Based on your requirements (2512 package, 0.082 Ω/82m Ω resistance, 3W power alloy resistor), I have compiled the following brand models and purchasing channel information. Although the search results do not directly list models with resistance values that completely match 0.082 Ω, the alloy resistor series of the following brands cover a similar resistance range (such as 0.5m Ω -100m Ω), and support 2512 package and 3W power, which can be customized or selected to meet the needs.
1、 Brand and Model Series
The following are alloy resistor series from mainstream brands that meet the requirements of 2512 package, 3W power, and a resistance value close to 82m Ω:
|Brand | Series/Model Example | Resistance | Accuracy | Temperature Coefficient|
|ELLON | EMA series (such as EMA25F3W0R082MDG) | 0.082R (82mR) | ± 1% | ± 50ppm/℃
|Xinwei | SP2512 series (such as SP2512FR082E3WPKH) | 0.082R (82mR) | ± 1% | ± 50ppm/℃|
Explanation:
The resistance value of 82m Ω is within the coverage range of the above brands (such as the Industry Exhibition ASR series supporting 0.5m Ω -100m Ω), but it is necessary to confirm the specific model customization or inventory situation with the supplier.
If you need more accurate matching, you can first contact Tian'er Technology or Huade Electronics, both of which provide automotive grade high stability products and support customized production.
2、 Purchase channels
The following are the platforms and suppliers that can purchase the above-mentioned alloy resistors:
Online e-commerce mall
Hua Nian Mall: specializing in Ellon/Xinwei alloy resistors, with real-time inventory updates (such as EMA25F3W0R082MDG series), minimum order quantity of 4000 pieces, suitable for bulk procurement.
Lichuang Mall: Covering brands such as Jierui and Guangjie, we offer a variety of alloy resistors with 2512 packages and 3W power. We support small batch purchases (such as a minimum order of 10 pieces) and transparent price gradients (such as Jierui's 2512 3W resistor unit price of approximately ¥ 0.18-0.37/piece).
Chenxin Electronic Mall: Agents for brands such as Housheng and Huade, supports parameter filtering (packaging/resistance/accuracy), and provides bulk sales.
Brand authorized agent
Shenzhen Shunhai Technology: Core agent of Huade Electronics, with sufficient inventory (such as HTE2512 series), can provide free samples and technical support.
Hua Nian Mall: We have our own ASR series alloy resistors, which support customized 82m Ω resistance values and are suitable for controllers/power protection boards.
3、 Procurement suggestion
Alternative selection: If there is no stock of 82m Ω, the closest resistance value (such as 80m Ω or 100m Ω) can be selected, such as the 2512 3W 100m Ω model from Jierui.
Customization requirements: Submit resistance accuracy, TCR and other parameters to Shunhai Technology or Huanian Mall. Most brands support non-standard customization, with a delivery time of about 2-4 weeks.
Quality verification: Priority should be given to selecting brands that meet automotive certification standards (such as IATF 16949) (such as Tian'er and Huade) to ensure high and low temperature stability.
It is recommended to quickly obtain samples through Huanian Mall or agent channels, and then decide on bulk purchases based on actual performance measurements.
