1206W4J0182T5E 厚膜贴片电阻产品概述

一、产品基本定位

1206W4J0182T5E是UNI-ROYAL(厚声) 推出的通用型厚膜贴片电阻,属于1206封装规格中的常规功率型号,核心面向对精度要求适中、成本敏感的电子电路设计,可覆盖工业、消费电子等领域的限流、分压、信号调理等基础需求。

二、核心电气参数详解

该电阻的关键性能参数明确,适配主流电路设计要求:

(1)阻值与精度

标称阻值为1.8kΩ(1800Ω),采用行业通用三位数字标识法(182)——前两位有效数字“18”乘以10的“2”次方(18×10²=1800Ω)。精度等级为**±5%(J级)**,适合对阻值偏差要求不苛刻的场景,若需更高精度需切换至F级(±1%)型号。

(2)功率与电压承载

  • 额定功率:250mW(1/4W),25℃环境下可稳定承载该功率;温度超过100℃时需按厚声规格书降额(如155℃时降额至约100mW),避免过热损坏。
  • 最大工作电压:200V,电路中该电阻两端直流/交流电压不得超过200V,否则可能击穿。

(3)温度系数与温漂

温度系数(TCR)为**±100ppm/℃**,表示温度每变化1℃,阻值变化±100×10⁻⁶。例如25℃→125℃(变化100℃),阻值最大漂移±1%,可满足一般温度波动场景(如室内电子设备),对温漂敏感需选低TCR(±50ppm/℃及以下)型号。

三、封装与物理特性

(1)封装规格

采用1206封装(英制),对应公制3216,物理尺寸为:长3.2mm±0.2mm、宽1.6mm±0.15mm、厚0.55mm±0.05mm。贴片式设计适配SMT自动化生产,占用PCB面积小,适合高密度电路布局。

(2)工艺与端电极

  • 工艺:厚膜工艺,通过丝网印刷电阻浆料于氧化铝陶瓷基片,高温烧结形成稳定电阻膜,成本低且性能可靠。
  • 端电极:三层结构(镍/锡或镍/银/锡),焊接性优异,兼容铅锡焊(Sn63Pb37)与无铅焊(Sn96.5Ag3Cu0.5),符合RoHS环保要求(无铅、无镉、无汞)。

四、典型应用场景

该电阻因成本适中、性能稳定,广泛应用于:

  1. 消费电子:手机、平板、小家电(电饭煲、微波炉)的辅助电路(电源分压、按键限流);
  2. 工业控制:低精度传感器信号调理、继电器驱动电路的限流元件;
  3. 电源电路:线性电源反馈分压、开关电源辅助限流网络;
  4. 通信设备:简单信号衰减、滤波电路(非射频核心部分)。

五、可靠性与环境适应性

(1)工作温度范围

覆盖**-55℃~+155℃**,达到工业级标准,可适应户外低温、高温车间等环境(高温时需功率降额)。

(2)长期稳定性

1000小时高温老化(125℃)后阻值漂移≤±0.5%,端电极焊接强度符合J-STD-020标准,可通过回流焊、波峰焊,焊接后性能无明显衰减。

(3)抗脉冲能力

短时间(10秒)可承受2倍额定功率的脉冲,适合简单脉冲电路(如LED驱动瞬时限流)。

六、品牌与品质保障

UNI-ROYAL(厚声)是国内电阻行业知名制造商,产品通过ISO9001、ISO/TS16949汽车级认证,1206W4J0182T5E批量一致性好、供货稳定,可提供完整规格书与技术支持,满足不同客户生产需求。

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
