RALEC(旺诠)推出的RTT026041FTH是一款0402封装的厚膜高精度小功率贴片电阻,专为高密度电路设计,兼顾性能稳定性与成本效益,覆盖工业控制、消费电子、通信设备等多领域应用需求。作为旺诠常规厚膜电阻系列的核心产品,该型号以精准阻值控制、宽温适应性为核心优势,适配低功耗场景下的信号调理、分压、偏置等关键功能。
产品固定阻值为6.04kΩ,精度等级为**±1%**——在25℃标准温度下,实际阻值范围为5.9796kΩ~6.1004kΩ,无需额外校准即可满足多数模拟电路对阻值偏差的要求(如传感器信号放大、音频电平调节等)。
额定功率为62.5mW,最大工作电压为50V,适配低功耗电路的功率需求;实际应用中建议遵循“功率降额原则”(实际功率不超过额定值的80%),可有效延长产品寿命并提升可靠性。
温度系数(TCR)为**±100ppm/℃**,意味着温度每变化1℃,阻值变化约0.01%。以典型工业环境(-40℃~+85℃)为例,阻值总变化量约±0.125%,对信号精度影响极小,适合宽温场景使用。
采用0402英制封装(公制约1.0mm×0.5mm×0.5mm),体积小巧,可显著提升PCB布局密度,适配智能手机、小型通信模块等对空间要求严苛的产品。
采用厚膜丝网印刷技术,通过高精度网版控制RuO₂基电阻浆料的厚度与图案,确保阻值一致性与长期稳定性;厚膜结构相比薄膜电阻更抗机械应力,适合振动环境(如车载设备)。
端电极采用Ni/Cu/Sn三层镀层:底层Ni增强附着力,中间Cu提升导电性能,表层Sn适配无铅焊接(符合RoHS标准),焊接时形成稳定的金属间化合物,减少虚焊、脱焊风险,耐老化性能优于单层镀层产品。
通过浆料配方优化与烧结工艺参数(温度、时间)精准控制,使产品在全工作温度范围内阻值漂移极小,满足工业级设备的长期可靠性要求。
支持**-55℃+155℃**工作温度,覆盖商业级(070℃)、工业级(-40℃+85℃)及部分汽车级(-40℃+125℃)场景,可用于高温烤箱、极地监测设备等极端环境。
产品经老化测试后,阻值漂移率≤0.5%(1000小时,125℃),满足工业设备5~10年的使用寿命要求。
该产品凭借精准参数、可靠工艺与宽适配性,成为高密度低功耗电路的优选电阻之一,适合对空间、精度与稳定性有综合要求的设计场景。

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.
