HCI 3131M-32.768DT06LLL是一款专为实时时钟(RTC)计时、低功耗设备设计的小型贴片晶振,核心频率为行业通用的32.768kHz(即2¹⁵Hz,可通过简单分频得到1Hz秒信号)。其定位兼顾工业级稳定性与消费电子小型化需求,广泛应用于以下场景:
该晶振的核心参数针对计时类应用做了优化,关键指标如下:
SMD3215-2P封装尺寸仅3.2mm×1.5mm,比传统直插晶振体积缩小60%以上,可轻松嵌入智能手表、门锁等紧凑设备的PCB中,同时支持自动化SMT贴装,提升生产效率。
工作温度范围-40℃~+85℃,覆盖了我国南北地区的极端环境(如北方冬季低温、南方夏季高温),以及工业车间的高低温波动;贴片封装的抗振动、抗冲击性能优于直插,适合移动设备或振动场景(如车载、手持终端)。
支持无铅焊接(符合欧盟RoHS指令),适配现代环保生产流程;封装引脚设计合理,焊接后不易出现虚焊,长期使用可靠性高。
与同类普通32.768kHz晶振相比,3131M系列的核心优势在于:
某品牌智能手表采用该晶振后,常温下每天计时误差<2秒,电池续航提升10%(因晶振功耗低),且在-10℃冬季户外使用时,误差仍保持在±3秒/天以内,满足用户日常计时需求。
某工业传感器厂商将该晶振用于户外温湿度采集节点,-30℃~+70℃环境下,节点的时间同步误差<5秒/天,无需频繁校准,降低了运维成本。
某智能门锁品牌采用SMD3215封装的该晶振,节省了PCB空间(比直插晶振节省约1cm²),同时保证了开锁时间、告警时间的准确性,提升了用户体验。
HCI 3131M-32.768DT06LLL是一款高性价比、工业级稳定性的32.768kHz贴片晶振,适合对计时精度、宽温适应性有要求的便携式、工业、物联网设备。其小型化封装、低功耗特性,使其成为智能穿戴、智能门锁等领域的优先选择。

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.
