The following is a compilation of selection information for 2512 package (size 6.4mm × 3.2mm) and 1.8 Ω (1.8R) surface mount resistors. Based on the search results, the specific model and key parameters are analyzed as follows:
1、 Clear model: 2512 1.8R ± 1%
Parameter description:
Resistance: 1.8 Ω (nominal value)
Accuracy: ± 1% (typical accuracy)
Package size: 2512 (length 6.35mm x width 3.2mm)
Typical application scenarios: electronic device maintenance (such as mobile phone circuit boards), precision circuit design (amplification/filtering circuits), communication equipment signal processing, and other fields that require high resistance accuracy.
2、 Reference for similar resistance models (indirect alternative solution)
If the inventory of the 1.8 Ω model is insufficient, the following 2512 package models with similar resistance values (such as 1.8 Ω or low resistance) can be considered, and attention should be paid to adjusting the electrical parameters:
1. High power demand scenarios (such as power modules):
EHP25FR1R80HDU: 1.8 Ω± 1%, power 3W, temperature coefficient ± 400ppm/℃, suitable for high load scenarios such as motor drive.
Guoju RC2512JK7W1R8L: 1.8 Ω± 5%, power 2W, low cost (starting from ¥ 0.83/piece), suitable for consumer electronics.
2. Precision and low-temperature drift requirements (such as automotive electronics):
Vishay WSLT2512R1800FEA: 0.18 Ω (not 1.8 Ω) ± 1%, power 1W, temperature drift ± 75ppm/℃, certified by AECQ200, sulfur and moisture resistant.
EHP25FS1R80FDS: 1.8 Ω± 1%, temperature drift ± 200ppm/℃, suitable for environments with large temperature changes.
3. Surge resistant design (industrial protection):
EGM25FU1R80DDS: 1.8 Ω± 1%, power 3.5W, resistant to instantaneous impact (such as lightning strikes), in compliance with industrial standards.
3、 Selection suggestions
1. Prioritize confirming resistance requirements:
When strictly matching 1.18 Ω, choose a dedicated model (if recommended), pay attention to inventory and delivery time (some models need to be customized).
When allowing for resistance adjustment, spot models with 1.8 Ω or 0.18 Ω (such as Vishay and Guoju) are easier to purchase.
2. Key parameter trade-offs:
Power: Universal selection of 2W (such as EHP series), high load selection of 3W+(such as EGM series).
Temperature drift: Select ± 200ppm or less for automotive/industrial applications (such as EHP25FS1R80FDS), and ± 50ppm for precision instruments (such as the EGM series).
Certification: Automotive electronics require AECQ200 certification (such as Vishay WSLT series).
