25121WF100KT4E 产品概述
一、产品简介
25121WF100KT4E 为 UNI-ROYAL（厚声）系列贴片厚膜电阻，封装规格为 2512（约 6.35 × 3.2 mm），额定功率 1W，阻值 1Ω，公差 ±1%。该器件采用厚膜工艺制成，适用于需要中等功率耗散与稳健机械强度的表贴场合，工作温度范围宽（-55℃ ~ +155℃），适应工业级环境。
二、主要参数
- 类型：厚膜贴片电阻（SMD）
- 封装：2512
- 阻值：1Ω
- 精度：±1%
- 额定功率：1W
- 最大工作电压：200V
- 温度系数（TCR）：±200 ppm/℃
- 工作温度：-55℃ ~ +155℃
三、性能特点
- 阻值精度高、稳定性良好，适合要求 ±1% 的电路设计；
- TCR ±200 ppm/℃ 在常温至高温范围内具有可控温漂；
- 2512 封装提供较好的功率耗散能力与机械强度，适合波峰/回流焊工艺；
- 额定电压 200V，适配较高电压场合的能量分配需求。
四、典型应用
- 电源管理与分压/分流（如电流取样、限流）；
- 工业控制与自动化设备；
- LED 驱动与配电模块；
- 测量仪器与信号调理电路；
- 一般电子设备的功率耗散场景。
五、安装与使用建议
- 推荐采用卷带（Tape & Reel）进行 SMT 贴装；回流焊时遵循元件和焊料的推荐曲线，峰值温度建议控制在 ≤260℃ 并缩短高温暴露时间；
- 在高温环境下应对额定功率进行降额处理，具体降额曲线应参考厂方数据手册；
- 焊接后避免剧烈机械应力及长时间超温工作，以保持阻值稳定性。
六、包装与品质保障
常见包装形式为卷带供 SMT 生产线直接使用。UNI-ROYAL 出厂前通常对阻值、公差、外观和焊接性进行检测。具体可靠性（温度循环、负载寿命等）和认证信息，请以厂方数据手册与检验报告为准。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
