RALEC(旺诠)RTA02-4D201JTH是一款4位通用型贴片排阻,集成4个独立电阻于紧凑封装内,专为低功率、高密度PCB设计场景打造。其核心特征可概括为:体积迷你、功率适配小电流电路、精度适中、温度稳定性良好,是消费电子、小型工业设备等领域的基础被动元件选择。
该排阻的核心参数直接决定其适用场景,具体解读如下:
该排阻采用SMD 2×1mm封装(标注“0402×4”,即每个集成电阻为0402封装尺寸),体积仅为常规单电阻的4倍左右,但可替代4个独立0402电阻,大幅节省PCB空间,尤其适合智能手机、智能穿戴等对体积要求严苛的产品。 封装材质为耐高温陶瓷基,焊接兼容性良好,支持回流焊、波峰焊等标准贴片工艺,无铅环保(符合RoHS 2.0标准),适配现代电子制造的环保要求。
因参数特性适配低功率、小体积需求,RTA02-4D201JTH的典型应用场景包括:
RALEC(旺诠)是台湾老牌被动元件制造商,专注电阻研发生产超过30年,产品通过ISO 9001、IATF 16949(汽车级)等认证,RTA02-4D201JTH的可靠性体现在:
综上,RTA02-4D201JTH凭借紧凑体积、稳定性能与亲民成本,成为中小功率电子设备的理想排阻选择,适配多种主流应用场景的基础阻抗需求。

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.
