RALEC(旺诠)作为国内被动元件领域的资深厂商,其推出的RTA03-4D1001FTP是一款专为空间紧凑、轻载电路设计的4路集成排阻,兼顾了集成度、精度与成本优势,广泛适配消费电子、工业控制等多类场景。
这款排阻的核心定位是通用型中小功率集成电阻,针对需要多组相同阻值电阻且PCB空间有限的设计需求。其关键特性可总结为“四合一集成、常规精度、轻载适配”:
该排阻集成4个完全独立的电阻单元,每颗阻值为1kΩ(电阻代码“1001”,即100×10¹=1000Ω)。4个电阻在封装内相互独立,可分别用于不同电路支路(如上拉、下拉、分压等),无串扰风险,适合多路相同功能的电路设计。
单颗电阻额定功率62.5mW,结合1kΩ阻值,最大允许电流约7.9mA(I=√(P/R))。实际使用建议降额50%以上(实际功耗≤31.25mW,电流≤5.6mA),避免长期过热导致阻值漂移或寿命缩短。
该排阻采用1206(英制,3216公制)表面贴装封装,单颗电阻单元为0603(0.06×0.03英寸)小封装,4个单元集成后整体尺寸仅1206,比单独贴装4颗0603电阻节省约30%的PCB面积,同时减少贴装次数,降低生产损耗。
采用8引脚单排封装,每两个引脚对应一个独立电阻单元(共4组),引脚间距符合标准SMT工艺要求,兼容多数自动贴片机的贴装精度,无需特殊治具。
基于其集成度、精度与功率特性,RTA03-4D1001FTP主要适配以下场景:
RALEC(旺诠)拥有30余年被动元件生产经验,产品符合RoHS 2.0、REACH等环保标准,通过IEC 60115、JIS C 5201等国际可靠性认证:
这款排阻以高集成度、常规精度与可靠性能,成为中小功率电路设计的高性价比选择,尤其适合需要简化布局、降低成本的批量生产项目。

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.
