核心参数汇总:
参数项 具体规格 容值 47nF(473) 精度 ±10%(K级) 额定电压 250VDC 温度系数 X7R(-55℃~+125℃,容值变化±15%) 封装 1206(表面贴装) 品牌 华新科(Walsin)该产品的核心优势围绕温度稳定性、封装适配性与电压容值匹配三个维度展开:
X7R是铁电陶瓷介质的典型温度系数,其核心特点是:在-55℃至+125℃的宽温度范围内,容值变化率控制在**±15%以内**。对比Y5V(+22%~-82%)等低稳定性介质,X7R能有效避免因温度波动导致滤波、耦合效果失效,适合对容值稳定性有要求的场景。
1206封装是SMT市场的主流规格,具备以下实用优势:
250VDC额定电压+47nF容值的组合,精准覆盖中高压小容量需求:既满足电源电路的中高压纹波抑制,又避免了大容量电容的体积冗余,平衡性能与成本。
结合性能特性,该电容适用于以下主流场景:
华新科作为全球前五大被动元器件厂商,该产品的可靠性经过严格验证:
该产品凭借稳定的性能、紧凑的封装与可靠的品牌保障,成为中高压小容量电路的优选元件,广泛适配工业、消费电子等领域的常规应用需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
