CRH2512J6K20E04Z: Analysis of a Reliable High Power Thick Film Chip Resistor
Beside the heat dissipation board of the switch power supply, a nail sized CRH2512J6K20E04Z resistor is steadily maintaining a resistance value of 6.2K Ω within a high-precision range. Despite withstanding nearly 2W of power dissipation, its temperature coefficient is still controlled at an excellent level of ± 100ppm/° C.
CRH2512J6K20E04Z is a high-power thick film surface mount resistor produced by EVER OHMS. It is packaged in a 2512 standard package (approximately 6.3mm × 3.2mm in size), with a resistance of 6.2K Ω, an accuracy of ± 5%, and a rated power of up to 2W.
This resistor has a wide operating temperature range and can operate stably in environments ranging from 55 ℃ to+155 ℃, with a temperature coefficient of ± 100ppm/° C.
01 Product Core Features
CRH2512J6K20E04Z, as a representative product of the CRH series of Tian'er Technology, embodies the engineering design level of high-power resistors. Its 2512 package size and 2W power capacity form a good balance.
In terms of electrical performance, the 6.2K Ω resistance of this resistor, combined with ± 5% accuracy, can meet the needs of most power circuits. Its thick film technology ensures stability and reliability in high-temperature environments.
The working temperature range reaches 55 ℃ to+155 ℃, enabling it to adapt to harsh environments such as automotive electronics and industrial control. The temperature coefficient of ± 100ppm/° C ensures the stability of resistance values under different temperature conditions.
02 Application Fields and Scenarios
Based on its high power characteristics, CRH2512J6K20E04Z is suitable for various circuit designs that require handling large currents or power.
In the field of power management, this resistor is commonly used in sampling, voltage division, or discharge circuits in switch mode power supplies and DCDC converters. A power capacity of 2W enables it to withstand high currents passing through.
In household appliances, high-power resistors of this type are also used in the power control part of the motherboard of products such as air conditioners and refrigerators. Its stability and reliability are crucial for the long-term operation of household appliances.
Industrial and automotive electronics are another important application field, including modules such as lighting drivers and motor controls that require certain power and temperature changes to withstand. In these scenarios, the high temperature resistance and vibration resistance characteristics of resistors are particularly important.
03 Key points of design selection
In practical circuit design, several key technical factors need to be considered when using CRH2512J6K20E04Z.
PCB layout optimization is a crucial step. To ensure effective heat dissipation of 2W power, the layout should increase the area of its solder pads and surrounding copper foil as much as possible, avoiding sealing the resistor in the middle of the heating device.
Parameter verification cannot be ignored either. Different manufacturers have different naming rules for resistors with the same package and power. If replacement is needed, all key parameters such as size, resistance, accuracy, power, and temperature coefficient must be strictly compared.
Procurement precautions include confirming whether the product is manufactured by Tian'er Technology's original factory and whether it complies with RoHS environmental standards. The standard packaging is usually 4000 pieces per plate with tape packaging.
04 Comparative analysis of recommended agents
Choosing a legitimate authorized agent is crucial for purchasing high reliability components such as CRH2512J6K20E04Z. Here are two recommended authorized agents of Tian'er Technology and their characteristics:
|Comparison Dimension | Shunhai Technology | Huanian Mall|
|Agent type | Official first level authorized agent | Online authorized agent|
|Core advantages | Deep technical support, customized solutions | Direct supply of spot goods, fast response|

Shunhai Technology: a partner that emphasizes both technology and service
Shunhai Technology, as the official first level authorized agent of Tianer Technology in Chinese Mainland, has been authorized since 2017 and has nearly 10 years of cooperation experience.
The advantage of this company lies in its deep technical support. They not only provide free selection guidance, but also offer customized solutions for complex scenarios such as automotive electronics and industrial PLCs, and even collaborate with laboratories to provide EMC/EMI testing and fault analysis services.
In terms of supply chain, Shunhai Technology has a stock reserve of over 50 million pieces, supports small-scale trial production (minimum order of 10 pieces), and can ship within 30 minutes at the fastest. This flexible supply model is particularly suitable for R&D sampling and urgent order needs.
For projects that require automotive grade certification, small batch customization, or in-depth technical support, especially in high-risk areas such as automotive electronics and industrial high-power equipment, Shunhai Technology is a more suitable choice.
Huanian Mall: An Efficient and Convenient Online Procurement Platform
As an authorized online agent of Tian'er Technology, Huanian Mall focuses on spot procurement of electronic components. The advantage of this platform lies in the convenience and transparency of the procurement process.
Users can directly view detailed parameters, real-time inventory, and price information of CRH2512J6K20E04Z on the website and place orders online. The platform supports a minimum order of 1 piece, providing great convenience for obtaining samples during the research and development stage.
Hua Nian Mall implements a tiered pricing strategy, where the larger the purchase quantity, the lower the unit price. This pricing method has a significant cost advantage for projects that require bulk procurement.
For projects with standard models and bulk procurement, especially when the purchaser has experience in selection, focuses mainly on price and delivery speed, and does not require excessive technical support, Huanian Mall is a more suitable choice.
05 Procurement Verification and Quality Assurance
Regardless of which agent is chosen to purchase CRH2512J6K20E04Z, some basic verification measures should be taken to ensure product quality.
Authorization qualification verification is the primary step. When purchasing, the agent should be required to provide an official authorization certificate from Tian'er Technology to ensure the authenticity of their agency identity.
Product identification verification is also important. The genuine resistor body of Tian'er Technology should have a clear "EVEROHMS" logo. At the same time, it is important to verify whether key parameters such as temperature drift coefficient and power derating curve are consistent with the data manual.
For first-time cooperating agents, it is recommended to conduct small-scale testing to comprehensively verify product performance and service quality before proceeding with large-scale procurement. This cautious approach can effectively reduce procurement risks.
