MR04X1000FTL是华新科(Walsin)推出的通用型表面贴装厚膜电阻,聚焦小体积、高精度、低功耗场景的电路设计需求。该电阻采用0402封装,以100Ω为标准阻值,搭配±1%精度、100mW额定功率,兼顾性能稳定性与成本经济性,是消费电子、工业控制等领域的常用基础元器件。
标称阻值100Ω,精度±1%,可满足大多数信号调理、分压、限流电路对阻值偏差的要求——例如传感器信号放大电路中,避免因阻值偏差导致放大倍数波动(偏差≤1%可保证信号传输一致性)。
温度系数±100ppm/℃,意味着温度每变化1℃,阻值变化±0.01Ω。在-55℃至+155℃的宽温范围内,最大阻值变化约±2.1Ω,满足宽温环境下的阻值稳定性需求(如户外设备、工业现场的极端温度场景)。
采用0402封装(英制0.04″×0.02″,公制1005,实际尺寸约1.0mm×0.5mm×0.3mm),具备以下优势:
华新科作为全球知名被动元器件制造商,拥有超过30年的生产经验,产品通过ISO9001质量管理体系、ISO/TS16949汽车行业认证。MR04X系列电阻广泛应用于华为、小米、苹果等知名厂商的供应链中,批次一致性好,可有效降低电子厂商的供应链风险。
该产品以平衡的性能、可靠的品质,成为小体积低功耗电路设计的优选基础元器件。

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.
