- 最高工作电压：75V
- 温度系数：±100ppm/℃
- 封装：0603（英制）
- 材料类型：厚膜电阻
- 工作温度：-55℃ ~ +155℃
三、产品特性
- 精度高：±1% 满足精密分压、偏置与滤波电路需求。
- 小型化：0603 封装适用于高密度贴片电路板，节省空间。
- 宽温度范围与稳定性：-55℃~+155℃ 的适用范围保证在恶劣环境下仍能稳定工作。
- 良好的耐压能力：75V 额定电压适应中等电压偏置与测量应用。
- 温漂可控：±100ppm/℃ 的 TCR 适合多数模拟与数字电路要求。
四、典型应用场景
- 电路偏置与高阻分压网络（如传感器输入、滤波器）。
- 电源监测、上拉/下拉电阻与静态偏置电路。
- 便携设备、消费电子、物联网模块及仪器仪表中对小体积高阻值电阻的需求。
- 高阻抗测量前端、采样与隔离电路。
五、焊接与使用建议
- 推荐采用无铅回流焊工艺，按PCB制造商与工艺规范控制回流曲线，避免超温和长时间保温。
- 使用时注意功率与温度的降额：在高环境温度下应按厂商降额曲线计算允许功率，避免自热导致阻值漂移。
- 测量阻值时应使用较小测量电流，以减少自热误差（尤其对高阻值器件）。
- 装配时避免过大的机械压力与弯曲，以防封装或电极层剥离。
六、可靠性与测试
产品通过常规的可靠性测试，包括高温存储、温度循环、负载寿命、焊接可靠性与抗湿热测试等，以保证在规定环境与应力下具有稳定的电气性能与寿命表现。出厂前进行阻值、精度与外观检验。
七、选型与订购提示
型号 0603WAF3303T5E 指明了封装、系列与阻值精度特性。选型时请确认电路的最大工作电压、环境温度与允许功耗，必要时选择更高额定功率或更低温漂的型号以获得更好的可靠性与精度长期表现。如需批量采购或了解包装（卷带）与可得性，请通过供应渠道联系UNI-ROYAL（厚声）或授权分销商。

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.
