- 温度系数（TCR）：±100ppm/℃
- 工作温度范围：-55℃ ~ +155℃
- 封装：0603（1608 公制）
三、优势特点
- 精度高：±1% 公差满足阻值精准度要求，便于用于分压、阻抗匹配和精密滤波电路。
- 小型化：0603 封装利于高密度 SMT 布局，节省 PCB 面积，适配便携式与微型化设计。
- 宽温度适应性：-55℃ ~ +155℃ 的工作温域，适合多温度环境应用。
- 品牌与质量保障：UniOhm 台湾厚声在厚膜电阻领域具有成熟制程与稳定品质控制。
四、典型应用场景
- 精密分压器与阻抗匹配网络
- 便携消费电子、可穿戴设备电源与测量模块
- 工业控制与仪表的传感器接口、滤波电路
- 通信设备、测试测量仪器中的低功耗网络
五、封装与焊接建议
- 兼容标准 SMT 回流焊工艺，建议回流峰值温度 ≤ 260℃ 且遵循焊膏与 PCB 的工艺规范。
- 为保障长期可靠性，拼板与贴装时避免过度机械应力，回流后静置冷却避免热冲击。
- 在高温环境或接近额定功率工作时，应考虑功率降额与散热设计，保证组件在安全工作点内运行。
六、使用与选型注意事项
- 虽按功率计算的理论电压可能高于工作电压限制，但产品的最大工作电压以 75V 为准，超出可能导致击穿或失效。
- 对温漂敏感的场合应评估 ±100ppm/℃ 的影响，必要时选择更低 TCR 的产品或采用匹配补偿措施。
- 如需获得批量可靠性数据（如负载寿命、湿热抗性、温度循环等），建议索取 UniOhm 的详细数据手册与可靠性报告。
七、资料与采购建议
欲获得完整规格书、回流曲线、可靠性试验数据或样品，请联系 UniOhm 官方渠道或授权分销商，确认具体封装代码与包装数量（卷装、带盘等），以便于生产导入与质量追溯。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
