C1812X102K202T是禾伸堂(IHHEC) 推出的高压贴片多层陶瓷电容(MLCC),型号各部分含义清晰:
该产品针对中高压电子电路设计,兼顾小体积与高压耐受能力。
标称容值1nF(1000pF),容值偏差严格控制在**±10%** 以内,满足常规电路对容值一致性的要求,无需额外校准。
直流额定电压2kV,可承受短期脉冲过压(≤2.5kV),适合高压环境下的滤波、耦合等场景,避免过压击穿风险。
采用X7R铁电陶瓷介质,工作温度范围为**-55℃至+125℃**,温度变化范围内容值波动≤±15%——既优于Y5V等低成本介质的温度稳定性,又比NP0介质具有更高的容值密度,平衡了性能与成本。
1812贴片封装(无引线结构),尺寸紧凑(4.5mm×3.2mm×1.2mm典型厚度),兼容自动贴装(SMT)设备,可大幅提升PCB布局密度,适合小型化电子设备。
该产品凭借高压耐受、宽温稳定、小体积特性,广泛应用于:

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.
