EPSON(爱普生)Q22FA12800230是一款专为通用电子设备设计的26MHz无源贴片晶振,采用SMD2016-4P小封装,兼顾频率稳定性、宽温适应性与成本效益,广泛应用于消费电子、工业控制及通信等领域。以下从核心特性、参数解析、应用场景等维度展开概述。
该晶振属于EPSON无源晶振系列中的通用高频型号,核心定位为低成本、高可靠性的时钟基准源,无需额外驱动电路即可工作,核心特性包括:
各核心参数直接决定晶振的适用场景,具体解析如下:
26MHz是电子设备中通用高频基准频率,广泛适配MCU(如STM32系列)、蓝牙模块(BLE)、WiFi模块(早期802.11n)等的时钟输入,无需额外分频/倍频即可满足核心电路需求。
常温下频率偏差为±10ppm,换算为实际偏差值为26MHz×10⁻⁶=260Hz,该精度可满足:
无源晶振需外接10pF负载电容(通常并联在晶振两端与MCU引脚之间)才能达到标称26MHz频率,电路设计时需注意电容值匹配(误差建议≤±5%),避免因负载电容偏差导致频率漂移。
等效串联电阻是衡量晶振起振能力的核心指标,ESR越低,晶振越容易起振且稳定性越好。60Ω的ESR可适配多数MCU的内置振荡器电路(通常要求ESR≤100Ω),降低电路设计门槛。
该温度范围属于工业级标准,可覆盖:
SMD2016-4P封装为4脚无引脚贴片结构,优势包括:
EPSON作为晶振领域的老牌厂商,Q22FA12800230具备:
EPSON晶振以一致性好、产能稳定著称,Q22FA12800230已在全球范围内获得广泛应用,客户反馈其起振可靠、频率漂移小,是通用场景下的高性价比选择。
EPSON Q22FA12800230无源贴片晶振凭借26MHz通用频率、±10ppm常温精度、-40℃~+85℃宽温范围及SMD2016小封装,成为消费电子、工业控制等领域的理想时钟基准源,兼顾成本效益与可靠性,适合批量应用于对空间、精度有常规要求的电子设备。

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.
