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。
该电阻的关键性能参数明确,适配主流电路设计要求:
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。
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。
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。
该电阻因成本适中、性能稳定,广泛应用于:
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)。
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。
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)。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
