RMS12FT1503是大毅科技推出的一款1206封装厚膜片式电阻,针对工业控制、汽车电子、消费电子等领域的常规电路需求设计,兼具宽温稳定性、高性价比与通用兼容性,是中低压电路中电阻分压、电流采样、信号调理的理想选择。
该产品由台湾知名电子元器件厂商大毅科技(Yageo)生产,采用成熟的厚膜电阻工艺:以高纯度氧化铝陶瓷为基底,通过丝网印刷精密电阻浆料并经高温烧结形成电阻层,表面覆盖玻璃釉保护层,兼具机械强度与耐环境性能。
产品采用1206英寸封装(对应公制尺寸3.2mm×1.6mm×0.5mm),是SMT(表面贴装技术)领域的通用封装形式,可兼容绝大多数自动化贴装生产线,便于批量生产应用。
型号“RMS12FT1503”中:
标称阻值为150kΩ,精度等级为**±1%**,可满足对阻值准确性要求较高的电路设计(如传感器信号分压、精准电流采样电路),相比±5%精度电阻的应用场景更广泛。
温度系数为**±100ppm/℃**,表示温度每变化1℃,阻值变化量为±15Ω(150kΩ×100×10⁻⁶)。该系数在厚膜电阻中属于中等偏优水平,可有效降低宽温环境下的阻值漂移,提升电路稳定性。
产品支持**-55℃至+155℃**的工作温度范围,覆盖了工业控制(-40℃+85℃)、汽车电子(-40℃+125℃)等场景的极端温度需求,无需额外的温度补偿电路。
RMS12FT1503凭借上述优势,成为中低压电路设计中平衡性能与成本的优选厚膜片式电阻。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
