PK0810-331MB是顺翔诺(SXN)品牌推出的非屏蔽径向插件功率电感,属于中低功率场景的基础型电感元件。型号命名中,“PK”代表功率电感系列,“0810”为封装尺寸标识(常规直径8mm×高度10mm),“331”对应电感值330μH(33×10¹),“MB”后缀指向基础型非屏蔽规格。该产品核心面向成本敏感、安装便捷性要求高的电子设备,适配小电流电源滤波、信号耦合等场景,无需依赖SMT贴装设备即可快速应用。
标称电感值330μH,精度±20%。该精度范围可覆盖多数民用电子设备的电源滤波需求(如5V/0.5A级电源的纹波抑制),同时兼顾生产工艺稳定性——无需额外校准即可满足批量应用,避免因参数波动导致电路调试成本增加。
500mA(DC)。此参数表示电感在持续承载500mA直流电流时,电感值变化不超过±20%精度范围,且无明显磁饱和现象。实测显示,电流≤450mA时电感值波动小于5%,可稳定支撑小功率电源模块的持续工作。
470mΩ。DCR是电感绕组铜损的核心指标,470mΩ的阻值在同类插件电感中属于合理区间:500mA电流下损耗约0.1175W,可有效降低电池供电设备(如智能手环、蓝牙耳机)的待机功耗,延长续航时间。
该电感主要适配小电流、低干扰要求的电子设备,核心场景包括:
顺翔诺(SXN)作为国内成熟电感厂商,该产品符合RoHS 2.0环保标准(无铅无镉);磁芯采用铁氧体材料,一致性控制良好(电感值波动≤±2%);直流电阻一致性≤±5%,批量应用时参数波动小,降低电路调试难度。
该产品通过了常规环境可靠性测试(高低温循环、湿度老化),可满足多数民用电子设备的基础电感需求,是小功率场景下成本与性能平衡的优选方案。

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.
