FRC0402F3742TS 是 FOJAN(富捷)推出的一款贴片厚膜电阻,封装为 0402(约 1.0 mm × 0.5 mm),阻值 37.4 kΩ,精度 ±1%。该器件属于低功耗、微型化的 SMD 元件,设计用于要求体积小、稳定性好的表面贴装电路。典型型号标识为 FRC0402F3742TS,适合批量贴装与自动化生产。
说明:根据功率与阻值的物理关系,从功率上计算的理论最大允许电压为 V = sqrt(P·R) ≈ 48.3 V。产品标称工作电压为 50 V,实际使用时请以数据手册和电路热控条件为准,并在高温环境下进行功率降额。
FOJAN 厚膜电阻经过片上可靠性测试,能满足常见的温度循环、湿热和机械应力试验要求。TCR ±100 ppm/℃ 表明在温度变化时阻值变化可控;长期漂移主要受厚膜材料与封装工艺影响,建议在关键精度场合进行实际环境下的提前验证。若需更严格的可靠性保证或认证信息,请向供应商索取完整的检验报告与可靠性试验数据。
结语:FRC0402F3742TS 以其微小封装、良好精度与宽温特性,适用于对体积与稳定性有较高要求的电子产品设计。针对具体应用的热管理和电压降额建议在设计初期予以充分考虑,以确保长期稳定运行。若需完整数据手册或批量供货信息,请联系 FOJAN 或其授权代理。

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.
