0603WAF2204T5E 产品概述

一、产品简介

0603WAF2204T5E 为 UNI-ROYAL(厚声)品牌的厚膜贴片电阻器,封装为 0603(公制 1608,尺寸约 1.6 × 0.8 mm)。标称阻值 2.2 MΩ(四位代码 2204),精度 ±1%,额定功率 100 mW,最大工作电压 75 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55 ℃ 至 +155 ℃。该器件针对高阻值、面积受限的 SMT 应用而设计,适合批量贴装生产。

二、主要技术参数

  • 阻值:2.2 MΩ(2204)
  • 精度:±1%
  • 功率:100 mW(额定值,通常在 25 ℃ 环境下测定)
  • 工作电压:75 V(最大直流工作电压)
  • 温度系数:±100 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 类型:厚膜电阻(SMD)
  • 封装:0603(1608 公制)
  • 品牌:UNI-ROYAL(厚声)

三、性能特点

  • 高阻值、窄精度:2.2 MΩ 与 ±1% 精度适用于要求偏置稳定的高阻通道。
  • 宽温度范围与良好稳定性:-55 ℃ 至 +155 ℃ 的耐温能力满足多数工业和消费类环境。
  • 良好的批量贴装兼容性:0603 小尺寸适合空间受限的电路板设计。
  • 标准厚膜特性:成本效益高、工艺成熟,满足一般电子产品的电性能需求。
  • 低功耗电阻:在高阻值下实际通过的电流和功耗很小,适用于偏置、漏电限制与高阻输入电路。

四、典型应用

  • 高输入阻抗放大器与 ADC 输入端的偏置/上拉电阻
  • 传感器前端、静电保护电路与滤波网络中的高阻网络
  • 仪器仪表、计量设备及便携终端中对体积与阻值要求较高的场合
  • 低功耗电路中的漏电控制与时间常数设定(与大电容配合形成长时间常数)

五、PCB 布局与焊接建议

  • 推荐按 IPC/JEDEC 通用 0603 阵列布局设计焊盘,确保焊点可靠性与可重复贴装。
  • 兼容常见无铅回流焊工艺;具体回流曲线建议参照厂家提供的焊接说明书以避免超温。
  • 额定功率 100 mW 为 25 ℃ 条件下值,若工作环境温度升高,应参考厂方的降额曲线进行设计(高温下须降额使用)。
  • 对于高阻值电阻,注意清洗与残留物可能引入漏电路径,必要时采用低离子清洗或保护涂层。

六、存储与可靠性注意

  • 建议在干燥、常温环境(避免强光及腐蚀性气体)下存放,防潮防尘。
  • 若元件超过厂家建议的吸湿时间或包装已打开较久,回流焊前可按建议进行干燥处理以保证焊接质量。
  • 厚膜电阻通常具有良好的长期稳定性,但建议在关键应用中进行老化与可靠性验证。

七、型号说明与采购建议

  • 型号示例:0603WAF2204T5E(含义可理解为:0603 封装、WAF 系列、阻值 2204→2.2 MΩ,后缀表示包装/容差等信息)。
  • 选型时请确认实际应用的最大工作电压、环境温度与长期漂移要求;如需更低 TCR 或更高可靠性等级,请与供应商确认是否有特定系列或测试报告支持。

本产品适用于对体积、阻值与成本有平衡要求的高阻 SMT 应用。选购与设计中如需更详细的回流焊曲线、降额曲线或可靠性测试数据,请向 UNI-ROYAL 厂家或授权经销商索取完整规格书与测试报告。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
