PK0810-680MB 非屏蔽功率电感产品概述

一、产品基本定位

PK0810-680MB是顺翔诺(SXN)品牌推出的插件式非屏蔽功率电感,针对中低功率电源电路设计,兼顾成本与性能平衡,适用于对电感尺寸、电流承载能力有明确要求的通用电子设备。产品采用径向引线封装,便于手工或自动插件作业,是替代传统电感的高性价比选型,广泛覆盖消费电子、小型电源等领域。

二、核心电气参数详解

  1. 电感值与精度:标称电感值68μH,精度±20%,满足大多数电源电路的电感量偏差需求(如DC-DC降压电路的滤波/储能要求),无需额外高精度匹配,降低设计复杂度。
  2. 额定电流:连续工作电流额定值1.2A,指电感在25℃环境下,电感量变化不超过±10%时的最大连续电流;短时间(10秒内)可承受更高电流(需参考厂商降额曲线),避免长期过载导致磁芯饱和。
  3. 直流电阻(DCR):典型值180mΩ,直接影响电感功率损耗(公式:P=I²·DCR),1.2A下损耗约0.26W,发热可控,适合小体积电路的热设计。
  4. 工作温度范围:常规型号支持-40℃~+85℃(部分批次可扩展至+105℃),满足工业级与消费级设备的环境适应性,适配车载、户外等场景。

三、结构与封装特点

  • 非屏蔽结构:采用裸磁芯(铁氧体合金材质)设计,无金属屏蔽罩,成本更低,但需注意电磁辐射(EMI)影响,建议远离敏感模拟电路(如音频、射频模块)。
  • 径向引线封装:引脚从磁芯两端径向引出,符合插件工艺标准,引脚间距与长度适配常规PCB焊盘,焊接牢固性优于贴片电感(尤其高振动场景,如车载设备)。
  • 尺寸规格:参考PK0810系列命名规则,外形尺寸约8mm×10mm(直径×高度,具体以厂商 datasheet 为准),体积紧凑,适合小型化设备内部布局(如路由器、机顶盒电源模块)。

四、典型应用场景

  1. DC-DC转换器:如5V转3.3V、12V转5V的降压电路,电感配合开关管实现高效电压转换,抑制输出纹波;
  2. LED驱动电源:小功率LED串(5-10颗)的恒流驱动电路,电感稳定电流输出,提升光效稳定性;
  3. 消费电子:路由器、机顶盒、小型充电器的电源滤波模块,满足低功耗与小体积需求;
  4. 车载辅助电路:汽车仪表盘背光、中控小功率模块的电源滤波,耐受汽车级振动与温度变化。

五、选型与使用注意事项

  1. 降额设计:实际应用建议电流不超过额定值的80%(即0.96A),避免长期过热导致磁芯老化、电感量下降;
  2. 焊接工艺:波峰焊温度建议240℃~260℃(时间≤3秒),手工焊使用25W烙铁(温度≤350℃),防止高温损坏磁芯;
  3. EMI防护:若应用于高频电路(>1MHz),需在电感周围增加屏蔽罩,或与敏感元件保持≥5mm间距;
  4. 存储要求:避免长期暴露于高湿度环境(相对湿度>85%),存储温度-5℃~+40℃,防止引脚氧化影响焊接可靠性。

该产品以高性价比、适配性强的特点,成为中低功率电源电路的主流电感选型之一,可直接替代同参数的传统插件电感,降低BOM成本。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
