0402WGF6803TCE 是 UNI-ROYAL(厚声)推出的一款0402封装厚膜贴片电阻,标准阻值为 680 kΩ,公差 ±1%,标称功率 62.5 mW(即 1/16W)。器件适用温度范围宽 (-55 ℃ ~ +155 ℃),温度系数为 ±100 ppm/℃,额定工作电压为 50 V。该器件适合用于高阻值、占板面积受限且要求中高精度的表面贴装电路中。
附加电气示例计算(便于设计判断):
注意:尽管理论上由功率决定的最高安全电压可由 V = sqrt(P·R) 计算得到更高数值,但器件最大允许工作电压以厂家标注 50 V 为准,设计时不得超限使用。
提醒:厚膜电阻在高阻值与高精度场合,其电压系数(VCR)和噪声指标通常高于薄膜电阻;在对漂移、噪声极为敏感的应用,应评估是否需选用薄膜或金属膜产品。
0402WGF6803TCE 采用厚膜工艺并设计用于工业级温度范围,适合多种温湿度及热循环工况。常见可靠性评估应包括温度循环、湿热(加速老化)、焊接热冲击与终端强度测试。具体的寿命与加速试验数据(如高温储存、寿命试验小时数)请以 UNI-ROYAL 官方规格书为准,以获得合规的可靠性证明。
如需详细的机械尺寸、回流焊温度曲线、耐久性测试数据或具体的订货代码与最小起订量,请告知,我可根据 UNI-ROYAL 官方资料为您获取或整理进一步的技术资料。

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.
