RMS04FT10R0是大毅科技推出的一款常规高精度小功率厚膜片式电阻,采用0402(1005公制)小型化封装,专为高密度PCB设计、宽温环境应用及常规电子电路的阻性需求打造,具备稳定的电气性能与可靠的环境适应性。
该型号属于厚膜电阻范畴,通过陶瓷基底+厚膜电阻膜工艺实现阻值稳定,核心属性明确:
10Ω±1%的精度(25℃基准温度下,实际阻值偏差≤±0.1Ω)结合**±200ppm/℃温度系数**,可精准计算温区内的阻值变化:
温度每变化1℃,阻值变化量为±200×10⁻⁶×10Ω=±2mΩ;在-55℃+155℃的210℃温区内,最大阻值变化为±42mΩ,最终阻值范围为9.958Ω10.042Ω,仍远在±1%精度范围内,满足宽温下的性能一致性。
采用0402(英制,对应公制1005:1.0mm×0.5mm)表面贴装封装,具备以下特点:
通过丝网印刷电阻浆料→高温烧结→端电极制备等工艺制造,相比薄膜电阻成本更低,相比绕线电阻体积更小,且具备:
-55℃+155℃的工作温区覆盖了工业控制、汽车电子(次级应用)、户外设备等场景的温度波动,例如车载信息娱乐系统的-40℃+85℃、工业PLC的-25℃~+85℃均在其范围内。
该型号通过大毅科技的常规可靠性测试,核心指标符合行业标准:
RMS04FT10R0的性能适配以下场景:
大毅科技作为专业电子元器件制造商,在厚膜电阻领域具备成熟的生产工艺与品质管控体系:
综上,RMS04FT10R0是一款性价比高、性能稳定的厚膜片式电阻,适合常规电子电路的阻性需求,尤其是对体积、温区、精度有综合要求的场景。

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.
