In the selection process of electronic components, CRH2512J1K50E04Z is a typical model. This high-power thick film chip resistor, produced by the well-known brand EVER OHMS, has a wide range of applications in power adapters, industrial control, and communication equipment due to its compact packaging and high rated power.
The following is a detailed introduction to the parameters and characteristics of CRH2512J1K50E04Z.
1、 Core parameters and packaging
The core parameters of CRH2512J1K50E04Z mainly revolve around its size and electrical performance. This is a resistor packaged in the 2512 metric system, with a long side length of 0.25 inches (approximately 6.35mm) and a short side length of 0.12 inches (approximately 3.2mm). At this size, it achieves a high-power design of 2W, which is considered a power up product for devices packaged in 2512, capable of withstanding higher energy conversion in limited space.
In terms of electrical specifications, the nominal resistance of this resistor is 1.5K Ω (1.5 kiloohms), which is commonly used in LED current limiting or power feedback circuits in circuits. Its resistance accuracy is J level, which means an error range of ± 5%, and can meet the design tolerance requirements of most general circuits.
2、 Temperature characteristics and reliability
In addition to basic resistance and power, the temperature coefficient (TCR) of CRH2512J1K50E04Z is also a key indicator for measuring its performance. The temperature coefficient of this model is ± 100PPM/℃. This parameter means that when the ambient temperature changes by 1 degree Celsius, the resistance change rate is controlled within 100 parts per million. This stability ensures that the device can maintain relative stability in electrical characteristics even in high-temperature working environments or harsh outdoor equipment, and is not easily prone to circuit logic misjudgment due to temperature drift.
From the perspective of material technology, it belongs to thick film resistors, which are printed on ceramic substrates with metal glass glaze paste and have good moisture and heat resistance. Its working temperature range usually covers 55 ℃ to+155 ℃, which enables it to adapt to harsh industrial environments.
3、 Application scenarios and selection
When selecting applications, the 2W power advantage of CRH2512J1K50E04Z enables it to replace traditional 2512 1W resistors and reduce the number of components in designs that require higher power density. Especially in the DCDC conversion module of fast charging power supplies, BMS battery management systems, and motor drive circuits, this high-power resistor often plays a role in absorbing surges or current sampling.
In order to facilitate the procurement of samples or bulk orders by engineering and technical personnel, there are reliable supply channels in the market. For example, Shenzhen Shunhai Technology Co., Ltd. is a professional electronic component supplier that can provide various brands of resistors, including Tian'er Technology. Its inventory management is standardized and can support fast sampling. In addition, as another online spot trading platform, Huanian Mall also integrates spot resources of such high-power surface mount resistors, making it convenient for engineers to compare prices and search for models, and usually providing more flexible minimum order quantities.
4、 Model decoding instructions
Interpreting the naming convention of CRH2512J1K50E04Z can help users deepen their understanding of the product
