0805W8F680JT5E 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,标称阻值 68Ω,阻值精度 ±1%,额定功率 125mW,适用于空间受限且对精度有中高要求的表面贴装电路。该器件在宽温度范围内保持稳定的阻值特性,适配常见电子制造流程。
该型号具有良好的阻值稳定性与制造一致性,TCR 在 ±200 ppm/℃ 范围内,适合一般信号与偏置网络应用。厚膜工艺使其抗浪涌和机械应力能力较好,经过常规环境与寿命试验后性能可靠。采用适配 SMT 的终端处理,兼容无铅回流焊工艺。
0805 封装尺寸小巧,便于高密度贴装与自动化生产。常规为卷带(Tape & Reel)包装,便于 SMT 贴装机取放。焊盘设计与推荐铺铜应参考厂商资料,以确保焊点可靠性与热循环性能。
适用于便携消费电子、通信设备、工业控制、信号调理与功率分配等场景,常用作限流、偏置、阻抗匹配与分压等位置。因额定功率和工作电压的限制,不适合高功率或高压直流主回路。
兼容主流无铅回流曲线(详见生产厂商的回流温度限制),建议遵循 IPC/JEDEC 等焊接规范以避免过热导致阻值漂移。储存环境建议干燥、无腐蚀性气体,并在建议的保质期内使用以保证贴装可靠性。
选用时应确认额定功率在实际工作温度下的退让(derating)曲线及最大工作电压边界,评估浪涌电流和长期负载寿命。对温漂、噪声或精度有更严格要求的场合,可考虑薄膜或金属膜高精度替代件。最终设计应以厂方完整规格书和可靠性数据为准。

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.
