201007J0100T4E 产品概述
一、产品简介
201007J0100T4E 是UNI-ROYAL（厚声）品牌的一款厚膜贴片电阻，封装为2010（国际尺寸标注，常见为2.0mm×1.25mm），标称阻值10Ω，精度±5%，额定功率750mW。器件适用温度范围为-55℃至+155℃，温度系数（TCR）为±200ppm/℃，额定工作电压为200V（最高允许器件两端的耐压指标）。
二、主要技术参数
- 阻值：10Ω
- 精度：±5%
- 额定功率：750mW（参考环境温度下）
- 额定工作电压：200V
- 温度系数：±200ppm/℃
- 工作温度范围：-55℃ ~ +155℃
- 封装：2010（贴片）
三、关键性能说明
- 厚膜工艺：抗冲击能力强、成本低、适合大批量应用。
- 功率与封装：在2010封装中提供750mW的额定功率，适合中等功率的贴片电路。
- TCR 与稳定性：±200ppm/℃ 表明温度变化时阻值波动可控，适用于对温漂要求不高的电路。
- 电压与功率限制需区分：虽然器件标称工作电压200V，但因功率限制，跨阻器件上的安全电压受P=V^2/R限制。对于10Ω、750mW的条件，连续直流最大允许电压约为 sqrt(0.75W×10Ω) ≈ 2.74V；超过此电压将导致过功率损耗直至损坏。200V为器件耐压能力，不等同于可在阻值两端长期施加的电压。
四、典型应用场景
- 板级负载电阻、分流/限流、放电（阻容放电）电阻
- 电源滤波、阻抗匹配、阻尼网络、测试校准中的负载元件
- 工业控制与家电中对成本敏感且功耗中等的场合
五、选型与使用建议
- 若应用为电流取样或需要高精度阻值建议选用低阻值与高精度（金属膜或专用电流感应电阻）。
- 设计时应按工作环境对额定功率进行热降额处理，参考厂商热降额曲线并预留裕度。
- 对于脉冲功率，应参考脉冲功率数据并验证热冲击能力。
- 贴装采用标准SMT回流工艺，推荐按厂商回流曲线控制峰值温度和时间以保证焊接可靠性。
六、可靠性与包装
常见为卷带（Tape & Reel）包装，便于SMT贴装和自动化生产。厚膜结构在振动与机械冲击下表现良好，但在高温长期应力下需关注阻值漂移与寿命衰减，建议参考完整的数据手册做可靠性评估。
七、总结
201007J0100T4E 是一款面向通用电路的厚膜贴片电阻，提供2010封装下较高的额定功率和宽温度适应性，适合中等功耗、对成本敏感且对精度要求不高的应用场景。选型时务必注意功率与电压的区别以及热降额要求，必要时参考厂商详细规格书或进行样片验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
