ESR03EZPJ5R1 是 ROHM(罗姆)出品的一款厚膜贴片电阻,封装为 0603(1608 公制),标称阻值 5.1 Ω,额定功率 250 mW,阻值精度 ±5%,允许工作电压 150 V,温度系数为 ±200 ppm/℃,工作温度范围 -55 ℃ ~ +155 ℃。该型号定位为通用型表面贴装电阻,适用于空间受限的消费类与工业电子设备。
选择 ESR03EZPJ5R1 时应确认:所需阻值、精度与温漂是否满足电路误差预算;封装 0603 是否适配生产与维修工艺;额定功率与实际工作功耗是否匹配。若需要更高精度或更低温漂,可考虑薄膜或金属膜(或更高精度厚膜)替代;若功率需求高于 250 mW,应选用更大封装或专用功率电阻。
ESR03EZPJ5R1 是一款面向通用电子应用的成本效益型厚膜贴片电阻,适合在空间受限且对精度要求不极端苛刻的场合使用。其 0603 小尺寸和 250 mW 功率等级在消费电子、工业控制等领域具有良好的适配性。最终选型应结合电路功率、温度工作点以及精度需求,并按 ROHM 数据手册执行焊接与热管理规范以确保长期可靠性。

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.
