1206W4F470JT5E 是 UNI-ROYAL(厚声)推出的一款厚膜贴片电阻,封装为常见的1206(公制尺寸约3.2 mm × 1.6 mm)。标称阻值为47Ω,精度±1%(J级),额定功率250 mW,工作电压200 V,温度系数(TCR)为±200 ppm/℃,工作温度范围为-55℃至+155℃。该器件适用于一般电子设备中的阻抗匹配、限流、分压等场合,兼顾体积与功耗的平衡。
该厚膜电阻在-55℃至+155℃温度范围内工作,满足一般工业环境的热循环及高低温要求。厚膜工艺对抗潮湿和机械冲击有良好表现,但在长期高功耗条件下需注意热耗散与热应力。对于关键应用建议参照制造商提供的可靠性试验数据(如湿热、温度循环、振动与焊接热稳性)来评估。
标准型号为 1206W4F470JT5E,品牌 UNI-ROYAL(厚声)。在批量采购前请向供应商索取最新数据手册和封装尺寸图,以确认包装方式、试验报告与可追溯性(批次信息)。如应用对温漂、可靠性或特殊认证(如汽车级)有更高要求,请与厂商确认是否有相应型号或定制方案。
总结:1206W4F470JT5E 是一款适用于通用电子和工业场合的厚膜贴片电阻,结合1206封装的安装便利性和±1%阻值精度,适合在对体积、成本与性能均有平衡要求的电路中使用。

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.
