1206W4J0220T5E 是 UNI-ROYAL(厚声)提供的一款厚膜贴片电阻,封装为常用的 1206(3216公制)尺寸。标准阻值 22Ω,阻值精度 ±5%,额定功率 250mW,适用于各种通用电子线路和功率受限的应用场景,兼顾成本与可靠性。
该型号在规定环境与施工条件下可长期工作;工作温度覆盖-55℃至+155℃,适合宽温区应用。作为厚膜电阻,其耐焊接热、机械强度和长期老化特性虽优于某些低端类型,但在高精度或高稳定性场合仍建议采用薄膜或金属箔电阻。为保证长期可靠性,应避免超出额定功率和长期处于高温高湿环境。
如需更详细的电气曲线、热阻参数、焊接工艺曲线或样片测试报告,可联系供应商索取官方数据手册与样品。

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.
