杭晶(HCI)3131M-32.768DTTLRRL是一款针对实时时钟(RTC)场景优化的工业级贴片晶振,凭借稳定的频率特性、小体积封装及宽温可靠性,广泛适配消费电子、工业控制、物联网等多领域设备。
该晶振以32.768kHz(RTC系统的标准基准频率,分频后可直接输出1Hz秒信号)为核心,主打高稳定性、低功耗、小体积三大核心价值,解决传统晶振在温湿度变化、振动环境下的频率漂移问题,同时满足小型化设备的空间集成需求。
宽温下的频率可靠性:
在-40℃至+85℃范围内,频率变化始终控制在±5ppm内,可确保工业传感器、户外物联网节点在极端温度下的计时精度,避免数据采集或控制指令的时间误差。
低损耗与低功耗适配:
70Ω的ESR值远低于部分竞品(部分竞品ESR达100Ω以上),减少晶振自身功率损耗;同时32.768kHz低频特性与低功耗RTC芯片(如PCF8563、DS3231)完美适配,可延长电池供电设备(智能手环、物联网节点)的续航时间。
小体积封装的灵活性:
SMD3215封装可轻松集成到智能手表、蓝牙耳机、小型传感器等紧凑设备中,无需牺牲其他功能模块的空间,满足当前电子设备小型化趋势。
杭晶的品控保障:
HCI作为国内晶振行业老牌厂商,3131M系列经过严格可靠性测试(高温高湿存储、振动冲击、回流焊兼容性测试),良品率达99.9%以上,供货周期稳定,适合批量生产需求。
该晶振的核心应用集中在需要稳定实时时钟的领域:
HCI 3131M-32.768DTTLRRL凭借工业级的温度稳定性、低损耗特性及小体积封装,成为RTC场景下的高性价比选择。无论是消费电子的小型化需求,还是工业设备的宽温可靠性要求,该晶振均能提供稳定可靠的时钟基准,适合各类量产项目的选型。

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.
