RTT029310FTH是台湾旺诠(RALEC)推出的0402封装厚膜贴片电阻,针对小型化、低功耗电子电路的高密度贴装需求设计,兼具成本优势与可靠性能,核心参数覆盖阻值、精度、功率等关键指标,广泛适配多领域应用场景。
该电阻属于旺诠厚膜电阻系列的常规精度型号,主打「小体积+稳定性能」平衡:
阻值固定为931Ω,精度±1%,允许阻值范围为921.69Ω~940.31Ω,满足大多数信号调理、分压、滤波电路的精度需求(无需高精度薄膜电阻的场景)。
温度系数±100ppm/℃,意味着温度每变化1℃,阻值变化±0.0931Ω。在工作温度范围(-55℃~+155℃)内,总阻值变化最大约±19.55Ω,满足工业级环境下的基本温度稳定性要求。
封装尺寸符合IPC标准(0.04英寸×0.02英寸),兼容主流贴装设备(富士、西门子等),焊接可靠性高(可通过回流焊、波峰焊实现批量贴装,具体工艺需参考旺诠官方datasheet)。
采用旺诠成熟的厚膜制造工艺:
RTT029310FTH通过平衡性能与成本,成为小型化电子设备的实用电阻选型,可满足多领域的常规电路需求。

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.
