0402WGF1371TCE 是 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装尺寸为 0402(公制 1005),标称阻值 1.37 kΩ,精度 ±1%,额定功率 62.5 mW(即 1/16 W),最大工作电压 50 V,温度系数(TCR)典型 ±100 ppm/°C,工作温度范围 -55 ℃ ~ +155 ℃。该系列产品结合小型化体积与稳定的电气性能,适合对空间和精度有一定要求的消费电子、通讯设备和工业控制类电子产品。
0402 尺寸的厚膜电阻因体积限制,额定功率相对较低(62.5 mW),在实际电路设计中需考虑功率分配和散热条件。环境温度升高时应按制造商的功率降额曲线(derating curve)进行设计,避免在高温环境下长期满负荷运行导致失效。TCR ±100 ppm/°C 在温度变化较大场合表现为阻值随温度变化可控,适合多数通用电路;如对温漂要求更严苛,请优先考虑低 TCR 或金属膜、薄膜产品。
UNI-ROYAL 厚声系列电阻通常经过包括但不限于下列可靠性试验:焊接热(符合 J-STD-020)、温度循环、湿热(HAST/85/85 或 IEC 湿热测试)、机械震动与冲击以及负载寿命测试等。生产过程中实施严格的阻值筛选与老化控制,确保长期稳定性与批次一致性。具体测试参数和认证请参见厂商详细数据手册或向供应商索取检测报告。
该型号通常以带卷(tape & reel)形式供应,便于 SMT 自动贴装。订购时请确认包装单位(例如 3,000 或 10,000 颗/卷)、阻值批次号、需要的出厂测试单与可靠性报告。更多技术参数、尺寸图与推荐焊盘请参考 UNI-ROYAL 官方数据手册或向授权分销商咨询获取原厂资料。
如需我为该型号生成推荐 PCB 焊盘尺寸、回流焊曲线建议或与其它阻值/精度的比较选型表,可提供详细需求,我将进一步给出实用方案。

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.
