0402WGF5102TCE 产品概述
一、产品简介
0402WGF5102TCE 为 UNI-ROYAL（厚声）系列的贴片厚膜电阻，封装尺寸为 0402（公制 1005/英制 0402）。标称阻值 51kΩ，精度 ±1%，适用于对体积与可靠性有较高要求的小型化电子产品。该器件以稳定的电阻值、良好的温度特性和广泛的工作温度范围为特点，适合批量表面贴装生产和自动化装配。
二、主要参数
- 电阻类型：厚膜电阻（贴片）
- 封装：0402
- 标称阻值：51kΩ
- 精度：±1%（±1% 表示高精度等级）
- 额定功率：62.5 mW（典型额定功率，基于 0402 尺寸）
- 额定工作电压：50 V
- 温度系数（TCR）：±100 ppm/℃
- 工作温度范围：-55℃ 至 +155℃
- 品牌：UNI-ROYAL（厚声）
三、特性与优势
- 小型化封装：0402 体积小、占板面积少，适合高密度布板与便携产品。
- 精度较高：±1% 满足多数精密分压、偏置与反馈网络的需求。
- 宽温区性能稳定：-55℃ 至 +155℃ 的工作温度保证在恶劣环境下仍能可靠工作。
- 良好温漂：±100 ppm/℃ 的 TCR 对一般精度电路影响较小，有利于温度敏感电路的稳定性。
- 兼容贴片工艺：适用于常规 SMT 自动贴装与回流焊流程，便于量产。
四、典型应用场景
- 手持与可穿戴设备中的分压与偏置网络。
- 消费类电子、通信终端与物联网模块的电阻矩阵。
- 工业控制与测量仪器中的参考和阻值网络（对中等精度要求场合）。
- 阻抗匹配、滤波网络与串联限流应用（需注意功率与电压限制）。
五、选型与使用注意
- 功率与降额：0402 的额定功率有限，实际使用中应考虑降额和 PCB 散热条件，避免长期在额定功率附近工作。
- 电压限制：不可超过 50V 的工作电压；若电路有高电压脉冲或瞬态，请选用更高电压等级或采取限压措施。
- 温度影响：TCR ±100 ppm/℃ 在宽温度变化时仍会带来阻值漂移，关键计量场合可考虑配套温度补偿或更低 TCR 的器件。
- 焊接工艺：兼容常见回流焊，但应遵循厂商建议的回流曲线与预热/冷却规范，以降低热应力与焊点缺陷。
六、可靠性与储存
- 存储建议：避免潮湿与腐蚀性气体，推荐相对湿度 < 60%，常温环境下密封保存。
- 可靠性测试：厚膜结构具有良好的振动与冲击耐受性，适合一般工业与消费级的机械环境。需关注长期功率应力下的阻值漂移，必要时进行寿命验证。
七、包装与采购提示
- 常见包装形式为卷带（Tape & Reel），便于 SMT 自动化贴装。
- 下单时请确认所需阻值、精度以及包装单位（卷长或每盘数量），并核对是否需 RoHS/无铅合规证书。
如需样品测试或更详细的回流焊曲线、可靠性测试数据与寿命评估报告，可联系供应商技术支持，以便在具体应用中获得最佳性能与可靠性保障。

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.
