EVER OHMS's CRH series high-power thick film surface mount resistors are widely recognized in industrial, automotive, and consumer electronics fields for their excellent performance and stable supply system. The following are the core advantages and supply characteristics of this series:
1、 Product technical advantages
1. High power density and heat dissipation performance
The CRH series achieves high power carrying capacity in small-sized packaging through thick film technology and optimized heat dissipation design. For example:
2512 Package: Power up to 2W, suitable for high load scenarios such as power circuits and motor drivers
1206 package: power 0.5W, 1812 package: power 1W, balancing compact layout and efficient heat dissipation
Wide working temperature range (55 ℃~155 ℃), excellent temperature rise control, ensuring high temperature environment stability.
2. Accurate and reliable electrical parameters
Wide range of resistance values: from 1 Ω to several hundred K Ω (such as 120K Ω, 390 Ω, etc.), meeting diverse design requirements
Accuracy can be selected as ± 5% (universal type) or ± 1% (high-precision model), with a temperature coefficient as low as ± 100ppm/℃.
3. Robustness and long lifespan
Adopting a ceramic substrate and metal electrode reinforced structure, with overvoltage resistance (300V) and sulfur resistance design, it is suitable for harsh industrial environments.
2、 Widely covered application scenarios
The CRH series is suitable for high-power demand scenarios in multiple fields:
Power management: Switching power supply, rectifier, UPS system
Automotive electronics: motor drive, battery management system, charging station
Medical equipment: Defibrillators, ventilators, dialyzers
Consumer electronics: high-power LED drivers, smart home appliances (air purifiers, induction cookers).
3、 Supply assurance and procurement advantages
1. Spot inventory and quick response
Mainstream models (such as CRH2512 and CRH1206) are provided with a large amount of stock by authorized distributors (such as Chenxin Electronics and Huanian Mall), supporting delivery within 72 hours.
The standard packaging is 4000 pieces per plate, with a clear minimum order quantity to reduce procurement uncertainty.
2. Ladder pricing and cost optimization
Batch purchases can enjoy tiered discounts, such as:
CRH2512J120KE04Z（120KΩ）：
5000+unit price ¥ 0.10695 (market price approximately ¥ 0.11459)
CRH1812J390RE04Z（390Ω）：
5000+unit price ¥ 0.05750.
3. Model compatibility and alternative solutions
Provide cross brand alternative options (such as Guoju, Weishi, ROHM) to ensure seamless switching in case of out of stock.
The entire series supports model customization to meet special parameter requirements.
4、 Selection suggestions
Match key parameters according to application requirements:
|Parameter requirements | Recommended model examples | Typical application scenarios|
|High power (2W) | CRH2512J120KE04Z (120K Ω) | Power circuit, industrial driver|
|Medium power (0.5W1W) | CRH1206F560RP05Z (560 Ω) | Communication equipment, home appliance control board|
|High precision (± 1%) | CRH0805F4K70P05Z (4.7K Ω) | Medical instruments, precision sensors|
Tip: When selecting, it is necessary to comprehensively evaluate the power margin (recommended to reserve more than 20%), heat dissipation conditions (such as PCB copper foil area), and voltage tolerance value.
The Tian'er CRH series has become the preferred choice for high-power circuit design due to its high reliability, power density, and flexible supply. By purchasing through authorized channels (such as Chenxin Mall and Huanian Electronics), users can receive genuine factory guarantees and bulk price support. For specific model parameters or alternative solutions, it is recommended to directly query the distributor platform for real-time inventory and technical support.
