SFR18EZPJ111 产品概述
一、概述
SFR18EZPJ111 是 ROHM（罗姆）推出的一款厚膜硫化物耐受型贴片电阻（Sulfur Tolerant Chip Resistor），封装为 1206（公制 3216），阻值 110Ω，精度 ±5％，额定功率 0.25W，额定工作电压 200V。工作温度范围 -55℃ 至 +155℃，温度系数典型值 ±200ppm/℃。该系列针对含硫/腐蚀性环境进行了材料与工艺优化，适用于对硫化氢等硫化物敏感的应用场合。
二、主要性能与特点
- 厚膜结构，工艺成熟、成本效益高。
- 硫化物耐受处理，抗硫化环境能力优异，适合油田、工业、汽车等恶劣环境。
- 1206（3216）封装尺寸，有利于功率分散与焊接可靠性。
- 额定功率 0.25W，额定电压 200V，可用于中低功率、高电压场合的限流与分压。
- 温漂 ±200ppm/℃，在一般工业级温度范围内性能稳定。
三、电气与环境规格（要点）
- 阻值：110Ω ±5%
- 额定功率：0.25W（需按厂方曲线考虑环境温度与散热条件）
- 额定电压：200V（最大工作电压）
- 温度系数（TCR）：±200ppm/℃
- 工作温度：-55℃ ~ +155℃
- 封装：1206（3216mm）表面贴装
四、典型应用场景
- 汽车电子（车内/发动机舱需注意硫化物存在的部位）
- 工业控制、传感器接口、阀门控制等含硫环境下的电阻网络
- 电源输入滤波、限流、分压器及一般信号回路
- 能承受较高工作电压且要求可靠性的商业与工业设备
五、选型与使用注意事项
- 功率与环境温度：额定功率为特定环境与散热条件下的值，高温时应参考厂方功率降额曲线并留安全裕量。
- 焊接工艺：遵循 ROHM 推荐的回流温度曲线，避免长时间过高温度及机械应力，以免影响封装与电阻性能。
- 抗硫能力虽优，但仍建议在强腐蚀或化学暴露环境下进行封装保护或采用额外防护措施。
- 使用前请对比实际电路电压与额定电压，避免长期满压运行导致寿命下降。
六、可靠性与包装
该器件符合常见片式电阻的可靠性测试要求（温循、湿热、机械冲击等），并采用适合 SMT 贴装的卷带包装，便于自动化贴片生产。为确保长期稳定性与性能一致性，建议在设计初期参考 ROHM 完整器件数据手册与应用说明，进行必要的环境验证。

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.
