0201WMJ0562TEE 是 UNI-ROYAL(厚声)推出的一款超小型贴片厚膜电阻,规格为 5.6kΩ ±5%,功率额定 50mW,最大工作电压 25V,温度系数(TCR)±200ppm/℃,工作温度范围 -55℃ 至 +155℃。封装为 0201(超小型 SMD),适合对占板面积和重量有严格限制的现代电子产品。
TCR ±200ppm/℃ 表明温度上升会引起阻值随之变化,例如从 25℃ 升高到 125℃(ΔT=100℃)时,阻值可能变化约 2%(200ppm×100℃ = 20000ppm = 2%)。与初始 ±5% 公差叠加,长期或高温运行下的阻值偏差需在电路设计中预留余量。
0201 超小封装适合自动化贴装与回流焊工艺,但对贴装精度、焊膏印刷与回流曲线要求较高。器件尺寸较小,通常不做表面标记,采购与库房管理需用料号和条码识别。建议采用 tape‑and‑reel 包装以提高贴装效率;回流工艺请参照厂方推荐温度曲线,并注意清洗残留焊剂以避免长期可靠性问题。
若需更高精度或更低 TCR,可考虑金属膜或薄膜精密电阻;若需更大功率,应选择更大封装或专用功率电阻。0201WMJ0562TEE 适用于体积受限且为一般公差、一般稳定性需求的低功耗场合,是成本与体积优化的常用选型。

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.
