NCP03WB473F05RL 为 muRata(村田)系列微型 NTC 热敏电阻,标称阻值 47 kΩ(25℃),封装 0201(极小型)。该器件具有高精度电阻公差 ±1% 与 B 值(热敏常数)高稳定性(B 值精度 ±3%),适用于对体积、功耗和响应速度有严格要求的便携及消费类电子温度检测与补偿场景。
热敏电阻通常用指数关系描述:R(T) = R25 · exp[B · (1/T - 1/T25)](T 以开尔文计)。基于器件标称值,可估算常用温度点阻值(近似):
若设计中优先考虑极小封装及较高阻值(便于与高阻输入匹配)、并能接受中等测温精度与低功耗测量,NCP03WB473F05RL 为合适选择。对更高精度的温度测量,建议结合校准、使用参考电路或选择 B 值与阻值公差更严格的型号。
总结:NCP03WB473F05RL 在微型化、低功耗温度检测与补偿应用中具有明显优势,设计时关注自发热、热耦合和校准策略,可获得稳定且实用的温度测量性能。若需更详细的焊接规范或阻温曲线,请参考厂商技术资料或联系供货商获取原厂数据手册。

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.
