RMS04FT2492是大毅科技推出的一款小功率高精度厚膜贴片电阻,采用0402封装,专为高密度、低功耗电子电路设计,兼顾稳定性与成本效益,广泛适配工业、消费电子、汽车电子等多领域应用需求。
该电阻属于厚膜贴片电阻系列,核心定位为小功率(62.5mW)、高精度(±1%)、宽温适应性的基础电子元件,主要用于电路中的分压、限流、信号调理等基础功能,解决高密度PCB布局下的小尺寸电阻需求,同时满足极端温度环境下的性能稳定。
阻值标称24.9kΩ(对应电阻代码2492,即249×10²Ω),精度等级为**±1%**,属于工业级常规高精度标准,可满足多数电路对电阻值偏差的控制要求,避免因阻值误差导致的信号偏移或功率损耗异常。
采用厚膜工艺制造,以陶瓷基板为载体,通过丝网印刷电阻浆料、烧结等工序形成电阻层,具有成本适中、稳定性好、抗机械应力能力强等特点,相比薄膜电阻成本更低,相比线绕电阻尺寸更小。
该电阻采用0402封装(英制尺寸:长0.04英寸×宽0.02英寸;公制尺寸:1005,即长1.0mm×宽0.5mm),是贴片电阻中尺寸较小的封装之一,优势如下:
大毅科技是国内专业的电子元器件制造商,专注于电阻、电容等被动元件的研发与生产,产品通过ISO9001、IATF16949等质量体系认证,在汽车电子、工业控制领域拥有稳定的客户群体。
RMS04FT2492经过多项可靠性测试验证,包括:
RMS04FT2492因小尺寸、宽温稳定、高精度的特点,广泛应用于以下场景:
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
