0402WGF6191TCE 是 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装为 0402(约 1.0 mm × 0.5 mm),标称阻值 6.19 kΩ,阻值精度 ±1%,额定功率 62.5 mW,额定工作电压 50 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ ~ +155℃。该器件以体积小、成本低、适用于高密度贴装为特点,适合低功耗信号与偏置电路应用。
0402(英制)对应常用尺寸约 1.0 mm × 0.5 mm,适合高密度贴片工艺。焊盘及锡膏设计建议参考制造商推荐的 PCB land pattern,以确保焊点可靠性与机械强度。
在选型时,关注电路中实际最高电压与电流,优先按功率导出电压限制(约 19.7 V)判断是否满足需求;若电路有较大温度变化或要求更低温漂,应考虑更小 TCR 或更高精度的产品。采购时确认包装卷带、批次及是否有质量认证(如 RoHS)等,以满足生产与可靠性要求。
以上为 0402WGF6191TCE 的产品概述及常用设计注意事项,可作为设计选型与电路验证的参考。若需进一步的规范数据表(如阻值漂移曲线、功率-温度降额曲线、回流曲线和机械冲击数据),建议向供应商索取完整规格书。

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.
