LTR18EZPJ112 产品概述
一、概述与主要参数
LTR18EZPJ112 是 ROHM（罗姆）生产的厚膜贴片电阻，封装为 0612（公制 1632，约 1.6 mm × 3.2 mm）。标称阻值 1.1 kΩ，允许偏差 ±5%，额定功率 750 mW，温度系数（TCR）为 ±200 ppm/℃，工作温度范围为 -55℃ 至 +155℃。作为厚膜工艺元件，该系列以成本效益高、通用性强为特点，适合大批量通用电子设备设计使用。
二、特性与优势
- 高性价比：厚膜制造工艺适合大规模生产，单片成本低，适用于常规分压、限流、拉/下拉等用途。
- 中等功率能力：0612 封装提供 750 mW 的额定功率，适用于比 0402/0603 更高功耗但又不需大功率电阻的场合。
- 宽温度工作范围：-55℃ 至 +155℃，可满足工业级环境下的长期工作要求。
- 常规稳定性：TCR ±200 ppm/℃ 与 ±5% 精度组合满足多数模拟与数字电路对温漂和阻值稳定性的基本需求。
三、典型应用场景
- 消费电子：电源分流、偏置网络、限流元件等；
- 工业控制设备：传感器信号调理、接口电路等；
- 通信及网络设备：终端电阻、阻抗匹配、偏置网络；
- 一般电子模组的通用阻值需求。
四、设计与选型建议
- 功率余量：在实际电路中应保留余量，参考 ROHM 数据手册中给出的温度升高与功率降额曲线，避免长期满载工作；
- 温漂与精度：若对温度稳定性或精度要求更严格，请考虑更低 TCR 或更高精度（±1%、±0.1%）的电阻类型；
- 封装热管理：0612 封装热阻较小，但仍建议合理 PCB 散热设计（增大焊盘、铜箔面积）以利于功率耗散；
- 可焊性与回流：遵循制造商推荐的回流曲线进行焊接，避免超出温度峰值和时间导致性能退化。
五、可靠性与注意事项
- 长期湿度与热循环可能导致阻值漂移，应在关键或高可靠性场合做相应验证；
- 避免机械应力（弯曲、冲击）集中在焊点处，贴片电阻易因应力产生表面裂纹或失效；
- 若需用于汽车或更严苛环境，确认具体产品是否具备相应认证（如 AEC-Q）再行选型。

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.
