0805W8F2702T5E 产品概述
一、产品简介
0805W8F2702T5E 为 UNI-ROYAL（厚声）品牌的厚膜贴片电阻，采用 0805（2012公制，约2.0 mm × 1.25 mm）封装，阻值 27 kΩ，精度 ±1%，额定功率 125 mW。工作电压最高 150 V，温度系数 ±100 ppm/℃，工作温度范围 -55 ℃ 至 +155 ℃，适合多种中高密度贴片电路的精确限流、分压与偏置场合。
二、主要电气参数
- 电阻类型：厚膜电阻（SMD）
- 阻值：27 kΩ（标称）
- 精度：±1%（1% 公差）
- 额定功率：125 mW（参考值，实际可用功率受 PCB 散热与环境影响）
- 最大工作电压：150 V
- 温度系数（TCR）：±100 ppm/℃
- 工作温度范围：-55 ℃ ~ +155 ℃
三、性能特点
- 高精度：±1% 精度满足多数模拟与数字电路对阻值精确度的要求。
- 宽温区稳定性：-55 ℃至+155 ℃ 的工作范围适用于工业级环境。
- 良好可靠性：厚膜工艺提供稳定的长期阻值漂移特性。
- 适配SMT工艺：封装尺寸符合 0805 标准，兼容常见贴片与回流焊工艺，便于自动化生产。
四、典型应用场景
- 消费电子：电源分压、偏置网络、滤波电路。
- 仪器仪表：精密测量电路中作限流与分压元件。
- 通信设备：终端阻抗匹配与偏置网络。
- 工业控制：在耐高温或宽温度场景下的通用阻值元件。
五、使用与装配建议
- 降额使用：在高温或散热条件受限的 PCB 上，应对额定功率进行降额设计以保证长期可靠性。
- 电压考虑：工作电压不得超过 150 V，且注意在高阻值下的表面泄漏与绝缘间隙。
- 焊接兼容：兼容常见回流焊曲线，焊接前请参考供应商的焊接与可靠性规范。
- 布局注意：阻值受 PCB 热阻影响，尽量留有合理热扩散路径，避免热聚集。
六、命名说明与包装
- 型号解读：0805 表示封装规格，2702 可表示阻值编码（27 kΩ）；后缀常用于序列、包装形式或工艺代码，具体请参见厂商产品说明书。
- 包装方式：通常以卷带（Tape & Reel）方式供货，适合贴片生产线自动上料。

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.
