Ever Ohms utilizes a structured part numbering system. The CRH1206J47R0P05Z part number decodes as follows:

3. Key Electrical Parameters

According to Ever Ohms official datasheets and authorized distribution channels, the key parameters of CRH1206J47R0P05Z are as follows:

Compared to standard CR series 1206 thick film resistors (typically 0.25W/1/4W), the CRH1206J47R0P05Z delivers double the power rating. This “small size, high power” characteristic effectively saves PCB layout space.

4. Technical Features & Product Advantages

4.1 Superior Power Density

The CRH1206J47R0P05Z achieves 0.5W power rating in a standard 1206 package. While conventional 1206 thick film resistors typically support only 0.25W (1/4W), the CRH series achieves higher thermal dissipation efficiency through optimized thick film paste formulation, improved ceramic substrate thermal pathways, and enhanced electrode heat dissipation structures. The CRH series utilizes ruthenium-based oxide paste screen printing technology, fired at high temperature on alumina ceramic substrates to form the resistive layer.

This allows engineers to upgrade power handling capability without PCB layout changes. A single 1206 47R 0.5W resistor can replace two parallel 0.25W resistors, simplifying PCB routing and saving board space.

4.2 Excellent Temperature Stability

The ±100ppm/℃ TCR ensures stable resistance values across a wide temperature range. Compared to ±200~400ppm/℃ drift typical of conventional thick film resistors, this model offers more controllable resistance drift across the full -55℃ to +155℃ operating range, effectively preventing circuit parameter failures under extreme temperature conditions.

4.3 Wide Operating Temperature Range

The -55℃ to +155℃ operating temperature range covers applications from low-temperature environments to high-temperature industrial scenarios. Full power operation is supported at 70℃ ambient, with derating required as temperature increases.

4.4 High-Quality Substrate & Process

The resistor employs high-purity 96% alumina ceramic substrate, offering excellent thermal conductivity, insulation, and mechanical shock resistance, efficiently dissipating heat generated during operation to prevent localized overheating and component failure.

4.5 Environmental Compliance

The product complies with EU RoHS Directive (2011/65/EU) and is free of REACH SVHC substances (1907/2006/EC).

5. Typical Applications

The CRH1206J47R0P05Z 1206 47R 0.5W resistor, with its high power density and excellent temperature stability, finds wide application across multiple industries:

5.1 Power Management Circuits

Used in DC-DC converter feedback divider networks, current limiting resistors, and similar applications where the 0.5W power rating can withstand certain surge currents. In switched-mode power supply (SMPS) snubber circuits and divider networks, it leverages high power density to handle transient surges.

5.2 LED Driver Circuits

Serves as an LED current-limiting resistor; the 47Ω value paired with appropriate supply voltage provides stable drive current for small to medium power LEDs. In constant-current LED driver circuits, it can function as a current-setting element or part of the feedback divider network.

5.3 Industrial Control

Widely used in industrial control board pull-up/pull-down and signal conditioning divider circuits. In motor driver pre-charge circuits and current sensing, the 5% tolerance meets general control requirements.

5.4 Consumer Electronics

Applied in power modules, battery protection circuits, and similar applications across various consumer electronic products, handling moderate currents with stable voltage regulation.

5.5 Automotive Electronics

Suitable for automotive control boards, on-board chargers, battery management systems, and other reliability-critical applications. Ever Ohms products are AEC-Q200 automotive-grade certified.

5.6 Communication Equipment

High-power resistors are extensively used in communication equipment such as 5G base stations.
