RALEC(旺诠)RTA03-4D100JTP是一款专为高密度电路设计的小型化表面贴装排阻,集成4个10Ω独立电阻,具备体积小、一致性好、可靠性高的特点,广泛适配消费电子、工业控制等中小功率电路场景。
该排阻属于4位独立电阻集成封装,核心定位是替代4个离散0603电阻,通过集成设计实现两大价值:
核心属性可概括为:10Ω×4独立电阻、±5%精度、62.5mW/单个功率、±200ppm/℃温度系数、8引脚1206封装。
标称阻值为10Ω(型号中“100”对应10×10⁰Ω),精度等级为**±5%**(“J”为E24系列精度代码),满足大多数工业控制、消费电子的常规应用需求,无需额外校准。
单个电阻额定功率62.5mW,4个电阻集成于1206封装后,整体散热面积优于4个离散0603电阻(0603封装面积仅为1206的1/4),实际使用中若4个电阻同时工作,总功率可稳定承载250mW左右,无需额外散热设计。
温度系数为**±200ppm/℃,即环境温度每变化1℃,阻值变化±0.02%。结合工作温区-55℃~125℃**计算,最大阻值漂移约±0.35Ω,可满足常规宽温环境下的性能稳定性。
整体采用1206英制封装(对应公制3.2mm×1.6mm×0.5mm),内部集成4个0603(1.6mm×0.8mm)电阻单元,封装材料为陶瓷基片+环氧树脂,具备良好的抗冲击、抗振动性能,符合表面贴装工艺要求。
采用8引脚双列表面贴装(SOIC-like布局),每个电阻对应2个独立引脚,无共接端设计,可灵活实现4个电阻的串联、并联或独立使用,适配不同电路拓扑结构(如分压、限流、匹配网络等)。
因集成度高、一致性好,该排阻主要应用于以下场景:
RALEC(旺诠)是台湾老牌被动元件制造商,成立于1985年,产品覆盖电阻、电容等领域,具备三大优势:
综上,RALEC RTA03-4D100JTP排阻以高集成度、稳定性能与成本优势,成为中小功率电路中替代离散电阻的理想选择,广泛适配多领域的高密度设计需求。
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.
