
PCB pad thermal design affects real-world power performance. The CRH series power rating is based on standard test board conditions. If the actual PCB has insufficient copper area or inadequate thermal paths, component temperature rise will exceed the datasheet baseline, requiring further derating. Sufficient copper area should be reserved under the resistor pads, with thermal vias added when necessary.
Since 806Ω is a non-common value, BOM management should verify supply chain stock availability. For mass-production projects, lead time and minimum packing quantity should be confirmed with distributors in advance. The CRH1206F806RP05Z is supplied in tape-and-reel packaging: 5,000 pieces per 7-inch reel and 10,000 pieces per 10-inch reel.
