KTR10EZPF1003 是 ROHM(罗姆)旗下的一款贴片厚膜电阻,阻值 100 kΩ,精度 ±1%,功率额定值为 125 mW,适用温度范围为 -55 ℃ 到 +155 ℃。该器件以稳定的工艺与性价比著称,适合一般电子设备中对精度和耐温性能有一定要求的场合。
0805 封装(约 2.0 × 1.25 mm)是常用的中小尺寸 SMD 类型,便于高速贴片和回流焊装配。厚膜电阻结构使其具有良好的机械强度和焊接可靠性,兼容常规回流焊工艺,适合自动化贴装生产线。
温漂方面,TCR = ±100 ppm/℃ 相当于阻值随温度变化约 0.01%/℃(100 kΩ 时约 10 Ω/℃)。在完整温度区间(-55 ℃ 到 +155 ℃,跨度 210 ℃)理论温漂约为 210 × 100 ppm = 21000 ppm,即约 ±2.1%,与初始 ±1% 精度叠加后需在设计中一并考虑总体误差。
总结:KTR10EZPF1003 以其 100 kΩ 的通用阻值、±1% 的精度和宽温特性,适合多种工业与消费电子应用。在设计中应综合考虑功率降额、温漂及长期稳定性,以确保电路性能与可靠性。若需用于关键或特殊应用,建议查阅 ROHM 官方资料或联系技术支持获取更详细的可靠性与降额信息。

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.
