KTR03EZPF1004 为 ROHM(罗姆)出品的贴片厚膜固定电阻,封装为 0603(美制),阻值 1MΩ,阻值精度 ±1%,额定功率 100mW,温度系数(TCR)典型为 ±100ppm/℃,工作温度范围 -55℃ 至 +155℃。该型号面向需兼顾体积、成本与中等温度稳定性的高阻值通用场合。
ROHM 产品线在批量一致性和可靠性上有较好控制。厚膜工艺在长期漂移、电阻分布和成本上具有优势,但相对薄膜产品在噪声、TCR、VCR 方面不占优。设计时应结合系统精度要求选择是否采用此类元件。
在实际采购与替换时,确认包装带卷、湿敏等级(MSL)、批号及 ROHM 规格书的最新版本。对于高压或极低漂移的应用,建议与薄膜或金属膜电阻进行对比验证。
总结:KTR03EZPF1004 为一款面向通用电子应用的 0603 厚膜高阻值元件,兼具成本与性能平衡,适合大多数对阻值精度和中等温度稳定性有要求的布局,但在高压、极低噪声或极高稳定性场合应谨慎评估或选用更高性能的薄膜器件。

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.
