RMS04JT682是大毅科技推出的一款0402封装厚膜电阻器,针对小型化、低功率电子设备的信号调理、偏置电路等场景优化设计,兼顾电气性能稳定性与成本优势,广泛适配消费电子、工业控制等多领域应用。
该电阻属于大毅科技常规厚膜电阻系列,型号命名遵循行业通用规则:
产品采用表面贴装工艺,端电极兼容无铅焊接,符合RoHS 2.0环保标准,支持自动化批量生产。
标称阻值为6.8kΩ,精度±5%,满足大多数通用电路的阻抗匹配、分压、限流需求——无需更高精度(如±1%)的场景下,可有效控制BOM成本。
温度系数(TCR)为**±200ppm/℃**,即每变化1℃,阻值变化约±0.02%。对于厚膜电阻而言,该TCR属于中等水平,可满足-55℃~+155℃范围内的性能稳定要求。
宽温设计:-55℃~+155℃,覆盖工业级、汽车辅助系统的温度需求,避免低温漂移或高温降额过大问题。
0402封装体积仅1.0×0.5mm,是智能手机、智能穿戴等小型设备的主流封装,可显著提升PCB布局密度,缩小设备尺寸。
采用厚膜印刷工艺制备电阻层,相比薄膜电阻成本更低,同时具备耐冲击、抗老化的稳定性;端电极采用多层镍/锡结构,提升焊接可靠性,减少虚焊风险。
大毅科技对该产品完成多项可靠性测试:
批量生产中阻值分布均匀,符合正态分布特性,可降低电路调试难度,提升量产良率。
大毅科技作为台湾地区知名被动元件制造商,拥有30余年电阻研发生产经验,产品覆盖厚膜、薄膜、功率电阻全系列,广泛应用于全球电子产业。
RMS04JT682符合以下标准:
该产品凭借小体积、宽温稳定、成本优势,成为0402封装6.8kΩ厚膜电阻的高性价比选择,适配多领域低功率电路需求。

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.
