201007J039JT4E 是由 UniOhm(台湾厚声)出品的一款高可靠性片式厚膜电阻,封装为 2010(公制 2.0 × 1.25 mm,常见对应英制 0805)。该型号阻值 3.9Ω,精度 ±5%(J),额定功率 0.75W(3/4W),额定工作电压 200V,温度系数(TCR)±200ppm/℃,工作温度范围为 -55℃ 至 +155℃,适用于对功耗、耐压及热稳定性有中等要求的应用场合。
UniOhm 厚声采用成熟厚膜制程并通过常规的热循环、湿热及焊接可靠性测试,适合大批量工业制造使用。对于关键或特殊环境应用,建议向供应商索取具体的可靠性报告与测试数据以便评估。
若需更高精度或更低 TCR,可考虑薄膜或低温漂厚膜产品(如 ±1% 或 ±50ppm/℃ 等级);若单元功耗需求高于 0.75W,建议选用更大封装(1206/2010 以上功率等级更高的型号或功率电阻)。
如需详细的降额曲线、焊接参数或可靠性测试报告,可联系供应商索取 Datasheet 与相关认证文件。

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.
