RC-02K2000FT 是风华(FH)系列的一款贴片厚膜电阻,封装为 0402(约 1.0 × 0.5 mm),阻值 200 Ω,精度 ±1%,额定功率 62.5 mW(1/16W),工作电压标称 50 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该款电阻以体积小、精度高、成本适中为特点,适合对体积与精度有一定要求的表面贴装电路。
补充说明:按功率限制计算,在不超过额定功率的条件下,该阻值对应的最大允许电压约为 sqrt(P·R) = sqrt(0.0625×200) ≈ 3.54 V。因此在电路设计时既要考虑器件标称耐压,也要以功率限制为准以免过载。
风华作为知名被动元件厂商,对材料与批次均有严格把控。厚膜工艺在环境与机械应力下具备良好的稳定性,但与薄膜相比在极端精密应用上温漂与噪声表现略逊。建议在关键产品中做样件老化、温循环及焊接可靠性验证,以确认在目标应用工况下的长期性能。
RC-02K2000FT 常见以卷带(Tape & Reel)方式供货,便于贴片生产线直接取料。采购时建议确认:工作批次、是否含任何特殊认证(如客户指定的可靠性测试报告)、交货规格(卷长、卷数)以及是否需要先行样件验证。对于量产项目,建议与供应链协同进行可靠性试验与来料检验标准定义。
RC-02K2000FT(FH 风华,0402,200 Ω,±1%,62.5 mW,±100 ppm/℃)以小尺寸与中高精度为主要优势,适合高密度电子产品中对空间和精度都有要求的应用。设计时需关注功率降额与实际电压限制,做好焊接与热管理,从而发挥该器件的最佳性能与长期可靠性。若需更详细的回流曲线、材料表或可靠性试验数据,可联系供应商获取完整规格书与认证资料。

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.
