As the core component for current sampling and power control, Tai alloy resistors have a product line covering multiple series to meet high-precision and high-power requirements in different scenarios. According to the search results, the main series and characteristics are as follows:
RL series
Features: Targeting low to medium power applications, using standard surface mount packaging, with low temperature coefficient (T.C.R) and high stability.
Typical model:
RL12FTNR180 (1206 package, 0.18 Ω, 1/2W, ± 1% tolerance, T.C.R ± 200ppm/℃)
The naming convention for RL series models is "RL+size code+tolerance code+packaging code+resistance code". For example, "RL12 10 F TN R180" corresponds to 1206 packaging, 1/2W, ± 1% tolerance, lead-free paper tape packaging, and 0.18 Ω resistance.
Application scenarios: power management, circuit current control, automotive electronics (compliant with AECQ200 standard), etc.
RLM series
Features: Specially designed for high-precision sampling, using alloy materials to achieve ultra-low resistance (as low as 3m Ω), supporting higher power (1W~2W) and wider temperature range.
Typical model:
RLM12FTCMR003 (1206 package, 3m Ω, 1W, ± 1% tolerance, ± 50ppm/℃ T.C.R)
RLM12FTCMR008 (1206 package, 8m Ω, 1W)
RLM25FEER004 (2512 package, 4m Ω, 2W, ± 75ppm/℃ T.C.R)
Application scenarios: battery protection boards, power tools, LED lighting, power converters, and other scenarios that require current feedback or overcurrent protection.
RLP series
Features: Designed for high power requirements, with a maximum power of up to 3W, using anti-corrosion and anti sulfurization processes, suitable for harsh environments.
Typical model:
RLP25FEGR020 (2512 package, 0.02 Ω, 3W, ± 1% tolerance)
Application scenarios: fields with high reliability requirements such as automotive electronics, industrial power supplies, and electricity meters.
Other supplementary information
The correspondence between packaging and power:
1206 Package: Power coverage from 1/2W (RL series) to 1W (RLM series).
2512 package: power increased to 2W~3W (RLM, RLP series).
Environmental certification: Most series comply with lead-free environmental standards and have passed quality system certifications such as ISO9001 and QS9000.
