LTR18EZPJ200 为 ROHM(罗姆)公司系列的厚膜贴片电阻器,封装规格为 0612。标称阻值 20Ω,阻值精度 ±5%,额定功率 750mW,温度系数(TCR)±200ppm/℃,工作温度范围 -55℃ 至 +155℃。该器件以紧凑封装实现较高的功率承载能力,适用于对体积与散热有平衡要求的电路设计。
适用于消费类电子、通信设备、工业控制与电源管理等领域的限流、分压、阻尼、偏置网络等场景。由于具有 750mW 的功率等级,常用于功率相对集中的局部电路,例如 LED 驱动电阻、开关电源次级网络或电机驱动周边电路。若用于精密电流采样或车规关键回路,应评估精度与温漂是否满足要求并参考厂方同类高精度产品。
总体而言,LTR18EZPJ200 在尺寸与功率之间提供了良好的折衷,适合对体积和散热有中等要求的通用电路。实际应用时需重视 PCB 热设计与环境温度对额定功率的影响,必要时参考厂方完整规格和降额曲线以保证长期稳定性。

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.
