1210W2J0112T5E 产品概述

一、产品简介

1210W2J0112T5E 为 UniOhm(台湾厚声)出品的一款 1210 封装厚膜电阻,属于通用功率型贴片电阻系列。此型号阻值为 1.1 kΩ,公差 ±5%,额定功率 500 mW,工作电压 200 V,温度系数为 ±100 ppm/℃,适用工作温度范围为 -55℃ 到 +155℃。该产品兼容旧型号 1210W3J0112T5E,可以直接替代旧型号用于同类电路设计与生产。

二、主要参数

  • 电阻类型:厚膜电阻(Thick Film)
  • 封装尺寸:1210(Imperial 3216)
  • 阻值:1.1 kΩ
  • 精度(公差):±5%(J)
  • 额定功率:500 mW(在推荐环境温度和散热条件下允许的持续功率)
  • 最高工作电压:200 V
  • 温度系数(TCR):±100 ppm/℃(典型)
  • 工作温度范围:-55℃ ~ +155℃
  • 品牌:UniOhm(台湾厚声)
  • 兼容旧型号:1210W3J0112T5E

三、产品特性与优势

  • 稳定的电阻特性:采用成熟的厚膜工艺,抗冲击、耐湿热性能良好,适合一般电子消费类及工业类电路应用。
  • 宽温域适应性:-55℃ 到 +155℃ 的工作温度范围,能够满足较严苛环境下的使用需求。
  • 较高的功率承载:1210 封装在合理散热条件下可提供 500 mW 的额定功率,适合具有一定热量需求的分流或偏置电路。
  • 兼容性良好:机械尺寸和电气特性设计上与旧型号 1210W3J0112T5E 兼容,便于替换、升级以及库存整合。
  • 生产工艺成熟:适用于自动贴装和无铅回流焊工艺,良品率高,适合集成到量产流程。

四、典型应用场景

  • 电源与电源管理电路:限流、分压、偏置、电流检测等场合。
  • 家用电器与消费电子:电视、机顶盒、路由器等需要通用阻值与中等功率的电路。
  • 工业控制与仪表:在非极端高精度要求下的采样、分压与滤波电路。
  • 消耗型及保护应用:作为保险式限流、充电电路中非关键精度分流元件。

五、可靠性与使用建议

  • 环境适应:本型号对潮湿、振动有较好的耐受性,但建议在高湿或有腐蚀性气体的环境中采取封装或涂覆措施以延长可靠性。
  • 温升与降额:在高环境温度或散热不良的应用中,应按电路热设计对额定功率进行合理降额,避免长期过载导致电阻漂移或失效。
  • 焊接工艺:兼容常规无铅回流焊流程。建议遵循厂商的回流曲线与峰值温度限制,避免长时间高温暴露和重复回流。
  • 储存与搬运:避免潮气和强烈机械冲击,保持原厂防潮包装直至贴装前。

六、封装与订购信息

  • 封装:1210(3216 米制)
  • 卷带包装,适合自动贴装机使用。常见的订购单位为卷装(带卷)或小包装(根据客户需求)。
  • 订购时请注明完整型号:1210W2J0112T5E(UniOhm 台湾厚声),并可备注兼容旧型号 1210W3J0112T5E 以便对接旧库存或物料编号。

七、选型与替代考虑

选择 1210W2J0112T5E 时,若电路对精度与温漂有更高要求,可考虑更高精度(±1% 或 ±2%)或更低 TCR 的薄膜/金属膜电阻;若需要更高功率,则应选择更大封装或功率等级的电阻。替代时请核对最大工作电压、额定功率及温度系数,确保新元件在目标应用中满足长期可靠性要求。

如需进一步的完整电气曲线、回流焊曲线、可靠性测试报告或样品支持,可联系供应商或厂商技术支持获取详细数据与检验报告。

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
