0402WGF4533TCE 产品概述
一、产品简介
0402WGF4533TCE 是 UNI-ROYAL（厚声）推出的一款高阻值厚膜贴片电阻，封装为0402（约1.0 × 0.5 mm）。阻值为 453 kΩ，精度 ±1%，额定功率 62.5 mW，额定工作电压 50 V，温度系数（TCR）±100 ppm/℃，工作温度范围 -55℃～+155℃。该器件针对高阻抗、体积受限且需一定温漂控制的表面贴装应用优化。
二、主要参数
- 阻值：453 kΩ（±1%）
- 类型：厚膜电阻（SMD）
- 封装：0402（公制约 1.0 × 0.5 mm）
- 额定功率：62.5 mW（常温参考）
- 额定工作电压：50 V（请勿超过此电压）
- 温度系数：±100 ppm/℃
- 工作温度：-55℃～+155℃
- 品牌：UNI-ROYAL（厚声）
三、性能与可靠性
该厚膜电阻采用成熟制程，具有良好的长期稳定性和抗环境影响能力。±1% 精度可满足精密偏置与分压需求；±100 ppm/℃ 的温度系数保证在温度变化条件下阻值变化受控。工作温度上限 155℃，适应宽温度工作环境。兼容无铅回流焊工艺，适用于常见的 SMT 贴装与回流流程。
四、典型应用场景
- 高输入阻抗的放大器输入与偏置网络
- 精密采样/分压电路、模数前端（ADC）输入保护/偏置
- 便携式与物联网终端中占板面积受限的电路
- 滤波、脉冲整形与高阻抗检测电路
五、使用与选型建议
- 虽然按功率计算允许的电压值较高，但器件标称工作电压为 50 V，应在电路设计中严格遵守以避免绝缘或端接失效。
- 在高温环境或长期连续工作条件下，应留有功率余量，避免接近额定功率长期运行。
- 推荐采用标准 SMT 回流曲线（兼容无铅回流），避免超温或过长热敲击。清洗时选择与厚膜兼容的清洗剂，避免强溶剂长期浸泡。
- 存储建议：干燥、常温、避免潮湿与强腐蚀性气体。开封后建议在规定时间内使用完毕（遵循锡膏和回流工艺管理）。
六、包装与选购
0402WGF4533TCE 通常以卷带（Tape & Reel）方式供应，便于自动贴片生产线使用。选型时请确认阻值、精度及工作电压满足电路需求；如用于高可靠或极端环境（如汽配等级），建议与供应商确认额外的测试报告或认证。若需大批量采购或定制参数，可联系 UNI-ROYAL 正式渠道获取更详尽的样品与技术支持。

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.
